Differential expression of mitochondrial genes between queens and workers during caste determination in the honeybee Apis mellifera. (1/1920)

The nourishment received by female honeybee larvae determines their differentiation into queens or workers. In this study, we report the first molecular analysis of differences that occur between queens and workers during the caste-determination process. RNA-differential display experiments identified a clone that encodes for a gene that is homologous to the nuclear-encoded mitochondrial translation initiation factor (AmIF-2mt). Semi-quantitative analysis by reverse transcriptase/polymerase chain reaction (RT-PCR) throughout honeybee development detected a higher level of expression of this gene in queen larvae than in worker larvae. Analysis of two other genes encoding mitochondrial proteins, cytochrome oxidase subunit 1 (COX-1; mitochondrial-encoded) and cytochrome c (cyt c; nuclear-encoded) also showed differential expression of these two genes between queens and workers. In particular, the cyt c transcript is more abundant in queen larvae and throughout the metamorphosis of the queen. These results indicate that the higher respiratory rate previously documented in queen larvae is accomplished through a higher level of expression of both nuclear- and mitochondrial-encoded genes for mitochondrial proteins.  (+info)

IA in Kenyon cells of the mushroom body of honeybees resembles shaker currents: kinetics, modulation by K+, and simulation. (2/1920)

Cultured Kenyon cells from the mushroom body of the honeybee, Apis mellifera, show a voltage-gated, fast transient K+ current that is sensitive to 4-aminopyridine, an A current. The kinetic properties of this A current and its modulation by extracellular K+ ions were investigated in vitro with the whole cell patch-clamp technique. The A current was isolated from other voltage-gated currents either pharmacologically or with suitable voltage-clamp protocols. Hodgkin- and Huxley-style mathematical equations were used for the description of this current and for the simulation of action potentials in a Kenyon cell model. Activation and inactivation of the A current are fast and voltage dependent with time constants of 0.4 +/- 0.1 ms (means +/- SE) at +45 mV and 3.0 +/- 1.6 ms at +45 mV, respectively. The pronounced voltage dependence of the inactivation kinetics indicates that at least a part of this current of the honeybee Kenyon cells is a shaker-like current. Deactivation and recovery from inactivation also show voltage dependency. The time constant of deactivation has a value of 0.4 +/- 0.1 ms at -75 mV. Recovery from inactivation needs a double-exponential function to be fitted adequately; the resulting time constants are 18 +/- 3.1 ms for the fast and 745 +/- 107 ms for the slow process at -75 mV. Half-maximal activation of the A current occurs at -0.7 +/- 2.9 mV, and half-maximal inactivation occurs at -54.7 +/- 2.4 mV. An increase in the extracellular K+ concentration increases the conductance and accelerates the recovery from inactivation of the A current, affecting the slow but not the fast time constant. With respect to these modulations the current under investigation resembles some of the shaker-like currents. The data of the A current were incorporated into a reduced computational model of the voltage-gated currents of Kenyon cells. In addition, the model contained a delayed rectifier K+ current, a Na+ current, and a leakage current. The model is able to generate an action potential on current injection. The model predicts that the A current causes repolarization of the action potential but not a delay in the initiation of the action potential. It further predicts that the activation of the delayed rectifier K+ current is too slow to contribute markedly to repolarization during a single action potential. Because of its fast activation, the A current reduces the amplitude of the net depolarizing current and thus reduces the peak amplitude and the duration of the action potential.  (+info)

Biological activities of C-terminal 15-residue synthetic fragment of melittin: design of an analog with improved antibacterial activity. (3/1920)

Melittin, the 26-residue predominant toxic peptide from bee venom, exhibits potent antibacterial activity in addition to its hemolytic activity. The synthetic peptide of 15 residues corresponding to its C-terminal end (MCF), which encompasses its most amphiphilic segment, is now being shown to possess antibacterial activity about 5-7 times less compared to that of melittin. MCF, however, is 300 times less hemolytic. An analog of MCF, MCFA, in which two cationic residues have been transpositioned to the N-terminal region from the C-terminal region, exhibits antibacterial activity comparable to that of melittin, but is only marginally more hemolytic than MCF. The biophysical properties of the peptides, like folding and aggregation, correlate well with their biological properties.  (+info)

A PCR detection method for rapid identification of Paenibacillus larvae. (4/1920)

American foulbrood is a disease of larval honeybees (Apis mellifera) caused by the bacterium Paenibacillus larvae. Over the years attempts have been made to develop a selective medium for the detection of P. larvae spores from honey samples. The most successful of these is a semiselective medium containing nalidixic acid and pipermedic acid. Although this medium allows the growth of P. larvae and prevents the growth of most other bacterial species, the false-positive colonies that grow on it prevent the rapid confirmation of the presence of P. larvae. Here we describe a PCR detection method which can be used on the colonies that grow on this semiselective medium and thereby allows the rapid confirmation of the presence of P. larvae. The PCR primers were designed on the basis of the 16S rRNA gene of P. larvae and selectively amplify a 973-bp amplicon. The PCR amplicon was confirmed as originating from P. larvae by sequencing in both directions. Detection was specific for P. larvae, and the primers did not hybridize with DNA from closely related bacterial species.  (+info)

Differential gene expression between developing queens and workers in the honey bee, Apis mellifera. (5/1920)

Many insects show polyphenisms, or alternative morphologies, which are based on differential gene expression rather than genetic polymorphism. Queens and workers are alternative forms of the adult female honey bee and represent one of the best known examples of insect polyphenism. Hormonal regulation of caste determination in honey bees has been studied in detail, but little is known about the proximate molecular mechanisms underlying this process, or any other such polyphenism. We report the success of a molecular-genetic approach for studying queen- and worker-specific gene expression in the development of the honey bee (Apis mellifera). Numerous genes appear to be differentially expressed between the two castes. Seven differentially expressed loci described here belong to at least five distinctly different evolutionary and functional groups. Two are particularly promising as potential regulators of caste differentiation. One is homologous to a widespread class of proteins that bind lipids and other hydrophobic ligands, including retinoic acid. The second locus shows sequence similarity to a DNA-binding domain in the Ets family of transcription factors. The remaining loci appear to be involved with downstream changes inherent to queen- or worker-specific developmental pathways. Caste determination in honey bees is typically thought of as primarily queen determination; our results make it clear that the process involves specific activation of genes in workers as well as in queens.  (+info)

The role of orientation flights on homing performance in honeybees. (6/1920)

Honeybees have long served as a model organism for investigating insect navigation. Bees, like many other nesting animals, primarily use learned visual features of the environment to guide their movement between the nest and foraging sites. Although much is known about the spatial information encoded in memory by experienced bees, the development of large-scale spatial memory in naive bees is not clearly understood. Past studies suggest that learning occurs during orientation flights taken before the start of foraging. We investigated what honeybees learn during their initial experience in a new landscape by examining the homing of bees displaced after a single orientation flight lasting only 5-10 min. Homing ability was assessed using vanishing bearings and homing speed. At release sites with a view of the landmarks immediately surrounding the hive, 'first-flight' bees, tested after their very first orientation flight, had faster homing rates than 'reorienting foragers', which had previous experience in a different site prior to their orientation flight in the test landscape. First-flight bees also had faster homing rates from these sites than did 'resident' bees with full experience of the terrain. At distant sites, resident bees returned to the hive more rapidly than reorienting or first-flight bees; however, in some cases, the reorienting bees were as successful as the resident bees. Vanishing bearings indicated that all three types of bees were oriented homewards when in the vicinity of landmarks near the hive. When bees were released out of sight of these landmarks, hence forcing them to rely on a route memory, the 'first-flight' bees were confused, the 'reorienting' bees chose the homeward direction except at the most distant site and the 'resident' bees were consistently oriented homewards.  (+info)

Update on the status of Africanized honey bees in the western states. (7/1920)

The Africanized honey bee (AHB), Apis mellifera scutella--perhaps better known as the "killer bee"--has arrived in the western United States and in southern California, following a nearly 50-year north-ward migration across South and Central America. First detected near Hidalgo, Texas in October 1993, the bees continue to advance 100 to 300 miles per year by colonizing existing hives or forming new hives in the wild. Although the AHB's "killer" reputation has been greatly exaggerated, the presence of AHBs will increase the chances of people being stung.  (+info)

Mass envenomations by honey bees and wasps. (8/1920)

Stinging events involving honey bees and wasps are rare; most deaths or clinically important incidents involve very few stings (< 10) and anaphylactic shock. However, mass stinging events can prove life-threatening via the toxic action of the venom when injected in large amounts. With the advent of the Africanized honey bee in the southwestern United States and its potential for further spread, mass envenomation incidents will increase. Here we review the literature on mass stinging events involving honey bees and wasps (i.e., yellowjackets, wasps, and hornets). Despite different venom composition in the two insect groups, both may cause systemic damage and involve hemolysis, rhabdomyolysis, and acute renal failure. Victim death may occur due to renal failure or cardiac complications. With supportive care, however, most victims should be able to survive attacks from hundreds of wasps or approximately 1000 honey bees.  (+info)

