The eusocial Hymenoptera have radiated across a wide range of thermal environments, exposing them to significant physiological stressors. We reconstructed the evolutionary history of three families of Heat Shock Proteins (Hsp90, Hsp70, Hsp40), the primary molecular chaperones protecting against thermal damage, across 12 Hymenopteran species and four other insect orders. We also predicted and tested for thermal inducibility of eight Hsps from the presence of cis-regulatory heat shock elements (HSEs). We tested whether Hsp induction patterns in ants were associated with different thermal environments. We found evidence for duplications, losses, and cis-regulatory changes in two of the three gene families. One member of the Hsp90 gene family, hsp83, duplicated basally in the Hymenoptera, with shifts in HSE motifs in the novel copy. Both copies were retained in bees, but ants retained only the novel HSE copy. For Hsp70, Hymenoptera lack the primary heat-inducible orthologue from Drosophila melanogaster and
The first identification of a sex pheromone of a pine sawfly (Hymenoptera, Diprionidae) dates back almost thirty years. Since then, female-produced pheromones of over twenty diprionid species have been investigated by solvent extraction followed by separation and identification. However, no study has shown what the females actually release. Collection of airborne compounds using absorbtion on charcoal filter as well as solid phase microextraction (SPME) followed by analysis employing gas chromatography combined with mass spectrometry (GC-MS), revealed an unusual system in Diprion pini, in which the pheromone precursor alcohol, 3,7-dimethyl-2-tridecanol, is released together with acetic, propionic, butyric and isobutyric acids. The corresponding acetate, propionate and butyrate esters of 3,7-dimethyl-2-tridecanol were also found in the samples. All esters were electrophysiologically active, and the propionate and isobutyrate were attractive in trapping experiments. Based on these and earlier ...

Most sawflies (Symphyta) are plant feeders and many species are pest insects in agriculture or forestry. Every year the larvae of diprionids (conifer or pine sawflies) defoliate large areas of conifer forests in Europe, Asia and North America. The most important effect of pine sawfly defoliation is reduced growth of the trees. In some areas chemical insecticides are used to reduce populations and damage. The general biology and distribution of these species are usually well known, whereas the chemical ecology of sawflies is less known, with exception of the family Diprionidae.. Within this project we attempt to characterize pheromones of different sawfly species, and so far emphasis has been on diprionid species. We also investigate the possibility to use pheromones for monitoring and control of sawflies. Until now the following diprionid species have been studied within the project: Diprion jingyuanensis, D. pini, D. similis, Gilpinia frutetorum, G. pallida, G. socia, Macrodiprion nemoralis, ...