The European honey bee (Apis mellifera) is of global importance as a pollinator. Over the past 30 years an increase in colonies lost during winter has occurred, particularly in the northern hemisphere. These losses are attributed to the ectoparasitic mite Varroa destructor that acts as a vector of RNA viruses, most notably Deformed wing virus (DWV). Three master variants of the DWV have been discovered; Type-A, B, and C. The increase in overwinter colony losses are closely linked to DWV. At the same time DWV may also offer protection to colonies via superinfection exclusion (SIE), which may be linked to Varroa-tolerant colonies. However, the role of each DWV variant in colony survivorship and mite-tolerance is limited, so the main thrust of the thesis is to address this issue ...
Honey bees (Apis mellifera L.) are the most important insect for pollination of crops and wildflowers [1-3], but they have experienced increasing colony die-offs during the past two decades [4-6]. Varroa destructor is widely considered the most serious risk factor for honey bee colony mortality worldwide [7-10]. These large ectoparasitic mites are associated with a condition known as parasitic mite syndrome (PMS), or Varroosis. In colonies exhibiting PMS or Varroosis, pathogens, including brood diseases and viruses, are present at unusually high levels [11-13]. Varroa mites feed on the hemolymph of the larva, pupa and adults, and the open wounds caused by mite feeding can allow microorganisms to enter and weaken the host [14]; Mites themselves are vectors for viruses and perhaps other bee pathogens [13]. The Varroa mites life cycle consists of two phases, the phoretic phase, during which the adult female mite lives, feeds, and disperses on the adult bee, and the reproductive phase in which ...
Honey bee (Apis mellifera) nurses do not consume pollens based on their nutritional quality Honey bee workers (Apis mellifera) consume a variety of pollens to meet the majority of their requirements for protein and lipids. Recent work indicates that honey bees prefer diets that reflect the proper ratio of nutrients necessary for optimal survival and homeostasis. This idea relies on the precept that honey bees evaluate the nutritional composition of the foods provided to them. While this has
NCERT P Bahadur IIT-JEE Previous Year Narendra Awasthi MS Chauhan. Apis is the genus name for all honey bees.Specifically, the honey bees scientific name includes at least two names. Occupations for a Honey Bee break down into one of three categories: worker bee, drone, or queen Bee. It is wrong to allocate one or the other groups of the honey bee in separate species by a small number of features (mainly morphological). The species name is Apis mellifera. A Honey bee can only sting once, then it dies. Dozens more species of solitary bee collect pollen or, like cuckoos, leave their eggs to hatch and thrive in the pollen-stocked nests of other species. There are over 20,000 species of bee, but accurate data about how these species are spread across the globe are sparse. The western honey bee or European honey bee (Apis mellifera) is the most common of the ~40 species of honey bee worldwide.The genus name Apis is Latin for bee, and mellifera means honey-bearing, referring to the species ...
Everyone needs to keep an eye out for exotic bees. Many exotic bees are hard to tell from European honey bees and they may also be carrying pests such as internal and external mites, so any evidence of bees entering Australia should be treated as a biosecurity risk.. Bees can arrive in imported goods, including vehicles and machinery, and the conveyances and containers they come in. There may be evidence of individual bees, whole swarms, or hives.. Asian honey bees (Apis cerana) originated in Indonesia, and are now established in northern Queensland around Cairns. They are smaller and less hairy than European honey bees, and their black and yellow stripes are more pronounced. They are a natural host for varroa mites, which may destroy European honey bee colonies. They are also a vector for other bee diseases and could compete with European honey bees for resources, threatening their populations. Asian honey bees are hard to manage for both honey production and pollination, and are not effective ...
3. Pathogens from green houses, urban bee keeping and managed bee populations are a major contributor to decline of wild bee populations.. North American wild bee species are facing a 30 to 90 % decline. Pathogen spillover from managed honey bees has been linked to increase in diseases among native bee populations such as Bumble Bees. Dr. Colla warns that bee keeping should be performed by trained professionals. Honey bees are aggressive competitors, have large hives and resources. Studies show honey bees can reduce forage activity of wild bees and disrupt native plant and bee relationships.. 4. Wild bees are not adapting fast enough to temperature changes and are essentially being squished in the middle of climate zones.. Wild bees live in narrow climate niches. This means that the impacts of climate change such as spring storms and late blooming of spring flowers are quite detrimental. Unlike some other species that are moving north with rising temperatures, bee populations are not able to ...
A sublethal concentration of imidacloprid can cause chronic toxicity in bees and can impact the behavior of honey bees. The nectar- and water-collecting, and climbing abilities of bees are crucial to the survival of the bees and the execution of responsibilities in bee colonies. Besides behavioral impact, data on the molecular mechanisms underlying the toxicity of imidacloprid, especially by the way of RNA-seq at the transcriptomic level, are limited. We treated Apis mellifera L. with sublethal concentrations of imidacloprid (0.1, 1 and 10 ppb) and determined the effect on behaviors and the transcriptomic changes. The sublethal concentrations of imidacloprid had a limited impact on the survival and syrup consumption of bees, but caused a significant increase in water consumption. Moreover, the climbing ability was significantly impaired by 10 ppb imidacloprid at 8 d. In the RNA-seq analysis, gene ontology (GO) term enrichment indicated a significant down-regulation of muscle-related genes, which might

Y1 - 2008/11. N2 - A defining characteristic of eusocial animals is their division of labour into reproductive and nonreproductive specialists. Here, we used a microarray study to identify genes associated with functional sterility in the worker honey bee Apis mellifera. We contrasted gene expression in workers from a functionally sterile wild‐type strain with that in a mutant (anarchist) strain selected for high rates of ovary activation. We identified a small set of genes from the brain (n = 7) and from the abdomen (n = 5) that are correlated in their expression with early stages of ovary activation. Sterile wild‐type workers up‐regulated two unknown genes and a homologue of Drosophila CG6004. By contrast, reproductive anarchist workers up‐regulated genes for the yolk protein vitellogenin, venom ...
In the Western honey bee, Apis mellifera, queens and workers have different longevity although they share the same genome. Queens consume royal jelly (RJ) as the main food throughout their life, including as adults, but workers only eat worker jelly when they are larvae less than 3 days old. In order to explore the effect of RJ and the components affecting longevity of worker honey bees, we first determined the optimal dose for prolonging longevity of workers as 4% RJ in 50% sucrose solution, and developed a method of obtaining long lived workers. We then compared the effects of longevity extension by RJ 4% with bee-collected pollen from rapeseed (Brassica napus). Lastly, we determined that a water soluble RJ protein obtained by precipitation with 60% ammonium sulfate (RJP60) contained the main component for longevity extension after comparing the effects of RJ crude protein extract (RJCP), RJP30 (obtained by precipitation with 30% ammonium sulfate), and RJ ethanol extract (RJEE). Understanding what
Honey bees are major pollinators of agricultural and non-agricultural landscapes. In recent years, honey bee colonies have exhibited high annual losses and commercial beekeepers frequently report poor queen quality and queen failure as the primary causes. Honey bee colonies are highly vulnerable to compromised queen fertility, as each hive is headed by one reproductive queen. Queens mate with multiple drones (male bees) during a single mating period early in life in which they obtain enough spermatozoa to fertilize their eggs for the rest of their reproductive life span. The process of mating initiates numerous behavioral, physiological, and molecular changes that shape the fertility of the queen and her influence on the colony. For example, receipt of drone semen can modulate queen ovary activation, pheromone production, and subsequent worker retinue behavior. In addition, seminal fluid is a major component of semen that is primarily derived from drone accessory glands. It also contains a complex
Deformed wing virus (DWV) in association with Varroa destructor is currently attributed to being responsible for colony collapse in the western honey bee (Apis mellifera). The appearance of deformed individuals within an infested colony has long been associated with colony losses. However, it is unknown why only a fraction of DWV positive bees develop deformed wings. This study concerns two small studies comparing deformed and non-deformed bees. In Brazil, asymptomatic bees (no wing deformity) that had been parasitised by Varroa as pupae had higher DWV loads than non-parasitised bees. However, we found no greater bilateral asymmetry in wing morphology due to DWV titres or parasitisation. As expected, using RT-qPCR, deformed bees were found to contain the highest viral loads. In a separate study, next generation sequencing (NGS) was applied to compare the entire DWV genomes from paired symptomatic and asymptomatic bees from three colonies on two different Hawaiian islands. This revealed no ...
Neonicotinoid compounds act as agonists of nicotinic acetylcholine receptors (nAChRs) [27]. They cause persistent activation of cholinergic receptors, leading to hyperexcitation and eventual death [28]. As seen in Figure 2a, imidacloprid has a stimulatory effect on locomotor activity at the lowest level of exposure, but an opposite effect at the highest concentrations. Similar results have been documented by Lambin et al. [29], who reported increased motor activity following topical application of imidacloprid at 1.25 ng per bee but a decrease in mobility of bees treated with >5 ng per bee. The stimulatory effect may be indicative of nicotinic activation by low doses of the insecticide, whereas a nonspecific toxic effect is seen at higher doses. Although the oral LD50 of neonicotinoids is much higher than the estimated daily ingestion of a forager [30], if treated crop plants constitute the majority of a colonys nectar and pollen resources while in bloom, multiple exposures to sublethal levels ...
All honey bees live in colonies where the worker bees will sting intruders as a form of defense, and alarmed bees will release a pheromone that stimulates the attack response in other bees. The different species of honey bees are distinguished from all other bee species (and virtually all other Hymenoptera) by the possession of small barbs on the sting, but these barbs are found only in the worker bees. The sting and associated venom sac are also modified so as to pull free of the body once lodged (autotomy), and the sting apparatus has its own musculature and ganglion which allow it to keep delivering venom once detached. The worker bee dies after the stinger is torn from its body. As with other forms of life, warnings are given before an attack is launched. In the case of some honey bees species in the wild, this takes the form of a Mexican wave which spreads as a ripple across a layer of bees densely packed on the surface of a comb when a threat is perceived, and consists of bees ...
The life cycle of a honey bee is broken down into three different stages. The three stages are the larval, pupal and adult phases. The queen bee is the only egg laying bee in an entire hive. She can lay either fertilized or unfertilized eggs. Fertilized eggs become either worker bees or queen bees. Unfertilized eggs become drone bees. Eggs in the hive hatch 3 days after they were laid. Worker bees, drone bees and queen bees all have different jobs in the hive.. Worker bees hatch from a fertilized egg and are the female bees. After the female bees hatch, they spend around 6 days in the larval stage. In the larval stage, the bees are fed between 150-800 times per day by the adult worker bees. At this time, fat bodies are being built so that the bee has an adequate amount of storage for lipids, glycogen, amino acids and mitochondria for the bee during the pupal stage. After about 8 or 9 days, the cells with these larva are capped and the larva begin to grow. The pupal stage is the most important ...
A laying worker bee is a worker bee that lays unfertilized eggs usually in the absence of a queen bee (cf gamergates in ants). Only drones develop from the eggs of laying worker bees (with some exceptions, see thelytoky). A beehive cannot survive with only a laying worker bee. Even in a normal hive, about 1% of workers have ovaries developed enough to lay eggs. However the usual number of the laid eggs is very small. Only eight eggs (seven moderately and one fully developed) were found after examining of 10,634 worker bees (strong colony contains about 100,000). Workers eventually lay significant numbers of eggs only in queenless colonies. Laying workers develop in the absence of open brood as produced by a healthy adult queen. Normally, pheromones from the brood - known as brood recognition pheromones - prevent development of the workers ovaries. Laying workers can develop after the colonys queen has been lost to swarming, or in the presence of a failing queen which has yet to be superseded. ...
TY - JOUR. T1 - Artificial bee colony algorithm with memory. AU - Li, Xianneng. AU - Yang, Guangfei. PY - 2016/4/1. Y1 - 2016/4/1. N2 - Artificial bee colony algorithm (ABC) is a new type of swarm intelligence methods which imitates the foraging behavior of honeybees. Due to its simple implementation with very small number of control parameters, many efforts have been done to explore ABC research in both algorithms and applications. In this paper, a new ABC variant named ABC with memory algorithm (ABCM) is described, which imitates a memory mechanism to the artificial bees to memorize their previous successful experiences of foraging behavior. The memory mechanism is applied to guide the further foraging of the artificial bees. Essentially, ABCM is inspired by the biological study of natural honeybees, rather than most of the other ABC variants that integrate existing algorithms into ABC framework. The superiority of ABCM is analyzed on a set of benchmark problems in comparison with ABC, quick ...
Although Apis mellifera, the western honey bee, has long encountered pesticides when foraging in agricultural fields, for two decades it has encountered pesticides in-hive in the form of acaricides to control Varroa destructor, a devastating parasitic mite. The pyrethroid tau-fluvalinate and the organophosphate coumaphos have been used for Varroa control, with little knowledge of honey bee detoxification mechanisms. Cytochrome P450-mediated detoxification contributes to pyrethroid tolerance in many insects, but specific P450s responsible for pesticide detoxification in honey bees (indeed, in any hymenopteran pollinator) have not been defined. We expressed and assayed CYP3 clan midgut P450s and demonstrated that CYP9Q1, CYP9Q2, and CYP9Q3 metabolize tau-fluvalinate to a form suitable for further cleavage by the carboxylesterases that also contribute to tau-fluvalinate tolerance. These in vitro assays indicated that all of the three CYP9Q enzymes also detoxify coumaphos. Molecular models ...

Y1 - 2003/11/15. N2 - We tested the hypothesis that queen mandibular pheromone (QMP) causes changes in gene expression in the brain of the adult worker honey bee, and that these changes can be correlated to the downstream behavioral responses induced by QMP. In support of the first hypothesis, cage experiments revealed that QMP transiently regulated expression of several hundred genes and chronically regulated the expression of 19 genes. Several of these genes were also affected by QMP in experiments with bee colonies in the field, demonstrating robust gene regulation by pheromone. To evaluate the second hypothesis, we focused on one function of QMP: delaying the transition from working in the hive (e.g., brood care, or nursing) to foraging. We compared the list of QMP-regulated genes with the ...
The mite Varroa destructor is one of the most dangerous parasites of the Western honeybee (Apis mellifera) causing enormous colony losses worldwide. Various chemical treatments for the control of the Varroa mite are currently in use, which, however, lead to residues in bee products and often to resistance in mites. This facilitated the exploration of alternative treatment methods and breeding for mite resistant honeybees has been in focus for breeders in many parts of the world with variable results. Another approach has been applied to a honeybee population on Gotland (Sweden) that was exposed to natural selection and survived Varroa-infestation for more than 10 years without treatment. Eventually this population became resistant to the parasite by suppressing the reproduction of the mite. A previous QTL mapping study had identified a region on chromosome 7 with major loci contributing to the mite resistance. Here, a microsatellite scan of the significant candidate QTL regions was used to ...
The honey bee Apis mellifera plays an important role for the pollination of fruit and vegetable plants, besides its significance for the production of honey and wax. Losses of entire bee colonies during winter have economic and - in particular - ecological consequences as pollinators are missing in spring during blossom. Apiculture in North America and Europe is especially affected by partly massive losses. Only during the winter months of 2014/2015, up to fifty per cent of all bee colonies in some Austrian regions collapsed.. The main trigger of this bee mortality does not seem to be the use of pesticides in modern agriculture. Many studies have shown that the survival of bee colonies strongly depends on the infestation with Varroa mites, widespread blood-sucking parasites, and the transmission of deformed wing virus by these mites. A research group from the Institute of Virology at the University of Veterinary Medicine, Vienna has developed a new laboratory system, which enabled them to make ...
The European honeybee, Apis mellifera, has been the object of considerable scientific curiosity and has served as the classical model organism in diverse fields such as behaviour, navigation, sensory biology, ecology and pollination biology for almost a century (Frisch, 1914; Frisch, 1927). Apis mellifera has eight congeners, all of which are Asian, and about which much less is known. Of the Asian honeybees, the cavity-nesting Apis cerana and the less well known species Apis koshevnikovi, Apis nigrocincta and Apis nuluensis are closely related to A. mellifera whereas the giant honeybees (Apis dorsata, Apis dorsata binghami and Apis laboriosa) and the dwarf honeybees (Apis florea and Apis andreniformis) form separate groups (Arias and Sheppard, 2005; Raffiudin and Crozier, 2007). Although A. mellifera is found in Africa, the Urals and Central Asia, it is allopatric to the south and south-east Asian species, many of which are sympatric in several tropical areas of Asia. For instance, in the ...
Deformed wing virus (DWV) is a positive-strand RNA virus that infects European honeybees (Apis mellifera L.) and has been isolated from the brains of aggressive bees in Japan. DWV is known to be transmitted both vertically and horizontally between bees in a colony and can lead to both symptomatic and asymptomatic infections in bees. In environmentally stressful conditions, DWV can contribute to the demise of a honeybee colony. The purpose of the current study is to identify regions within the brains of honeybees where DWV replicates using in-situ hybridization. In-situ hybridizations were conducted with both sense and antisense probes on the brains of honeybees that were positive for DWV as measured by real-time RT-PCR. The visual neuropils demonstrated detectable levels of the DWV positive-strand genome. The mushroom bodies and antenna lobe neuropils also showed the presence of the viral genome. Weaker staining with the sense probe in the same regions demonstrates that the antigenome is also present
Coloured scanning electron micrograph (SEM) of Honey bee head (Apis mellifera). Wikipedia reference: The western honey bee or European honey bee (Apis mellifera) is a species of honey bee. It has a defined social caste system and complex communication behaviours, such as intricate dance routines to indicate food availability. It is frequently maintained by beekeepers for its honey product. This species is widely distributed and an important pollinator for agriculture, though it is currently threatened by colony collapse disorder. It is also an important organism for scientific studies on social insects, especially as it now has a fully sequenced genome.

Honey bee (Apis mellifera) is an insect species living in colonies. In the colony there is usually one queen, thousands of workers and during some parts of the year variable number of drones. New colonies are produced by swarming. The colony lives in a nest which in nature is usually located inside a hollow tree. In the nest there is a series of vertical combs build from wax. On two sides of the combs there are hexagonal cells. Larval development of bees occurs in the cells. They are also used for storing honey and bee bread. The main food of honey bees are pollen and nectar collected from flowers. Originally honey bees occurred in Africa, Europe (except northern part) and Near East. They were introduced by man to Asia, both American continents and Australia. Domesticated honey bees are kept in hives. They are important economically as pollinators of crops and producers of honey ...
Apis mellifera, the European honey bee, has many subspecies. Apis mellifera adami, classified by Ruttner, 1975 - Crete Apis mellifera carnica, classified by Pollmann, 1879 - Carniola region of Slovenia, the Eastern Alps, and northern Balkans - better known as the Carniolan honey bee - popular with beekeepers due to its extreme gentleness. The Carniolan tends to be quite dark in color, and the colonies are known to shrink to small populations over winter, and build very quickly in spring. It is a mountain bee in its native range, and is a good bee for colder climates. Apis mellifera cecropia, classified by Kiesenwetter, 1860 - Southern Greece Apis mellifera cypria, classified by Pollmann, 1879 - The island of Cyprus - This sub-species has the reputation of being very fierce compared to the Italian sub-species, from which it is isolated by the Mediterranean Sea Apis mellifera iberiensis (often misspelled as iberica), classified by Engel, 1999 - the bee from the Iberian peninsula (Spain and ...

Journal of Insect Physiology. 54:215-221. Interpretive Summary: Honey bee Colony Collapse Disorder is exerting tremendous impact on honey bee colonies. This is a devastating, yet poorly understood, crisis for commercial beekeepers and crop growers who depend on honey bees to pollinate their crops. The problem, however, may be related to an unknown disease or perhaps to impaired honey bee immunity to diseases. One approach to understanding the problem is to more thoroughly research honey bee immunology. With this goal, we are investigating the capacity for immunity in adult honey bees. In this paper we report on changes in honey bee blood cells, the cells that protect honey bees from infection. We show for the first time that adult queens, workers and drones naturally lose their hemocytes. This work with entirely healthy ...
Yañez O, Chávez-Galarza J, Tellgren-Roth C, Pinto MA, Neumann P, de Miranda JR Sci Rep 10 (1) 5956 [2020-04-06; online 2020-04-06] The main biological threat to the western honeybee (Apis mellifera) is the parasitic mite Varroa destructor, largely because it vectors lethal epidemics of honeybee viruses that, in the absence of this mite, are relatively innocuous. The severe pathology is a direct consequence of excessive virus titres caused by this novel transmission route. However, little is known about how the virus adapts genetically during transmission and whether this influences the pathology. Here, we show that upon injection into honeybee pupae, the deformed wing virus type-A (DWV-A) quasispecies undergoes a rapid, extensive expansion of its sequence space, followed by strong negative selection towards a uniform, common shape by the time the pupae have completed their development, with no difference between symptomatic and asymptomatic adults in either DWV titre or genetic composition. ...
This paper proposes a global multi-level thresholding method for image segmentation. As a criterion for this, the traditional method uses the Shannon entropy, originated from information theory, considering the gray level image histogram as a probability distribution, while we applied the Tsallis entropy as a general information theory entropy formalism. For the algorithm, we used the artificial bee colony approach since execution of an exhaustive algorithm would be too time-consuming. The experiments demonstrate that: 1) the Tsallis entropy is superior to traditional maximum entropy thresholding, maximum between class variance thresholding, and minimum cross entropy thresholding; 2) the artificial bee colony is more rapid than either genetic algorithm or particle swarm optimization. Therefore, our approach is effective and rapid.
When it becomes warm again in spring and the first blossoms and bushes begin to bloom, the bees also begin to swarm. There is a lot to tell about bees that is worth knowing and is exciting and interesting.. Like ants and wasps, bees belong to the order of hymenoptera (membrane-winged). The bee family is divided into honeybees and bumblebees. It is especially interesting that bees live together in a large colony. There is a queen bee, and she is the only bee that lays eggs, from which the offspring are hatched. Besides a few males (the so-called drones), a bee colony consists primarily of female worker bees that have different tasks. During her life, a worker bee repeatedly takes on new tasks, depending on her age. At the beginning of her life, a bee looks after the honeycomb cells and prepares them for the queens eggs. She then becomes a nurse bee and feeds the larvae (= bee babies) with nectar. Later she can then produce wax with the glands on her posterior and build honeycombs. There are ...
Unless we take decisive action to protect our bees, we could be faced with massive bee deaths, a horticultural industry in crisis, food shortages and escalating food prices.. The honey bee is indispensable to our horticulture, our ecology and our economy. Yet the honey bee is in crisis all around the world, with bee populations being decimated by a phenomenon known as Colony Collapse Disorder, where entire colonies of bees disappear.. In the US beekeepers have been experiencing annual losses ranging from 30 to 90% of their commercially managed hives for the past five years. And tens of thousands of bee colonies have been wiped out in Europe, Asia and the Middle East.. Similar losses in New Zealand would be disastrous for our horticultural industries that depend on bees for pollination, and so we need to take steps to protect our bees before it is too late. We cannot wait until bees are dying en masse before we act.. Colony Collapse Disorder hasnt been detected in New Zealand yet, but there have ...
Flowering strips - pollinator-friendly rows of plants that increase foraging habitat for bees - can help offset pollinator decline but may also bring risks of higher pathogen infection rates for pollinators foraging in those strips.. Researchers from North Carolina State University and the University of Massachusetts Amherst show that flowering strip plants generally benefitted bee colony reproduction by adding floral resources for common eastern bumble bees (Bombus impatiens). The results came with a tradeoff, however, as bumble bees exposed to certain plants showed higher rates of infection by a bee pathogen acquired on flowers - Crithidia bombi, which is associated with reduced bee-foraging abilities as well as mortality in food-compromised bees.. The study showed that certain high-infection plants doubled C. bombi infection intensity when compared with low-infection plant species. Bees feeding mostly on canola plants - a major bee foraging plant and important U.S. crop - showed infection ...