The taxonomy of the ichneumonids is still poorly known. The family is highly diverse, containing 24,000 described species. Approximately 60,000 species are estimated to exist worldwide, though some estimates place this number at over 100,000. They are severely undersampled, and studies of their diversity typically produce very high numbers of species which are represented by only a single individual.[19][20] Due to the high diversity, the existence of numerous small and hard to identify species, and the majority of species being undiscovered, it has proven difficult to resolve the phylogeny of the ichneumonids. Even the relationships between subfamilies are unclear. The sheer diversity also means DNA sequence data is only available for a tiny fraction of the species, and detailed cladistic studies require major computing capacity. Extensive catalogues of the ichneumonids include those by Aubert,[9][10][11] Gauld,[21] Perkins,[12][13] and Townes.[14][22][23][24][25] Due to the taxonomic ...
Two sawfly species that feed on white fir were studied in Modoc County, California: Neodiprion near deleoni Ross and N. abietis complex. Neodiprion near deleoni comprised 91 percent of the field Neodiprion populations and spun opaque brown cocoons in the litter or soil. Neodiprion abietis accounted for 9 percent of the field population and spun translucent cocoons that appear green and are attached to foliage. Full-grown larvae, pupae, and adults of the two strains were morophologically distinct, though eggs and young larvae were not. Differences in morphology, phenology, physiology, and behavior are described for the two species. Mortality factors are identified, primarily for N. near deleoni. Parasitoids emerged from eggs and cocoons; many parasitoids that emerge from cocoons attack larvae. Larval predation was observed only rarely, except for predation by theridiid spiders. Sampled cocoons showed: 16 to 21 percent parasitized
Sawflies make up the suborder Symphyta, a group of largely herbivorous insects in the order Hymenoptera. This group is an artificial assemblage of superfamilies that are essentially the most primitive taxa within the Hymenoptera (some going back 200 million years). Sawflies are distinguishable from most other Hymenoptera by the broad connection between the abdomen and the thorax (see image), and the caterpillar-like larvae (below). The common name comes from the appearance of the ovipositor, which looks much like the blade of a saw. This ovipositor, which is modified into a stinger in some members of the Apocrita, is not used as a weapon. Females use the ovipositor to cut into plants where they lay their eggs. A few species have long thin ovipositors used to drill holes deep into wood. Large populations can cause economic damage in cultivated areas and forests. The larvae look like caterpillars (the larvae of moths and butterflies), with two notable exceptions; (1) they have five or more ...
The fall armyworm, Spodoptera frugiperda, a moth originating from tropical and subtropical America, has recently become a serious pest of cereals in sub-Saharan Africa. Biological control offers an economically and environmentally safer alternative to synthetic insecticides that are being used for the management of this pest. Consequently, various biological control options are being considered, including the introduction of Telenomus remus, the main egg parasitoid of S. frugiperda in the Americas, where it is already used in augmentative biological control programmes. During surveys in South, West, and East Africa, parasitized egg masses of S. frugiperda were collected, and the emerged parasitoids were identified through morphological observations and molecular analyses as T. remus. The presence of T. remus in Africa in at least five countries provides a great opportunity to develop augmentative biological control methods and register the parasitoid against S. frugiperda. Surveys should be carried out
article{7fbbd565-b530-4a67-9457-94160ef86600, abstract = {Males of the European pine sawfly, Neodiprion sertifer Geoffr., were marked and released downwind from pheromone traps, baited with 100 mug of the sex pheromone (2S,3S,7S)-3,7-dimethyl-2-pentadecyl acetate. Males were released 5 m downwind from one trap, or downwind from five traps, 50 m or 200 m away. The average capture rates after 24 hr were 21.5%, 17.7% and 3.8%, respectively. The capture rate was highest at moderate wind speeds (1-2 m/sec) in the 50 m experiments, whereas it decreased above wind speeds of 1.5 m/sec in the 200 m experiments. With no precipitation and > 13.5 degreesC during overcast, wind speed is presumably the most important climatic factor for N. sertifer males flying upwind to a pheromone source. Travel time, the elapsed time form take-off to landing on the trap, varied considerably, and the shortest recorded travel times were 1, 6 and 45 min for the 5, 50, and 200 m experiments, respectively. The trap ...
Karyotypes of eleven parasitoid species of the family Eulophidae were examined, namely, Chrysocharis laomedon (Walker, 1839) (2n = 10), Chrysocharis sp. aff. laomedon (n = 5, 2n = 10), Chrysocharis sp. aff. albipes (Ashmead, 1904) (2n = 12), Mischotetrastichus petiolatus (Erdös, 1961) (n = 6, 2n = 12), Minotetrastichus frontalis (Nees, 1834) (n = 5, 2n = 10), Cirrospilus pictus (Nees, 1834) (2n = 12), Hyssopus geniculatus (Hartig, 1838) (2n = 16), Sympiesis gordius (Walker, 1839) (2n = 12), S. sericeicornis (Nees, 1834) (2n = 12), Pnigalio agraules (Walker, 1839) (2n = 12 + 0-2B) and Pnigalio gyamiensis Myartseva & Kurashev, 1990 (2n = 12 + 0-6B) reared from Phyllonorycter acerifoliella (Zeller, 1839), Ph. apparella (Herrich-Schäffer, 1855), Ph. issikii (Kumata, 1963) (Gracillariidae) and Chrysoesthia sexguttella (Thunberg, 1794) (Gelechiidae).