Species of Honey bee are: (1) Apis mellifera - Italian bee, (2) Apis dorsata- Rock bee - largest, (3) Apis indica- Indian bee, (4) Apis florea- Little bee - smallest. Most common Indian honey bee in wild state is Apis indica, however in domestic state; the most common Indian honey bee is Apis mellifera (Italian honey bee). Honey bees are colonial, social and polymorphic insects. Unfertilized eggs develop into drones (males) by parthenogenesis. Fertilized eggs develop into queens or workers. Three types of individuals (castes) are found in the colony of honey bees: (i) Queen is a fertile female, (ii) Drones are males. Life span of a drone is 1-2 months, (iii) Workers are sterile females and perform various duties of the colony. The queens are fed by the workers. The abdomen contains the wax glands and the sting. The worker bees of a hive fall into three major castes: (a) Scavenger or Sanitary bees. For the first three days each worker bee acts a scaven-ger. (b) House or Nurse bees. From the ...
So, how long do honey bees live? Do beekeepers need to buy new bees every few months? Answer: Absolutely not! This is one of the great things about honey bees. Unlike other animals (cows, goats, sheep, etc.) which eventually die, the honey bee colony really never dies! Well almost never - in the winter, about 5% of colonies may expire. In the spring, the beekeeper simply catches swarms that leave the good, strong hives that survived the winter - free of charge! Good beekeepers can keep their bees alive for many years by simply catching those wayward swarms or splitting good hives to replace any losses. Effectively, a beekeeper may never spend money on bees or queens - once the bee business is established. You have to think of the honey bees colony - with its queen, drones, and workers - as a single living creature. On its own, a single bee (even a cluster of a hundred bees) is useless for producing honey or pollinating flowers. It takes the team work of the entire hive to make honey. This means ...
Background In 2010 Colony Collapse Disorder (CCD), again devastated honey bee colonies in the USA, indicating that the problem is neither diminishing nor has it been resolved. Many CCD investigations, using sensitive genome-based methods, have found small RNA bee viruses and the microsporidia, Nosema apis and N. ceranae in healthy and collapsing colonies alike with no single pathogen firmly linked to honey bee losses. Methodology/Principal Findings We used Mass spectrometry-based proteomics (MSP) to identify and quantify thousands of proteins from healthy and collapsing bee colonies. MSP revealed two unreported RNA viruses in North American honey bees, Varroa destructor-1 virus and Kakugo virus, and identified an invertebrate iridescent virus (IIV) (Iridoviridae) associated with CCD colonies. Prevalence of IIV significantly discriminated among strong, failing, and collapsed colonies. In addition, bees in failing colonies contained not only IIV, but also Nosema. Co-occurrence of these microbes
A honey bee that is away from the hive foraging for nectar or pollen will rarely sting, except when stepped on or roughly handled. Honey bees will actively seek out and sting when they perceive the hive to be threatened, often being alerted to this by the release of attack pheromones (below). Although it is widely believed that a worker honey bee can sting only once, this is a partial misconception: although the stinger is in fact barbed so that it lodges in the victims skin, tearing loose from the bees abdomen and leading to its death in minutes, this only happens if the skin of the victim is sufficiently thick, such as a mammals.[3] Honey bees are the only hymenoptera with a strongly barbed sting, though yellow jackets and some other wasps have small barbs. Bees with barbed stingers can often sting other insects without harming themselves. Queen honeybees and bees of many other species, including bumblebees and many solitary bees, have smoother stingers with smaller barbs, and can sting ...
Most insects and bee species live solitary or in small groups. Honeybees (Apis mellifera) however, share their hive with thousands of individuals. Only the queen and the male drones are responsible for the reproduction. The queen lays either unfertilized eggs which develop into male drones or fertilized eggs which develop into worker honeybees. The worker honeybees perform all tasks necessary for the colony and show a sophisticated, age-dependent division of labor (DoL). After emergence, young honeybees work in the center of the hive. They perform nursing tasks like cleaning cells or feeding larvae. After about three weeks, these nurse bees change their task completely and become foragers. Forager leave the hive and search for pollen, nectar or water. This transition is mainly age dependent. Yet under some conditions, young nurse bees can also become foragers, for example, if a lot of foragers are removed from the hive. Yet, until this day, the molecular basis of this nurse-forager transition ...

The results of this research will be used by other scientists investigating honey bee viruses and by federal regulatory personnel involved in the worldwide trade in honey bees. Ultimately, this research will benefit beekeepers by improving ...
Causes of bee. Commonly many types of insect are useful to people but some insects are harmful. One of that harmful insect is bees. Bee provides honey and also it causes some diseases. It is the flying stinging insects. Various type of bees are available, they are honey bees, hornets, wasps and yellow jackets. These different types of bees are differed in shape, structure and their characters. The most common properties of bees are bite. If anybody disturbed, the bees will bite them. If bees bite your skin, then skin changes in reddish color. The swelling of bees causes infection. Sometimes you feel itching in entire body. Many harmful bees are in this world, if it bites it causes breathing problem and shock also. The fire ant sting is one of the common bees. It swollen immediately causes pain on that location and changes dark red color. In case of swollen which is easily disappears within 45 minutes, does not required any treatment. But in some cases it will take long time to cure. View the bee ...
When we think of pollination we imagine a honey bee foraging on a flower, collecting nectar or pollen, and inadvertently transferring some of the pollen to the next flower she visits.. Ive always thought that solitary bees might be more efficient pollinators for several reasons. For example, solitary bees seem to fly faster between flowers, collect pollen more quickly, and take little nectar compared to honey bees. In addition, solitary bees carry their pollen in its natural fluffy state that is readily usable by flowers.. On the other hand, honey bees and bumble bees glue their pollen loads together with nectar, making a tightly-packed pellet that is useless for pollination. In fact, most of the pollen that honey bees transfer from flower to flower is stuck to their bodies in random places. When foraging on the next flower, some of this pollen rubs onto the stigma and pollinates the flower, but the pollen in the pellets doesnt budge.. Other habits of honey bees make them excellent ...
The honey bee is an important model system for increasing understanding of molecular and neural mechanisms underlying social behaviors relevant to the agricultural industry and basic science. The western honey bee, Apis mellifera, has served as a model species, and its genome sequence has been published. In contrast, the genome of the Asian honey bee, Apis cerana, has not yet been sequenced. A. cerana has been raised in Asian countries for thousands of years and has brought considerable economic benefits to the apicultural industry. A cerana has divergent biological traits compared to A. mellifera and it has played a key role in maintaining biodiversity in eastern and southern Asia. Here we report the first whole genome sequence of A. cerana. Using de novo assembly methods, we produced a 238 Mbp draft of the A. cerana genome and generated 10,651 genes. A.cerana-specific genes were analyzed to better understand the novel characteristics of this honey bee species. Seventy-two percent of the A. cerana
Summary Arkansas bee virus, bee virus X and slow paralysis virus, isolated from adult honey bees, have isometric particles, contain RNA and are serologically unrelated to each other or to the other known bee viruses. Arkansas bee virus particles are 30 nm in diam. sediment at 128S, have a buoyant density in CsCl of 1.37 g/ml and kill bees injected with them in about 3 weeks. Bee virus X particles are 35 nm in diam., sediment at 187S, have a buoyant density of 1.36 g/ml, multiply when fed to young bees kept at 30 °C but not at 35 °C nor when injected, and have not by themselves been associated with symptoms or mortality, although they killed bees when injected in combination with sacbrood virus. Slow paralysis virus particles are 30 nm in diam., sediment at about 176S, have a buoyant density of 1.35 g/ml and kill bees injected with them in about 12 days.
April Flowers for - Your Universe Online. A new study suggests that the reason worker bees are such a highly skilled and specialized workforce is that the genes controlling their behavior are re-shuffled frequently, helping evolution build a better bee.. The new research from York University, published in the Proceedings of the National Academy of Sciences (PNAS), sheds light on how sterile worker bees evolved charismatic and cooperative behaviors. These behaviors include nursing young bees, collecting food for the colony, defending it against intruders, and dancing to communicate the location of profitable flowers to nest mates.. By examining the honey bee genome, the team noticed that the genes associated with worker behavior were found in the area of the genome known to have the highest rate of recombination, which is basically a shuffling of the genetic deck. Biology Professor Amro Zayed says that because of such shuffling, the bees can be strongly varied. For example the ...
Last weekend, my daughter asked me how bees made honey, and I realized that I didnt know the answer. How do bees make honey? I did some homework, and can now explain it to her - and to you.. Different honey bees have different jobs. Some of these bees are forager bees, which collect nectar from flowering plants. The foragers drink the nectar, and store it in their crop, which is also called the honey stomach. The crop is used solely for storage, and the bee does not digest the nectar at all.. The forager bee then takes the nectar back to the hive, regurgitating the nectar directly into the crop of a processor bee at or near the entrance to the hive.. While the forager heads back to the flowers for more nectar, the processor bee takes the nectar to the honeycomb, which tends to be near the top of the hive, and regurgitates it into a hexagonal wax cell. But now the nectar needs to ripen.. The processor bees add an enzyme called invertase every time they regurgitate their nectar (and it takes ...
Reduced SNP Panels for Genetic Identification and Introgression Analysis in the Dark Honey Bee (Apis mellifera mellifera) Beekeeping activities, especially queen trading, have shaped the distribution of honey bee (Apis mellifera) subspecies in Europe, and have resulted in extensive introductions of two eastern European C-lineage subspecies (A. m. ligustica and A. m. carnica) into the native range of the M-lineage A. m. mellifera subspecies in Western Europe. As a consequence, replacement and
The demand for honey and other beehive products has necessitated different methods of hunting ranging from wild to modern beekeeping methods. The influence of two different nesting habitats on the gut enzyme activities and heavy metal content of honey-bee workers was investigated in this study. Worker bees of Apis mellifera L. were randomly collected from the wild and Kenya top bar hives were analysed for the presence of heavy metals (Pb, Zn, Cd, Mn and Cu). Gut enzymes (cellulase, amylase, α-glucosidase, proteinase and lipase) assay was also determined in worker bees from the two habitats. Worker bees from the Kenya top bar hives recorded significantly higher heavy metals in their body than worker bees from the wild. Similarly, no Cd and Pb were detected in the body of worker bees from the wild. The gut enzymes assay of worker bees from Kenya top bar hives revealed the presence of cellulase, amylase, glucosidase, proteinase and lipase with a significantly higher enzymes activities (1.10, 1.65, 0.89, 0
The bees are important pollinators of night-blooming plants and the female bees can nest alone or live in small colonies. A colony is typically made up of two to four individuals - a queen and her offspring.. Behavioral observations showed that non-reproductive foragers and guards are significantly smaller than the queen bee in a nest, although the relative size of individual bees varied from nest to nest. Heres where the flies apparently fit in and are affecting the bees behavior. The bees nest in hollowed twigs and sticks hanging in the tropical understory and the flies flick their eggs into the entrance to the bee nests. Some of these eggs randomly fall into cells, or chambers, prepared by the bees, each to hold a larva and pollen that the larva eats. The cells are then sealed, so if a cell does contain fly eggs the young flies are competing with the bee larva for a limited amount of food.. There is a natural size variation in bees and this is based in part on the amount of food available ...
European honey bees, Apis mellifera, play a critical role in the pollination of important crops. However, honey bee populations have suffered high losses in much of the world (1), coincident with an increase in agricultural demand for honey bee pollination (2). Specifically, honey bee colony losses in the United States have been exacerbated since the report of colony collapse disorder (CCD), a syndrome that comprises large-scale, unexplained losses of managed honey bees (3-9). High levels of parasites and pathogens have been linked to the decline of honey bee colonies (10, 11).. Nosema is a genus of obligate, intracellular microsporidian parasites that infect many diverse animal species, including honey bees (12, 13). For years, Nosema disease of European honey bees was exclusively attributed to a single Nosema species, Nosema apis. Another species, Nosema ceranae, was originally detected in Asian honey bees, Apis cerana (14), and subsequently found to infect European honey bees, A. mellifera ...
TY - JOUR. T1 - Physiological and Behavioral Changes in Honey Bees (Apis mellifera) Induced by Nosema ceranae Infection. AU - Goblirsch, Mike. AU - Huang, Zachary Y.. AU - Spivak, Marla. PY - 2013/3/6. Y1 - 2013/3/6. N2 - Persistent exposure to mite pests, poor nutrition, pesticides, and pathogens threaten honey bee survival. In healthy colonies, the interaction of the yolk precursor protein, vitellogenin (Vg), and endocrine factor, juvenile hormone (JH), functions as a pacemaker driving the sequence of behaviors that workers perform throughout their lives. Young bees perform nursing duties within the hive and have high Vg and low JH; as older bees transition to foraging, this trend reverses. Pathogens and parasites can alter this regulatory network. For example, infection with the microsporidian, Nosema apis, has been shown to advance behavioral maturation in workers. We investigated the effects of infection with a recent honey bee pathogen on physiological factors underlying the division of ...
Background Melissococcus plutonius is an entomopathogenic bacterium that causes European foulbrood (EFB), a honeybee (Apis mellifera L.) disease that necessitates quarantine in some countries. In Czechia, positive evidence of EFB was absent for almost 40 years, until an outbreak in the Krkonose Mountains National Park in 2015. This occurrence of EFB gave us the opportunity to study the epizootiology of EFB by focusing on the microbiome of honeybee workers, which act as vectors of honeybee diseases within and between colonies. Methods The study included worker bees collected from brood combs of colonies (i) with no signs of EFB (EFB0), (ii) without clinical symptoms but located at an apiary showing clinical signs of EFB (EFB1), and (iii) with clinical symptoms of EFB (EFB2). In total, 49 samples from 27 honeybee colonies were included in the dataset evaluated in this study. Each biological sample consisted of 10 surface-sterilized worker bees processed for DNA extraction. All subjects were analyzed using
Abstract. The microsporidia Nosema apis (Zander) and Nosema ceranae (Fries) are common intestinal parasites in honey bee (Apis mellifera L.) colonies. Though globally prevalent, there are mixed reports of Nosema infection costs, with some regions reporting high parasite virulence and colony losses, while others report high Nosema prevalence but few costs. Basic and applied studies are urgently needed to help beekeepers effectively manage Nosema spp., ideally through an integrated pest management approach that allows beekeepers to deploy multiple strategies to control Nosema when Nosema is likely to cause damage to the colonies, rather than using prophylactic treatments. Beekeepers need practical and affordable technologies that facilitate disease diagnosis and science-backed guidelines that recommend when, if at all, to treat infections. In addition, new treatment methods are needed, as there are several problems associated with the chemical use of fumagillin (the only currently extensively ...

Results from the analysis for presence and amount of apalbumin1 in honeys will be used for high-throughput screening of honey samples over the world. On the basis of our experiments which show that royal jelly proteins are regular and physiologically active components of honey we propose to change the definition of honey (according to the EU Honey Directive 2001/110/EC) as follows: Honey is a natural sweet substance produced by honey bees from nectar of plants or from secretions of plants, or excretions of plant sucking insects, which honey bees collect, transform by combining with major royal jelly proteins and other specific substances of their own, deposit, dehydrate, store and leave in the honey comb to ripen and mature ...
Deformed wing virus (DWV) is a lethal virus of honeybees (Apis mellifera) implicated in elevated colony mortality rates worldwide and facilitated through vector transmission by the ectoparasitic mite Varroa destructor. Clinical, symptomatic DWV infections are almost exclusively associated with high …
All animals are afflicted by a wide range of pests and parasites. Many are relatively benign. But for the honey bee one gut parasite in particular is a major risk, especially as summers become warmer.. Bees are fairly used to parasites. A native single-celled (microsporidian) parasite of the honey bee called Nosema apis has probably co-existed with its host for millions of years. Back in the 1990s Ingemar Fries, a world expert in honey bee pathology, visited Beijing where he came across a subtly different and novel variant of N. apis in the eastern honey bee. He named it Nosema ceranae.. Fries thought nothing more of his scientific paper describing the species, until the same parasite was found a decade later in western honey bees (the species native to Europe) in Spain, Taiwan and Vietnam.. This prompted a team of scientists, including me, to search for the parasite in honey bees across the world. If a recently discovered virus had jumped species and was spreading globally, that was big news ...
Nearly 30 percent of all honey bees literally disappeared last winter, fleeing their hives never to return. Researchers have studied colony collapse disorder since it was identified in 2006. They are now uncovering answers to this problem. A combination of factors contribute to colony collapse disorder, or CCD, including pesticide exposure, environmental and nutritional stresses, new or reemerging pathogens and a virus that targets the bees immune systems, said Keith Delaplane, an entomologist with the University of Georgia College of Agricultural and Environmental Sciences.
The decline in honey bee health is a complex problem caused by a combination of stressors, and at EPA we are committed to continuing our work with USDA, researchers, beekeepers, growers and the public to address this challenge, said Acting EPA Administrator Bob Perciasepe. The report weve released today is the product of unprecedented collaboration, and our work in concert must continue. As the report makes clear, weve made significant progress, but there is still much work to be done to protect the honey bee population ...
A second species, Nosema ceranae, a natural associate of the eastern honey bee Apis cerana, has emerged in recent years as a problem in Europe, mainly Spain, where it is suspected of causing large-scale colony deaths. N. ceranae is known to occur in the US as well, and it probably contributes to similar occurrences of colony morbidity. It is nearly impossible to discriminate N. apis from N. ceranae without molecular techniques. Being a non-natural parasite on A. mellifera, there is concern that N. ceranae may have higher virulence toward the western honey bee - a pattern typical with many non-natural parasite relationships. However, studies from Canada and the US have failed to firmly associate Nosema disease with wide-scale colony deaths in the mid-to-late 2000s, sometimes called Colony Collapse Disorder (CCD).. There are no IPM approaches specifically targeted against Nosema disease, and its management centers on the maintenance of robust colonies and biennial application of the antibiotic ...
Disease transmission networks are key for understanding parasite epidemiology. Within the social insects, structured contact networks have been suggested to limit the spread of diseases to vulnerable members of their society, such as the queen or brood. However, even these complex social structures do not provide complete protection, as some diseases, which are transmitted by workers during brood care, can still infect the brood. Given the high rate of feeding interactions that occur in a social insect colony, larvae may act as disease transmission hubs. Here we use the bumblebee Bombus terrestris and its parasite Crithidia bombi to determine the role of brood in bumblebee disease transmission networks. Larvae that were artificially inoculated with C. bombi showed no signs of infection seven days after inoculation. However, larvae that received either an artificial inoculation or a contaminated feed from brood-caring workers were able to transmit the parasite to naive workers. These results ...
It is often said that one out of every three bites of food we eat is pollinated by a honey bee. Honeybee losses are a major problem for the beekeeping industry and potentially to agricultural commodities that depend on bees for pollination services.. The unexplained losses of managed bee colonies has been termed colony collapse disorder, and according University of Florida entomologist, Jamie Ellis, Some beekeepers in states have lost 50 to 90 percent of their colonies within a matter of weeks. But despite these high losses, the average number of colony losses has been approximately 30 percent since colony collapse disorder was first reported in 2006.. The USDA recently reported that general colony loss levels in 2009 were 29 percent and increased to 34 percent in 2010.. According to the University of Florida, colonies with CCD can appear healthy just weeks prior to collapse. However, the adult bees soon disappear from the colonies, leaving behind a box full of honey, pollen, capped brood ...
Control of vegetative forms inside the bees.. Fumagillin. This chemical has been used for many years to control Nosema in honey bees and related pathogens in other animals and in humans. It is often still effective against both Nosema apis and Nosema ceranae. However, we must consider alternatives. We cannot rely on a single type of treatment. Experienced beekeepers have seen the development of varroa mites highly resistant to chemical controls and American foulbrood bacteria resistant to antibiotics. The same problem will certainly arise with extensive use of fumagillin.. Fumagillin is produced naturally by another type of fungus called Aspergillus. Like many microbes, Aspergillus has developed its own arsenal of chemicals that help it survive.. Fumagillin treatment is prepared in sugar syrup, and fed to bees. Inside the midgut, it penetrates Nosema-infected cells. There it interferes with the Nosema genetic machinery, or with certain proteins. It does not affect the spores. After fumagillin ...
We investigated pathogens in the parasitic honeybee mite Varroa destructor using nanoLC-MS/MS (TripleTOF) and 2D-E-MS/MS proteomics approaches supplemented with affinity-chromatography to concentrate trace target proteins. Peptides were detected from the currently uncharacterized Varroa destructor Macula-like virus (VdMLV), the deformed wing virus (DWV)-complex and the acute bee paralysis virus (ABPV). Peptide alignments revealed detection of complete structural DWV-complex block VP2-VP1-VP3, VDV-1 helicase and single-amino-acid substitution A/K/Q in VP1, the ABPV structural block VP1-VP4-VP2-VP3 including uncleaved VP4/VP2, and VdMLV coat protein. Isoforms of viral structural proteins of highest abundance were localized via 2D-E. The presence of all types of capsid/coat proteins of a particular virus suggested the presence of virions in Varroa. Also, matches between the MWs of viral structural proteins on 2D-E and their theoretical MWs indicated that viruses were not digested. The ...
During 1947 the 55,000 colonies of honey bees in Utah produced approximately $545,000 worth of marketable honey and beeswax. In addition they pollinated most of the fruit, alfalfa seed, various vegetable and other seed crops. By 1949 the price of honey had declined to where the crop of honey and beeswax was worth $253,000, produced by 49,000 colonies of bees. The value of bees in Utah as pollinating agents to fruit and seed crops greatly exceeds the income received by beekeepers from bee products sold. Because agriculture receives such great benefit from bees, it seems reasonable that farmers who are deriving substantial benefit from the beekeeping industry should cooperate with beekeepers to sustain beekeeping on a sound, thriving basis.