Alien parasitic wasps, including accidental introductions and purposefully released biological control agents, have been implicated in the decline of native Hawaiian Lepidoptera. Understanding the potential impacts of alien wasps requires knowledge of ecological parameters that influence parasitism rates for species in their new environment. Sophora seed-feeding Cydia spp. (Lepidoptera: Tortricidae) were surveyed for larval parasitoids to determine how native and alien wasps are partitioned over an elevation gradient (2200-2800 m) on Hawaii Island, Hawaii. Parasitism rate of native Euderus metallicus (Eulophidae) increased with increased elevation, while parasitism rate by immigrant Calliephialtes grapholithae (Ichneumonidae) decreased. Parasitism by Pristomerus hawaiiensis (Ichneumonidae), origins uncertain, also decreased with increased elevation. Two other species, Diadegma blackburni (Ichneumonidae), origins uncertain, and Brasema cushmani (Eupelmidae), a purposefully introduced biological control

Field and laboratory studies were conducted to determine how Apanteles scutellaris and Agathis gibbosa (Hymenoptera: Braconidae) coexist as solitary endophagous parasitoids of potato tuberworm (PTW) larvae, Phthorimaea opercullela (Lepidoptera: Gelechiidae), in southern California. The competitive characteristics of Orgilus jennieae (Hymenoptera: Braconidae), an exotic parasitoid of PTW larvae, were compared with those of the native species to determine its potential for establishment. Emergence of the egg-larval parasitoid Chelonus phthorimaeae (Hymenoptera: Braconidae) from field-collected PTW larvae was compared with those of the other parasitoids, but its competitive interactions were not considered. Seasonal density changes, mine characteristics, and within-plant distributions of PTW larvae were studied to determine their possible impacts on parasitoid interactions.

Hefei City, Anhui Province, China, July 9, 2020.- PHOTOGRAPH BY Costfoto / Barcroft Studios / Future Publishing. Adults are actually wasps. While butterfly and moth caterpillars have 2 to 5 pairs of fleshy prolegs on the abdomen; sawflies have more than 5 pairs. These larvae feed and cause damage on many kinds of ornamentals and fruit trees, including cherry, cotoneaster, mountain-ash, pear, purple leaf plum and serviceberry. Low impact pesticides. Cimbex connatus. In the tradition of the worlds great dynasties, centuries of breeding and pampering have established roses (Rosa spp.) The larvae hatch quite quickly and move in a group to the freshly emerged leaves. About a week after, both were infested with what appears to have been the pamphillidae-ancantholyda sp. Sawfly Larvae Look Like Caterpillars . Similar Images .

We lightened up your lateral view and we conclude this is not a Caterpillar. There are ten legs visible, three true legs and seven prolegs, and because insects have bilateral symmetry, we can deduce that there are seven pairs of prolegs. Most caterpillars have five pairs of prolegs, though caterpillars from the Inchworm family Geometridae have but two pairs of prolegs. This is the larva of a Sawfly, and though it really resembles members of the genus Cimbex, including the Elm Sawfly, we have never seen such coloration that we can recall. Perhaps one of our readers will recognize this Sawfly.. ...
Chewing large holes, or entire leaf blades is another, less-common sawfly. The larvae of Megaxyela major (Cresson) is yellow in color with prominent black spots and a black head capsule. Larvae grow to 3/4 inch long before dropping to the ground and pupating. This sawfly has the curious habit of curling around a leafs rachis or midrib during daylight hours (photo at right). As night falls, the larvae continue to feed on entire leaves often leaving just the midrib. We have never had a serious outbreak of this sawfly species ...
Ash sawfly definition is - any of various sawflies (especially Tomostethus multicinctus and Tethida cordigera) having larvae that feed on and defoliate ash trees.
Use Trichogramma spp., a moth egg parasite that prevents caterpillars from emerging by laying their eggs in the moth eggs, killing them. Timing the release is important - if you release too early there arent enough pest eggs for the wasps to parasitize - too late means that the pest eggs have hatched and you have a new problem - caterpillar pests. Biology & Life Cycle: Trichogramma wasps lay their eggs inside the pest eggs, stopping development. The larvae feed on the egg and then emerge as adults. The larvae take 10 days to develop within the pest moth egg, which turns brown or black as the larvae pupate. The adult wasps live anywhere from 7 to 14 days, depending on temperature and moisture and the female Trichogramma will parasitize up to 300 pest moth eggs. Eggs on cards usually hatch within 2-5 days. Preferred food: Trichogramma parasitize the eggs of more than 200 pests, including borers, webworms, loopers, leafworms, fruitworms, cutworms, bollworms, and armyworms (except beet armyworms).