Beekeeping, or apiculture, is the cultivation of colonies of honeybees. Commercial beekeeping includes the production of honey and beeswax, the breeding of bees for sale, and the rental of bees for pollenating crops. Beekeeping in most of the world means cultivating the western honeybee, Apis mellifera. The infamous killer bee, a relative of the African honeybee, is too aggressive for commercial beekeeping. Modern beekeeping is based on the ancient Greek technique of creating a bee space. In those days, the hive consisted of a basket of containing a series of parallel wooden bars separated by a distance equal to that between the honeycombs when they are naturally built by bees. The distance is 6.350 millimeters, or about one quarter of an inch. Any variation from this distance results in the space being filled with comb or propolis. A honeycomb is a mass of hexagonal cells in the nest that contain eggs, young bees, and honey. Lorenzo Lorraine Langstroth in 1851 brought beekeeping to the United ...
Its a tough time to be a pollinator.. Bee, butterfly, and bat populations are in decline across the globe. Even the honey bee, perhaps the best-studied pollinator, has suffered great losses as beekeepers and researchers struggle to identify the causes. In recent years, its become clear that no one factor is responsible - honey bees face an onslaught of pressures, ranging from pesticides to viruses to parasites.. A recent Journal of Economy Entomology paper puts a spotlight on just one of these problems, the honey bee pest Nosema. Summarizing decades of intensive research from across the globe, two University of Minnesota and Pennsylvania State University entomologists outline precisely why Nosema represents an intractable problem for beekeepers. Their sobering conclusion - that far more research and resources are still needed to equip beekeepers with the right tools for managing Nosema infections - throws into relief the challenge of understanding and reversing global declines not just in honey ...
The following table indicates the maximum times required for the insecticides listed in the Guide to be degraded by weather to a low hazard level for bees. These times are to be used as general guidelines only, since most of these insecticides have not been tested for bee toxicity under western Canadian conditions, and environmental conditions will influence the rate at which pesticides degrade.. Fungicides are generally not considered to have toxic effects on bees however Captan has been reported to have toxic effects on honey bee larvae. Captan is not harmful to the adult bees but can be carried back to the honey bee colony and may then have toxic effects on the brood ...
Ether rolls yield quicker results than sticky traps but can be less accurate because only a subset of the entire colony is sampled. In an ether roll, about 300 adult bees are collected in a glass jar and sprayed with ether. After the ether is added to the jar, the jar is lightly shaken for 30 seconds, during which time Varroa present on the adult bees will adhere to the inside walls of the jar, facilitating their quantification. A newer version of this sampling protocol has been developed using powdered sugar rather than ether. Once the dusted bees are shaken, the bees can be released (they are alive) and the sugar can be dumped into water. After contacting the water, the sugar dissolves, thus facilitating Varroa quantification. The sampling methods were not used very often traditionally because treatment for Varroa was recommended twice yearly, regardless of the number of mites in a colony. Recently, investigators around the world have tried to employ an integrated pest management (IPM) ...

There are several races of the honeybee. Each of these races has different advantages and disadvantages linked to their original regional background. Each region likely has a differing climate, topography, resources and predators. Because of difference in background, each race of honey bees have evolved slightly in a different manner than their cousins allowing them to better take advantage of their specific situation. Today the Italian Honey Bee is the most commonly kept honey bee in the United States, conversely the Africanized Honey Bee is the most feared and illegal to keep in many regions. Fitting somewhere between these two extremes include many of the other races and the Feral Honey Bee, though technically not a race in its own, it may be acclimated to the area in which it has been found. The following is a partial listing of the races of honeybee that may be available to a prospective beekeeper, along side is a brief amount of information regarding each race and some common advantages ...

Mika Hardison and Octavious Carr of The Herban Bee discussed honey bees impact on our world at Horticulture Corner: Oh, Honey Bee on September 7. They detailed what each of us can do to be a part of local bee conservation efforts. From urban beekeeping to creating bee sanctuaries, each of us can play a small part in ensuring the survival of this most important member of our society.. Mika Hardison is an active and knowledgeable beekeeper and the mastermind behind her popular products, including herbal honey infusions, soap, and other offerings. She specializes in urban beekeeping methods and has been actively involved in the profession since 2018. She and her husband, Octavious Carr, cofounded the The Herban Bee. As avid gardeners, they focus on integrating beekeeping into urban neighborhoods and exposing disadvantaged communities to agriculture. The couple practices their craft mostly in urban areas due to the limited land resources, a challenge many black farmers face in the United States. An ...
Honey bees are social insects that pollinate about 1/3 of the food we eat. Colony collapse disorder is a serious problem that is the biggest threat to our food sources.
By proceeding with the caveat that physiological tolerance has remained constant - species tend to be evolutionarily conservative about shifting their niches - the researchers used computer models to simulate past bee distributions based on climate conditions in the Pleistocene. The results showed that in the past, during periods when the neotropics had lowered precipitation, each species experienced significant reduction in suitable habitat, with E. cingulata maintaining the largest geographical ranges. Climate and ecological niche computer model simulations were closely matched by genetic data of the two less-tolerant orchid bee species. The genetic data included mitochondrial markers, which are only inherited from females, and nuclear markers, which come from males and females. The mitochondrial DNA showed that individual bees in one geographic area were more closely related to each other than to bees from other areas. The findings suggest the maternal lines of these bees remained in the area ...

Some of the commonly Googled questions include is honey bee vomit and is honey bee poop?, and the answer to both those questions is no. So first of all, we need to take a look into what honey really is by breaking down how it is made.. Honey bees live in colonies called hives, and they fly away from their hives to forage for pollen, propolis and nectar. The nectar is what is used to make honey, and is extracted from various flowers using the bees tongue and is stored in its crop - the honey stomach. Bees actually have not one, but two stomachs - one for eating, and another for honey. When its honey stomach is completely full, bees can almost double its weight.. When honey bees fly back to the hive, they begin to secrete enzymes that help to change the acidity and composition of the nectar to make it suitable to keep a long time. Upon its return, the forager bee will regurgitate whats in its crop, and pass it onto a house bee. This process is called trophallaxis.. House bees then process ...
The illustrations were created as part of 5 figures that highlight the anatomy, physiology, and communication behaviors of the honey bee. They will be used in Dr. Radcliffes chapter Physiology of the honey bee - principles for the beekeeper and veterinarian as part of the textbook Honey Bee Veterinary Medicine edited by Terry R. Kane, DVM and Cynthia M. Faux, DVM and published by Wiley in 2020. In 2017, the U.S. Food and Drug Administration passed a Veterinary Feed Directive (VFD) classifying honey bees as food producing animals. The VFD, along with the FDAs policy on medically important antimicrobials, requires veterinarians to oversee the healthcare and proper use of medications in apiculture. This union brings the medical education of the veterinarian together with the expertise of the beekeeper, but veterinarians have historically not received specific training in honey bees. This textbook provides additional training for veterinarians who will work with apiculturists.. ​. ...

Background: In previous studies, the gram-positive firmicute genus Paenibacillus was found with significant abundances in nests of wild solitary bees. Paenibacillus larvae is well-known for beekeepers as a severe pathogen causing the fatal honey bee disease American foulbrood, and other members of the genus are either secondary invaders of European foulbrood or considered a threat to honey bees. We thus investigated whether Paenibacillus is a common bacterium associated with various wild bees and hence poses a latent threat to honey bees visiting the same flowers. Results: We collected 202 samples from 82 individuals or nests of 13 bee species at the same location and screened each for Paenibacillus using high-throughput sequencing-based 16S metabarcoding. We then isolated the identified strain Paenibacillus MBD-MB06 from a solitary bee nest and sequenced its genome. We did find conserved toxin genes and such encoding for chitin-binding proteins, yet none specifically related to foulbrood ...
Rusy- I know this is the time of the year to check for Varroa Destroyer. I am NOT seeing anything in the hive or on the bees. I watch the bees constantly when they are coming in and out of the hive for normal wings and the presence or absence of mites, and I dont see anything abnormal. I have not done the powdered sugar test yet for this reason (I really dont know how and, dont want sugar in the hive). Should I do the sugar test or just use a preventative APIVAR or other precautionary treatment? What do you recommend?. I am currently feeding my bees at an outside feeding station which include a rack that my husband welded together with flat metal and U-bolts that holds 3 quart mason jars. The brats are getting 2:1 with honey B healthy. This is a hive that I bought locally that was a swarm that was caught in April, and I acquired in the first week of May. They have 5 frames of honey for the winter (I live in Charleston, SC). I plan to feed Bee pro mixed with fondant and honey bee healthy ...