VIT is globally accepted as the treatment of choice in venom allergy.15. Although 44 patients in the current study declared a negative effect of VIT on work, caused by changing working time and economic loss due to VIT, most of our participants declared an indifferent effect of VIT on work. Individuals at high risk of sting reported a positive VIT impact on work. This will support the accepted medical approach that occupation may influence the decision to initiate VIT, also for non-life-threatening reactions.5. Another predictor of a perceived positive effect from VIT was completion of treatment. Participants who have already completed VIT are probably more aware of the long-term beneficial effects of treatment. They are less likely to report any drawbacks of VIT, such as the time spent in therapy, which can affect work and social life. A relevant number of participants reported a negative impact of VIT on work and even if we could not find any peculiar characteristic of this group, this finding ...

The HYMENOPTERA class of insects are the only stinging insects. However only a few of the hymenoptera (honeybees, wasps, hornets, yellow jackets and fire ants) cause serious allergic reactions. Overall, the yellow jacket is the most common offender followed by honey bees, wasp and then hornets. Bumblebees rarely sting humans. The base of the stinger of hymenoptera insects is attached to a small venom filled sac. Most stinging insects except the honeybees can reuse their stingers, inflicting multiple venom injections. In contrast, the honeybees stinger is barbed so when it tries to remove its stinger from the skin, both the stinger and venom sacs are torn off and left in the victim. Most hymenoptera actually use their stingers in self defense, for defense of the hive or for killing other insects ...

Figure 3. In general, larvae complete feeding by the time needles emerge from the candelabra. Therefore, those needles are not damaged. There really is only a minor threat of branch or tree death resulting from sawfly larval feeding. However, the loss of second- and third-year needles may be noticeable in landscape trees and ruin their appearance. In late spring, the larvae drop to the ground and pupate in brown, leathery cocoons at the base of trees. Wasp-like adults emerge in fall and lay eggs in the needles before winter. There is one generation per year in Kansas.. Although sawfly larvae look-like caterpillars; they are not caterpillars (Order: Lepidoptera) as they are related to ants, bees, and wasps (Order: Hymenoptera). The best way to tell a sawfly larva from a caterpillar is by the following: 1) sawfly larva have prolegs on every abdominal segment whereas caterpillars are missing prolegs on the abdomen and 2) caterpillar larva have hairs or crochets on their feet whereas sawfly larva do ...

Juvenile sawfly larvae can appear in several different forms, depending on the variety. Often, they will look like small slug or worm. They feed on the soft tissue of leaves and on evergreens, consumeing the new needles. In a few cases, the sawfly larvae act as leafminers, living and eating within the leaf, never emerging outside of the leaf. The leafminer version is more difficult to control than the exposed juveniles, because being inside the leaf protects them.. ...

Spalangia cameroni Perkins (Hymenoptera: Pteromalidae) is a pupal parasitoid of the Medfly, Ceratitis capitata (Wiedmann) (Diptera: Tephritidae), one of the principal pests of Spanish agriculture. Spalangia cameroni is a potential biocontrol agent for this pest if methods can be developed to mass-rear it effectively on C. capitata. Here, we report on the use of freeze-killed pupae of C. capitata to maintain a laboratory colony of S. cameroni, with a view to setting up a mass-rearing protocol. Realised fecundity, adult progeny, sex ratio, and superparasitism level were the principal parameters analysed. No significant differences were found in respect of these parameters between living or freeze-killedMedfly pupae used as hosts, although sex ratios showed a bias towards females in the case of freeze-killed pupae. Freeze-killed pupae were concluded to present the best option for the laboratory-rearing of S. cameroni, on account of ease of rearing, and avoidance of the emergence of Medfly adults ...
The evolution of eusociality occurred repeatedly in different orders of animals, particularly the hymenoptera (the wasps, bees, and ants). This true sociality in animals, in which sterile individuals work to further the reproductive success of others, is found in termites, ambrosia beetles, gall-dwelling aphids, thrips, marine sponge-dwelling shrimp (Synalpheus regalis), naked mole-rats (Heterocephalus glaber), and the insect order Hymenoptera (which includes bees, wasps, and ants). The fact that this behavior has evolved so many times in the hymenoptera (between 8 and 11 times ), but remains rare throughout the rest of the animal kingdom, has made the evolution of eusociality a topic of debate among evolutionary biologists. Eusocial organisms at first appear to behave in stark contrast with simple interpretations of Darwinian evolution: passing on ones genes to the next generation, or fitness, is a central idea in evolutionary biology. Current theories propose that the evolution of ...

With yellow jackets it is sometimes difficult to determine whether you should like them or not. On one hand, they can result in severe discomfort when you accidentally disturb a nest, and the workers swarm and in the process of defending their hives they attack you. On the other hand, yellow jackets are voracious predators of plant-feeding herbivores such as caterpillars, beetles and other pests. Yellow jackets contribute toward the reduction of pest populations.. Yellow jackets are wasps in the family Vespidae. There are many species of yellow jackets in North America. One of the more common in our area is the Eastern yellow jacket. Colonies can be underground, in dense shrubs or vegetation, or in human-made structures. Nests are made of paper and the outer shell encloses a comb that supports the developing yellow jacket brood. Unlike honey bees, nests contain no honey or pollen.. Although adults feed primarily on items rich in sugars and carbohydrates (fruits, flower nectar, tree sap, apple ...
This is the time of year that Extension agents receive numerous calls about yellow jackets, hornets and how to control them. Many folks dont know the difference between the various types of hornets and yellow jackets we have in Georgia. The confusion is understandable, considering yellow jackets, wasps and hornets are all in the Vespidae family, and they all make their home in the state. Even within the same species individual wasps, hornets and yellow jackets have varying color patterns, depending on whether they are a male, a worker or a queen. To add to the confusion, many people use the terms hornet and yellow jacket interchangeably. For example, the bald-faced hornet is actually a type of yellow jacket.. In general, the term hornet is used for species that nest above ground, and the term yellow jacket is used for those that make nests in the ground. Colonies start each spring when a single queen, who mated the previous fall and then overwintered in the soil or leaf litter - starts a nest. ...
The citrus leafminer (CLM) probably originated in Asia and its host range includes citrus species and a few closely-related Rutaceae (Heppner 1993, Knapp et al. 1995). The citrus leafminer has a relatively simple life history: adult males and females emerge in the early morning hours and mate at dusk and females begin to deposit eggs about 24 hours later on tender new leaves 10-20 mm in length (also called flush) during the night. A single female can deposit approximately 50 eggs during her life. The eggs mature within a day in summer and the young larvae immediately chew their way into the tiny leaf, where each produces a mine. There are three larval stages found within the mine and, after five to six days in summer, the larvae become prepupae, a nonfeeding stage. The prepupa produces silk to form a closed pupal chamber, usually made by folding the edge of the leaf. Molting to the pupal stage occurs within this protected chamber and, after about six days, adults emerge from the end of the ...
The primary, solitary parasitoids Asobara tabida Nees (Braconidae: Alysiinae) and Leptopilina heterotoma (Thomson) (= Pseudeucoila bochei Weld): Eucoilidae) are sympatric, show seasonal overlap and share the same hosts, viz. larvae of Drosophila species. Discrimination between unparasitized hosts and hosts parasitized by the other species was studied. No differences were found in their behaviour towards the two kinds of hosts: these were accepted equally well for parasitization.
Parasitoids were initially recognized from the order Hymenoptera, but later research showed that a number of families in the Diptera order and one in the Coleoptera order also contain true parasitoids. In describing parasitic insects, the term parasitoid was first used in Reuter 1913. His definition referred to an organism that goes through complete metamorphosis and whose larvae are parasitic but whose adults are free living (see Defining Parasitoids). Since that time, the term has been greatly refined to accommodate the plethora of life-history strategies that are found in parasitoids. Some of the most important pioneering research on host-parasitoid interactions was performed by George Salt (Salt 1941) and Stanley Flanders (Flanders 1942 and Flanders 1950), whose early works on development and reproduction are still considered to be of profound importance today. Their studies also influenced later generations of entomologists working on parasitoids. Doutt 1959 wrote the first comprehensive ...