Beyond Pesticides, January 25, 2011) Research by the U.S. Department of Agricultures (USDA) Bee Research Laboratory and Penn State University shows that the neonicotinoid insecticide imidacloprid contribute -at extremely low levels- to bee deaths and possibly colony collapse disorder (CCD), the widespread disappearance of honey bees that has killed off more than a third of commercial honey bees in the U.S. While the study has not been published yet, the UKs The Independent newspaper reports that honeybees exposed to imidacloprid are more susceptible to the fungal pathogen Nosema. This is the first study to show that neonicotinoids impact the survival of bees at levels below the level of detection, meaning that field studies would not have considered the role of the pesticide, because they would not have detected it. USDA researcher Jeffrey Pettis, PhD and Penn State University researcher Dennis Van Engelsdorp, PhD explained their research in the 2010 documentary, The Strange Disappearance of ...
Honey bees are an excellent animal to study with regards to behavior because they are abundant and familiar to most people. An animal that is disregarded every day has very specific behaviors that go unnoticed by the normal person. Karl von Frisch studied the behavior of honey bees with regards to communication and was awarded the Nobel Prize for physiology and medicine in 1973. Von Frisch noticed that honey bees communicate with the language of dance. Honey bees are able to direct other bees to food sources through the round dance and the waggle dance. The round dance tells the other foragers that food is within 50 meters of the hive, but it does not provide much information regarding direction. The waggle dance, which may be vertical or horizontal, provides more detail about both the distance and the direction of the located food source. It is also hypothesized that the bees rely on their olfactory sense to help locate the food source once the foragers are given directions from the dances. ...
Abstract: Alcohol consumption increases apoptosis of hepatocytes. Death of hepatocytes is a characteristic feature of chronic liver disease for various causes. Bee venom (Apis mellifera) has been traditionally used for the treatment of various chronic diseases, such as chronic inflammatory arthritis and chronic liver disease. However, the precise mechanism for bee venom in chronic liver disease is not still cleared. To assess the effects of bee venom in chronic liver disease, we investigated the potential role of the bee venom in the ethanol-induced hepatocyte apoptosis. Bee venom treatment inhibited the apoptotic cell morphology and increased the cell viability in ethanol-induced hepatocyte apoptosis. With ethanol treatment, bee venom-treated hepatocytes increased activity of Bcl-2 and Bcl-xL, reduced activity of Bax, Caspase and PARP. In conclusion, bee venom treatment in ethanol-induced hepatocyte apoptosis occurred through the regulation of Bcl family with subsequent inactivation of the ...

The D1/D2 sequence of the type strain differs from that of the most closely related species, Wickerhamiella domercqiae, by 57 substitutions and three gaps. Bumblebees (or Bumble bees, or Humble bees) are a group of social and semi-social bees, of the genus Bombus.The genus contains about 250 different species, mostly in the Northern Hemisphere.They can also be found in New Zealand and Tasmania.They occur practically everywhere on the Eurasian landmass. When a colony attains a population of about a few dozen adult worker bees, the colony enters the reproductive stage. B. terrestris is the most intensely studied non- Apis bee. Occasionally the colonies are convoluted with a lobate edge. The European Bumble Bees, Bombus terrestris, feral in Tasmania, are large, fat and very hairy. Then an inexperienced observer bee was introduced to the arena. They can be found in the Eastern temperate forest region of the eastern United States, ...

Varroa destructor mites pose an increasing global threat to the apicultural industry and agricultural ecology; however, the issue of whether certain environmental factors reflect the level of mite infection is far from resolved. Here, a wireless sensor network (WSN) system was used to examine how V. destructor, which has vital impacts on honeybee (Apis mellifera) health and survival, affects the temperature and humidity of honeybee hives in a field experiment. This approach may facilitate early identification of V.

  • For example, numbers of the Western honeybee-the most common of the domesticated species-in the United States have actually been rising slowly in recent years (there around 2.9 million colonies today compared with 2.5 million colonies 10 years ago, according to data from the U.S. Department of Agriculture), and the species is not at risk of extinction. (
  • Large-scale losses of honey bee colonies represent a poorly understood problem of global importance. (
  • Everyone wants healthy, thriving honey bee colonies. (
  • Managed honey bee colonies are our primary pollinators, adding at least $15 billion a year by increasing yields and helping to ensure superior-quality harvests. (

  • The "heater bees" have been found to play a crucial, and previously unappreciated, role in the survival of honey bee colonies. (
  • Most of the parasites in the wild bumblebees were found to be at normal levels except for one intestinal parasite known as Crithidia bombi that is common in commercial bee colonies but typically absent in wild bumblebees. (
  • The "spillover" of disease from commercial colonies may be a factor in the decline of bee populations in North America, he added. (
  • LONDON (Reuters) - England's honey bee colonies are dying at an alarming rate due to disease and a lack of coordinated response by health authorities, a parliamentary report concluded on Tuesday. (
  • England and Wales have around 250,000 colonies of honey bees, which contribute around 200 million pounds to the economy since they are solely responsible for pollinating nearly 40 commercial crops. (
  • As well as changes to habitat and food supply, the bees were being adversely affected by cold and weather, with the threat that up to 30 percent of colonies could be lost over the winter. (
  • Transport of bee colonies and bee products (e.g. beeswax) across international boundaries can pose a risk of accidental introduction of insects, fungi or other potentially destructive agents. (
  • It is recommended that anyone planning to move bee colonies across international boundaries check with appropriate authorities in the country from where the products are to be exported and the countries into which the products are to be imported for import permit requirements, sanitary certificates or restrictions that might apply. (
  • By mating with nearly 100 males, queen bees on isolated islands avoid inbreeding and keep colonies healthy. (
  • The results, published in the current issue of PLoS ONE, focused on giant honey bee colonies on Hainan Island, off the coast of China. (

  • Experts urge that no one other than trained beekeepers maintaining colonies during a dearth of nectar should provide bees with sugar water. (
  • Colonies without pollen supply maintain brood rearing only for a short time, first by using up the stored bee bread and later by depleting their body reserves. (
  • In North America and Europe, Colony Collapse Disorder, a poorly understood phenomenon that causes worker bees to abandon and therefore destroy their colonies, became an increasing concern in the early 2000s, stoking fears over pesticide use and the future of farming. (
  • To pare down these potential culprits, Reed Johnson from the University of Illinois compared the genetic activity of bees from over 120 colonies, including some affected by CCD and healthy ones that were sampled before the vanishing began. (
  • Indeed, although Johnson found that no single infection separated the CCD colonies from the healthy ones, the sick bees were generally carrying a higher burden of viruses and parasites. (
  • Since ~2006, honey bee colonies in the US have been dropping dead overnight. (
  • The bees were then removed and a second group of flowers were added to the foraging arena along with colonies of a second bee species (a species not used before). (
  • There are millions of honey bee colonies in North America, 2.8 million of which are in the U.S. Approximating around 30,000 bees per colony (the size of a pollination unit ), that's roughly a billion honey bees in Canada and the U.S. alone-almost triple the number of people. (
  • High densities of honey bee colonies increase competition between native pollinators for forage, putting even more pressure on the wild species that are already in decline. (
  • In the highlands of the islands' Teide National Park, thousands of honey bee colonies are introduced seasonally for honey production and removed again at the end of the nectar flow, creating an excellent scenario for experimentation. (
  • Wild colonies would be of the UK's native honey bee subspecies Apis mellifera mellifera, also known as the European dark bee, surviving on their own in remote areas or in a range of cavities. (
  • It has been suggested that disease wiped them out in the early 20th Century, yet across most parts of the UK there remain anecdotal sightings of colonies thriving without human intervention. (
  • The author concluded that there are unlikely to be any large, remote colonies of wild honey bees remaining in England and Wales and, as a result, she turned her attention to feral honey bees - colonies living in the wild that are thought to have escaped from managed stocks. (
  • To discover their significance Dr Thompson asked bee keepers to report unmanaged colonies of bees that had lasted for at least a year near to them. (
  • She sampled bees from feral colonies along with those from managed colonies in the same area. (
  • Dr Thompson found that the feral and non-treated managed colonies had a significantly higher level of Deformed Wing Virus (DWV), which is transmitted to bees by the varroa mite, than the managed colonies that were treated. (
  • If not in beekeepers' hives, then in wild bee colonies. (
  • Albeit that those colonies may at first have been escapees, they cannot all have died out or we would not have the varroa tolerant bees we now see. (
  • He and his colleagues established 38 bee colonies across central California, ranging from undisturbed chaparral to organic and conventional farms. (
  • Therefore, a mosaic landscape that has natural areas mixed in with agriculture is important to keep bee colonies healthy. (
  • Bee colonies feature highly efficient social structures. (
  • In honey bee colonies tasks are divided according to age. (
  • Because beets are incredibly nutritious and pollinated by the wind, they are one of the staple crops that scientists believe we would be forced to eat regularly if bee colonies completely collapse. (
  • But the steady decline of bee colonies puts these foods and drinks in jeopardy. (
  • Thirty to 40 percent of all bee colonies are lost every season, beekeepers report. (

  • Researchers who led the Canadian study concluded that worker bees exposed to neonicotinoids - which they said often came from contaminated pollen from nearby plants, not from treated crops - had lower life expectancies and their colonies were more likely to suffer from a loss of queen bees. (
  • On the findings of the European study, researchers told a briefing in London that exposure to neonicotinoid crops harmed honeybee colonies in two of the three countries and reduced the reproductive success of wild bees across all three. (
  • The Bee Research Lab conducts research to improve the health of honey bee colonies and help the beekeeping industry maintain an adequate healthy supply of bees for the pollination of crops. (
  • When a bee comes in contact with pesticides while foraging, the bee may die immediately without returning to the hive. (
  • Colony collapse disorder is a syndrome that is characterized by the sudden loss of adult bees from the hive. (
  • The queens daily laying rate will decline if contaminated materials are brought back to the hive such as pesticides.31.6% of exposed honey bees will fail to return to their colony every day while the rest will bring back contaminated pollen which in turn will not only affect the worker bees but also the queen. (
  • There is only one queen in a hive and her main purpose is to make more bees. (
  • Worker bees are the most numerous in the hive and do all the different jobs needed to maintain and operate the hive. (
  • When they are young they are called house bees and work in the hive doing comb construction, taking care of young bees, tending the queen and drones, cleaning temperature regulation and defending the hive. (