Cryptic Lineages in the Cardiocondyla sl. kagutsuchi Terayama (Hymenoptera: Formicidae) Discovered by Phylogenetic and Morphological Approaches
Animal mitochondrial genomes have provided large and diverse datasets for evolutionary studies. Here, the first two representative mitochondrial genomes from the family Pompilidae (Hymenoptera: Vespoidea) were determined using next-generation sequencing. The sequenced region of these two mitochondrial genomes from the species Auplopus sp. and Agenioideus sp. was 16,746 bp long with an A + T content of 83.12% and 16,596 bp long with an A + T content of 78.64%, respectively. In both species, all of the 37 typical mitochondrial genes were determined. The secondary structure of tRNA genes and rRNA genes were predicted and compared with those of other insects. Atypical trnS1 using abnormal anticodons TCT and lacking D-stem pairings was identified. There were 49 helices belonging to six domains in rrnL and 30 helices belonging to three domains in rrns present. Compared with the ancestral organization, four and two tRNA genes were rearranged in mitochondrial genomes of Auplopus and Agenioideus, respectively.

AU - Cooper, Steven J.B.. AU - Schwarz, Michael P.. PY - 1999/1. Y1 - 1999/1. N2 - An hypothesis of genealogical relationships among taxa provides an historical map along which character evolution (e.g., social traits) can be traced to reveal patterns of common origin or repeated but independent evolution. To investigate the evolution of social traits in the allodapine bee genus Exoneurella, we have derived a species phylogeny based on 32 morphological features of adult and immature stages and sequences from 2 mitochondrial DNA genes, cytochrome oxidase I (COI) and cytochrome b (Cyt b). The morphological and COI data support the close relationship of Brevineura and Exoneurella in accord with previous hypotheses of phylogenetic relationships among allodapine bees. In contrast, the Cyt b data supported the ...

Host choice behavior in insect parasitoids and herbivores has been predicted to vary dynamically in response to external and internal factors acting on a foraging female; physiological state and egg load in particular have been shown to play a major role. In my dissertation, I addressed the role of physiological state in parasitoid host choice behavior at the host species level under field conditions. The parasitoid of choice was the classical biological control agent Binodoxys communis Matsumura that has been released in 2007 throughout the Midwestern USA as part of a classical biological control project against the invasive soybean aphid, Aphis glycines (Gahan). First, I designed a series of laboratory experiments to assess egg load and the risk of egg limitation in female B. communis in response to temperature, sugar feeding, and host availability. These experiments showed that B. communis maintains a constant egg load by varying its egg maturation rate in response to oviposition events. I ...

Description: There is extraordinary diversity in sexual dimorphism (SD) among animals, but little is known about its epigenetic basis. To study the epigenetic architecture of SD in a haplodiploid system, we performed RNA-seq and whole-genome bisulfite sequencing of adult females and males from two closely related parasitoid wasps, Nasonia vitripennis and Nasonia giraulti. More than 75% of expressed genes displayed significantly sex-biased expression. As a consequence, expression profiles are more similar between species within each sex than between sexes within each species. Furthermore, extremely male- and female-biased genes are enriched for totally different functional categories: male-biased genes for key enzymes in sexpheromone synthesis and female-biased genes for genes involved in epigenetic regulation of gene expression. Remarkably, just 70 highly expressed, extremely male-biased genes account for 10% of all transcripts in adult males. Unlike expression profiles, DNA methylomes are ...

Due to the relatively recent invasion of exotic Tephritidae pest species the interests in Tephritidae fruit fly management increased and so also the number of studies on both the exotic and the native fruit flies and their parasitoids. The exotic Bactrocera dorsalis (Diptera: Tephritidae) causes serious damage to fruit trees thereby threatening the horticulture industry. Until now, native parasitoids of B. dorsalis have never been reared most likely owing to encapsulation of their eggs inside the host and as a result for B. dorsalis to become a sink for native parasitoids. Because of the above and the fact that Fopius arisanus (Hymenoptera: Braconidae) was at the time the most successful natural enemy in classical biological control programs of fruit flies in other parts of the world, it was shipped from a laboratory colony at icipe, Nairobi, Kenya in 2008 to IITA-Benin where it was mass-reared in an insectary for experimental releases. Studies on interspecific competition between the exotic ...
Bees, wasps, yellow jackets, and hornets belong to a class of insects called Hymenoptera. Most insect stings cause only minor discomfort. Stings can occur anywhere on the body and can be painful and frightening for a child. Yellow jackets cause the most allergic reactions in the US. Stings from these insects cause three to four times more deaths than poisonous snake bites, due to severe allergic reaction. Fire ants, usually found in southern states, can sting multiple times, and the sites are more likely to become infected.. The two greatest risks from most insect stings are allergic reaction (which can sometimes be fatal if the allergic reaction is severe enough) and infection (more common and less serious).. ...

Many studies have investigated relationships between the volume of whole brains and/or particular brain centres and the behavioural repertoire, cognitive capacities, social life-style or food preference in a wide range of vertebrate and invertebrate species [1-9]. When relating volumes of brain centres to cognitive capacities, it becomes particularly interesting to quantify brain centres involved in learning and memory, such as the insect mushroom bodies (MBs) [10-15]. In Hymenoptera (a large insect order comprising sawflies, wasps, bees and ants), the MBs can be voluminous in relation to other brain regions [16-22] and contain large numbers of intrinsic neurons (Kenyon cells, KCs) [23-25]. Furthermore, in Hymenoptera, the MBs receive multimodal sensory input (in particular mostly olfaction and vision) segregated into different subdivisions of the MBs [26,27]. Olfactory and visual projection neurons form distinct synaptic complexes (microglomeruli, MG) with KC dendrites in the olfactory lip or ...
INTRODUCTION. Lepidoptera pests can cause significant damage to eucalyptus plantations in Brazil (Zanuncio et al. 1993,1998, 2001, Bernardino et al. 2007). Euselasia eucerus (Hewitson, 1872) (Lepidoptera: Riodinidae), also reported as Euselasia apisaon (Dalman, 1823) (Zanuncio et al. 1990, Murta et el. 2008), is a Brazilian native insect and its caterpillars are commonly found in Eucalyptus spp. plantations in São Paulo, Rio Grande do Sul, Santa Catarina and Minas Gerais States, Brazil in outbreaks conditions (Zanuncio et al. 1994). The entire developmental cycle of E. eucerus takes place on Eucalyptus trees, this insect lays its egg clusters on their leaves and its caterpillars are gregarious and pupate on leaves of Eucalyptus spp. (Zanuncio et al. 1990). Euselasia eucerus eggs are parasitized by Trichogramma maxacalii Voegelé and Pointel, 1980, Trichogramma demoraesi Nagaraja, 1983 and Trichogramma acacioi Brun, Moraes and Soares, 1984 (Hymenoptera: Trichogrammatidae); its caterpillars and ...
In order to deposit her eggs inside the tissue of a living plant the female needs relatively much force. Often the terminal segments are adapted to the job, mostly by being heavily chitinised and hardened, like for example in the Agromyzidae, Cecidomyiidae, and Tephritidae. In the sawflies, Tenthredinidae, the ovipositor has taken the shape of a little saw. ...