  • By herself one honey bee can produce 1/12 of a teaspoon of honey over its lifetime, while a hive can generate over 80 pounds of honey in a matter of months" Bonner shared. (
  • This is probably because a bee that lives alone in a hole in the desert has less to defend than a social honeybee that has invested all its energy in helping to maintain a hive for 50,000 of its brethren. (
  • I certainly wouldn't suggest to anyone that you import Africanized bees as a method to combat varroa… If you've got resistance to varroa, that's great, but if I get 10,000 stings every time I open a hive that's no good. (
  • By contrast, an average honeybee hive at the height of summer will have 30,000 - 50,000 bees. (
  • Except for her one mating flight or to establish a new colony, the queen rarely leaves the hive after the larvae have become full grown bees. (
  • Worker bees are infertile females which secrete the wax used to build the hive, clean and maintain the hive, raise the young, guard the hive and forage for nectar and pollen. (
  • In honeybees, the worker bees have a modified ovipositor called a stinger with which they can sting to defend the hive, but the bee will die soon after. (
  • If you want to get rid of an entire bee hive or wasp nest, it is usually best to call a professional exterminator so that you do not put yourself at risk for getting attacked by a swarm of bees. (
  • If you are going to attempt to cut down a bee hive yourself, you should always wear protective gloves, glasses or goggles and a long sleeved shirt. (
  • Using new technology that allows sceintists to see the temperature inside the bee hives, researchers have been able to see how heater bees use their own bodies to provide a unique form of central heating within a hive. (
  • They have found that these specialised bees, whose body temperatures are considerably higher than other bees in the colony, not only keep the hive warm but also control the social make-up within a colony. (
  • Heater bees are responsible for maintaining the temperature of the brood nest in a hive, where young bees, known as pupae, are sealed into wax cells while they develop into mature bees. (
  • The heater bees, which can number from just a few to many hundreds depending on the outside temperature and size of the hive, also press themselves against individual cells to top up the temperature of each pupae to ensure it develops into the right kind of bee. (
  • Rather than try to clear the bees from the jet themselves, crew members realized that honey bees are at risk of extinction and contacted local beekeeper and retired US Navy veteran, Andy Westrich, who proclaimed the hive the largest he had ever seen after being escorted to the aircraft. (
  • Before transporting the bees to their new home at a local beer production facility, Westrich took them to his house and found that the hive weighed nearly eight pounds in total, according to the Air Force release. (
  • They likely came from a much larger bee hive somewhere else on the base, according to Chief Master Sgt. (
  • The University of Dundee study will investigate whether certain pesticides damage the nervous systems of bees and stop them being able to do the "waggle dance" which shows the rest of the hive where a food source is located. (
  • I've kept bees for 18 years now - started with 1 hive , now have 3 goodun's and 2 'iffey' ones and I'm thinking this year's been the. (
  • Bees can become tired and they simply don't have enough energy to return to the hive which can often result in being swept away. (
  • The calls act as an instinctive warning to leave the hive, but the frequency confuses the bees, causing them to fly erratically. (
  • In the past few years when I've been investigating hive thefts, it's been 20 here, 40 there. (
  • There are different types of bees in a honey bee hive: Worker, Drone and Queen. (
  • This mixture of chemicals is passed individually from bee to bee throughout the entire hive as they share food. (
  • For the first two to three weeks of adult life, bees typically take care of the brood in the hive. (
  • The bold bee scouts that go out in search of food for their hive show more activity in certain genes in their brains than do other bees. (
  • They go out and find new sources of food without being directed to those sources, while the non-scouts wait in the hive until they are recruited by a scouter bee ,' study researcher Gene Robinson, director of the Institute for Genomic Biology at the University of Illinois at Urbana-Champaign, told LiveScience. (
  • The bees can leave the building, but they cannot get back in and will settle in the decoy hive. (
  • Remove the trap and allow the bees in the decoy hive to go back in the building to retrieve their honey. (
  • When they get the chance, the larvae then grab on to the female bee and catch a ride to the inside of the hive where they can feed on young bees and honey. (
  • Recent attack victims include several people in La Mesa, CA who were swarmed by Africanized bees, and a Las Vegas man who was stung some 2,000 times after he overturned a rock that exposed a 50 lb. hive. (
  • Bees set up hive in professor's cello Jump to media player A university professor has used the cello to research vibrations made by the pollinating insects. (
  • During 30 minutes of collection time a well adjusted collector device will not kill more than 10 bees per hive. (
  • This loss is not significant to the population of the bee hive and does not eff ect the life span of the colony. (
  • Bees pollinate a significant majority of the world's food, but they are disappearing at an alarming rate. (
  • Native to Europe, Asia, and Africa, the honey bee is a single species of bee that happens to be easily domesticated, not only for honey production at but also to pollinate crops. (
  • One-third of the food we eat requires pollinators, and commercial beekeepers transport honey bees hundreds of miles each year to pollinate almond trees and other crops. (
  • Honey bees may be in different hives, but they pollinate and work together. (
  • Bees land on the sunflowers to pollinate. (
  • Bees pollinate numerous crops, and scientists have been expressing alarm over their falling numbers in recent years in North America. (
  • She said crops like strawberries need wild flowers nearby to maintain a population of bees and other insects to pollinate the fruit in summer. (
  • These bees, which were imported to North America to pollinate agricultural crops, are easy to distinguish from native bees by their coloring, which is golden brown with black abdominal stripes. (
  • Honeybees pollinate a wide range of plants, including important agricultural crops like almonds, although they're often less efficient than native bees. (
  • Roughly one out of every three or four bites we take is due to the busy little bees that pollinate our fruits and vegetables. (
  • Hives of these bees are trucked cross-country to pollinate oranges in Florida, apples in Pennsylvania, blueberries in Maine. (
  • Meanwhile, researchers have developed a new appreciation for the hundreds of species of wild bees that also pollinate our plants. (
  • While large populations of organisms dying is disturbing, no matter the species, we need honey bees-- they help pollinate so many of our crops. (
  • Gratitude, however, doesn't begin to cover what we owe to bees collectively: they pollinate 70 of the top 100 food crops humans cultivate, supplying 90% of our nutrition world-wide. (
  • Honey bees produce millions of dollars worth of honey and beeswax, as well as pollinate commercial fruits, vegetables, and field crops that we depend on for food. (
  • Examples of management of non- Apis species for agricultural pollination include the use of bumble bees, primarily for the pollination of greenhouse tomatoes, the solitary bees Nomia and Osmia for the pollination of orchard crops, Megachile for alfalfa pollination, and social stingless bees to pollinate coffee and other crops [ 9 - 12 ]. (
  • This is a scary trend because bees pollinate one in three of all the foods we eat. (
  • Thursday's feast exemplifies our reliance on bees, as they pollinate the ingredients of many classic Thanksgiving dishes: Brussels sprouts, mashed potatoes, green beans, pumpkin pie, and more! (
  • There is no doubt that bees and the flowers that they pollinate evolved simultaneously . (
  • But honeybees are really only one of a group of insects that includes other bees, wasps, and ants. (
  • By focusing attention on honeybees, policies and funding priorities may undermine native bee conservation and have negative impacts, ecologically and socially. (

  • This initiative will help some of our world-class researchers to identify why bee numbers are declining, and that will help us to take the right action to help," he said. (
  • By using this technique, the researchers hoped to overcome the bees' intrinsic responses to sucrose and quinine and test only their judgment of the new smells. (
  • RIVERSIDE, Calif. - Despite their beauty, flowers can pose a grave danger to bees by providing a platform of parasites to visiting bees, a team of researchers has determined. (
  • Alfredo Valido and Pedro Jordano, researchers from the Spanish National Research Council in Tenerife and Sevilla, respectively, saw an opportunity to use these islands-a Spanish archipelago off the northwestern coast of Africa-to study how the introduction of honey bees affects the native pollinating community. (
  • The researchers believe that the rumbles alert both the elephant's family and neighbouring herds to the threat, and may teach young elephants that bees are dangerous. (
  • Next, the researchers saddled more than 900 bees in tiny harnesses and puffed a whiff of fragrance in their faces just before feeding them a sugar solution laced with different doses of caffeine. (
  • The researchers inspiration: honey bees. (
  • The researchers watched bees discover new food sources and those seen visiting a new food sources at least twice were tagged as scouts. (
  • The researchers wanted to see if mucking with these pathways could change the bee's behavior , so they gave the bees drugs that turned up or down the levels of these brain chemicals. (
  • The researchers found evidence of increased wild bee population extinction rates in response to neonicotinoid seed treatment. (
  • A team of researchers bombarded honey bees with floral smells paired with sugary rewards, some of which contained the same levels of caffeine found in the nectar of coffee and citrus flowers. (
  • When the researchers applied the stimulant directly to honey bee brains, it had a positive effect on the neurons associated with the formation of long term memories. (
  • The life cycle of bumblebee begins in the spring when the queen bee rises from hibernation. (
  • In this case, the queen bee , brood, and nurse bees are not contaminated and the colony survives. (
  • Each female bee creates a series of provisioned brood cells in a gallery. (
  • Each bee in a colony performs a different profession - there are guard bees, nest building bees, brood caretaking bee, queen caretaking bee and forager bees, which are the ones we are familiar with as they leave the colony. (
  • They then crawl into empty cells within the brood nest, transmitting heat to the surrounding cells where the bee pupae are developing. (
  • This honey bee immunosuppression is similarly induced by a different neonicotinoid, imidacloprid, but not by the organophosphate chlorpyriphos, which does not affect NF-κB signaling. (
  • Millions and millions of bees and other life-sustaining insect pollinators are being killed-off by neonicotinoid pesticides. (
  • The Sierra Club of Canada is doing everything it can to raise public awareness of its #SaveTheBees campaign -- it won't stop until it wins a ban on bee-killing neonicotinoid pesticides. (
  • I want to ask you to join Sierra Club Canada in taking the next step to convince government to ban bee-killing neonicotinoid pesticides. (
  • But crop chemical companies say real-world evidence is not there to blame a global plunge in bee numbers in recent years on neonicotinoid pesticides alone. (
  • Ben-Shahar didn't set out to discover the effect of manganese on bee behavior. (
  • When a honey bee detects sugar, it reflexively extends its proboscis, a stereotyped behavior that can be experimentally manipulated and quantified. (
  • Now, they want to see if bees go out of their way to feed on caffeinated nectar, perhaps even ignoring predators to do so-behavior that, if observed, could shed light on the neurological processes behind addiction. (
  • Honey bees hanging from the exhaust nozzle of an F-22 Raptor engine on June 11, 2016 at Joint Base Langley-Eustis, Virginia. (
  • Tracheal mites, Acarapis woodi, are parasites that pose a significant health problem for honey bees in the United States and in many other countries. (
  • Multiple viral infections could lead to CCD, via an inability to produce new proteins that renders bees susceptible to pesticides, parasites and other threats. (
  • The study, published online in the Proceedings of the Royal Society B , is the first to show that not only can bees disperse parasites around the environment but also that flowers are platforms for a host of pollinator parasites subsequently dispersed onto visiting bees. (
  • Parasites found in the new group of flowers confirmed the non-target bee was able to disperse the parasites. (
  • Their sole function is to mate with the queen bee. (
  • A queen bee can live for up to five years, but her period of usefulness rarely exceeds two or three years. (
  • If a queen bee is removed from a colony, the workers will notice her absence within several hours because of the drop in the level of this pheromone. (
  • Some solitary bees make chimneys or turrets at the nest entrance, others nest in wood or in the pith of twigs or canes. (
  • In most orchards, It's either feast or famine for O. lignaria-not very healthy for a bee that doesn't typically prefer traveling far distances. (
  • The female bees typically mate with several male bees to collect all the sperm need. (
  • This is to say, fear-mongering about imminent ecological collapse owing to declines in the honey bee population are rather over-wrought. (