Today were taking the wraps off of two simple, but handy tools that we have developed to encourage wider adoption of the HAO. The first, our analyzer is simply a tool that takes a block of text and compares it to labels found in the HAO. This tool is aimed at addressing a commonly seen element of taxonomic revisions: the statements in a Materials and Methods section that indicate where anatomic concepts were first defined or in what context they are being used (e.g. wing venation is described following the conventions of Smith, 1945). The analyzer allows users to explicitly reference anatomical concepts by providing resolvable URIs for them. It further highlights where potential conflicts may arise, for example, youre using paramere, did you know that paramere many different ways? (try paramere for fun ...
Accessory nuclei bud off from the membrane of the nucleus, the cellular structure that contains the chromosomes. By the time the egg is fully developed, it contains several hundred accessory nuclei that look much like the nucleus except that they dont contain chromosomes. Late in the development of the egg cell, the accessory nuclei disintegrate and centrosomes appear in the same locations in the cell. Right before the egg is laid, the membranes of the accessory nuclei break down, and at the same time the centrosomes begin to form, Ferree said. One of the most striking aspects of this mechanism is the large number of accessory nuclei and centrosomes that form in the developing eggs of these Hymenopteran insects. You only need two centrosomes, and they make hundreds of them. So they go through a lot of work to make a male, Sullivan said. A lot of energy goes into making these centrosomes, and if the egg gets fertilized they dont use them--the centrosome from the sperm is used ...
Knowledge of the cost of parasitism and the competitive ability of parasitized larvae is important for understanding the evolution of resistance. We used larvae of two Drosophila species as hosts for two parasitoid species which differ in their counter-resistance mechanism. Parasitism by Leptopilina heterotoma leads to a reduction in survival, in contrast to parasitism by Asobara tabida. This can be explained by L. heterotoma having a counter-defence mechanism that actively interferes with the hosts immune system. Parasitized D. melanogaster larvae, which can encapsulate the parasitoids egg to some degree, tend to suffer from a slight reduction in competitive ability, as opposed to parasitized D. subobscura larvae, which are unable to mount an immune response to parasitoids. Combined with earlier work, our results suggest that, in this system, the costs of actual defence are lower than the costs of maintaining an efficient immune system.
doi: 10.1590/S1984-46702011000300012 The Brazilian Cerrado (a savanna like vegetation) once occupied some 2 million square kilometers, representing about 21% of the Brazilian territory (Bridgewater et al. 2004). The Cerrado was recently recognized as one of the world hotspots for biodiversity conservation (Myers et al. 2000) because of its high endemism and rates of biodiversity loss due to recent human occupation and agricultural expansion; however, only 2.2% of its area is under legal protection (Klink & Machado 2005). The relatively high level of landscape conversion to agriculture is a major threat to the conservation of Cerrados biodiversity. It is estimated that around 55% of the biome has been already deforested (Klink & Machado 2005, Silva et al. 2006). Habitat edges are a ubiquitous feature of modern fragmented landscapes and have profound influences on the spatial distribution of many species (Ewers & Didham 2008). Edge effects induce different micro-environmental conditions from ...
