HSP27 multimerization mediated by phosphorylation-sensitive intermolecular interactions at the amino terminus. (1/1413)

Distinct biochemical activities have been reported for small and large molecular complexes of heat shock protein 27 (HSP27), respectively. Using glycerol gradient ultracentrifugation and chemical cross-linking, we show here that Chinese hamster HSP27 is expressed in cells as homotypic multimers ranging from dimers up to 700-kDa oligomers. Treatments with arsenite, which induces phosphorylation on Ser15 and Ser90, provoked a major change in the size distribution of the complexes that shifted from oligomers to dimers. Ser90 phosphorylation was sufficient and necessary for causing this change in structure. Dimer formation was severely inhibited by replacing Ser90 with Ala90 but not by replacing Ser15 with Ala15. Using the yeast two-hybrid system, two domains were identified that were responsible for HSP27 intermolecular interactions. One domain was insensitive to phosphorylation and corresponded to the C-terminal alpha-crystallin domain. The other domain was sensitive to serine 90 phosphorylation and was located in the N-terminal region of the protein. Fusion of this N-terminal domain to firefly luciferase conferred luciferase with the capacity to form multimers that dissociated into monomers upon phosphorylation. A deletion within this domain of residues Arg5-Tyr23, which contains a WDPF motif found in most proteins of the small heat shock protein family, yielded a protein that forms only phosphorylation-insensitive dimers. We propose that HSP27 forms stable dimers through the alpha-crystallin domain. These dimers further multimerize through intermolecular interactions mediated by the phosphorylation-sensitive N-terminal domain.  (+info)

Photorhabdus luminescens W-14 insecticidal activity consists of at least two similar but distinct proteins. Purification and characterization of toxin A and toxin B. (2/1413)

Both the bacterium Photorhabdus luminescens alone and its symbiotic Photorhabdus-nematode complex are known to be highly pathogenic to insects. The nature of the insecticidal activity of Photorhabdus bacteria was investigated for its potential application as an insect control agent. It was found that in the fermentation broth of P. luminescens strain W-14, at least two proteins, toxin A and toxin B, independently contributed to the oral insecticidal activity against Southern corn rootworm. Purified toxin A and toxin B exhibited single bands on native polyacrylamide gel electrophoresis and two peptides of 208 and 63 kDa on SDS-polyacrylamide gel electrophoresis. The native molecular weight of both the toxin A and toxin B was determined to be approximately 860 kDa, suggesting that they are tetrameric. NH2-terminal amino acid sequencing and Western analysis using monospecific antibodies to each toxin demonstrated that the two toxins were distinct but homologous. The oral potency (LD50) of toxin A and toxin B against Southern corn rootworm larvae was determined to be similar to that observed with highly potent Bt toxins against lepidopteran pests. In addition, it was found that the two peptides present in toxin B could be processed in vitro from a 281-kDa protoxin by endogenous P. luminescens proteases. Proteolytic processing was shown to enhance insecticidal activity.  (+info)

In vivo regulation of beta-MHC gene in rodent heart: role of T3 and evidence for an upstream enhancer. (3/1413)

Cardiac beta-myosin heavy chain (beta-MHC) gene expression is mainly regulated through transcriptional processes. Although these results are based primarily on in vitro cell culture models, relatively little information is available concerning the interaction of key regulatory factors thought to modulate MHC expression in the intact rodent heart. Using a direct gene transfer approach, we studied the in vivo transcriptional activity of different-length beta-MHC promoter fragments in normal control and in altered thyroid states. The test beta-MHC promoter was fused to a firefly luciferase reporter gene, whereas the control alpha-MHC promoter was fused to the Renilla luciferase reporter gene and was used to account for variations in transfection efficiency. Absolute reporter gene activities showed that beta- and alpha-MHC genes were individually and reciprocally regulated by thyroid hormone. The beta-to-alpha ratios of reporter gene expression demonstrated an almost threefold larger beta-MHC gene expression in the longest than in the shorter promoter fragments in normal control animals, implying the existence of an upstream enhancer. A mutation in the putative thyroid response element of the -408-bp beta-MHC promoter construct caused transcriptional activity to drop to null. When studied in the -3, 500-bp beta-MHC promoter, construct activity was reduced ( approximately 100-fold) while thyroid hormone responsiveness was retained. These findings suggest that, even though the bulk of the thyroid hormone responsiveness of the gene is contained within the first 215 bp of the beta-MHC promoter sequence, the exact mechanism of triiodothyronine (T3) action remains to be elucidated.  (+info)

Glucose generates sub-plasma membrane ATP microdomains in single islet beta-cells. Potential role for strategically located mitochondria. (4/1413)

Increases in the concentration of free ATP within the islet beta-cell may couple elevations in blood glucose to insulin release by closing ATP-sensitive K+ (KATP) channels and activating Ca2+ influx. Here, we use recombinant targeted luciferases and photon counting imaging to monitor changes in free [ATP] in subdomains of single living MIN6 and primary beta-cells. Resting [ATP] in the cytosol ([ATP]c), in the mitochondrial matrix ([ATP]m), and beneath the plasma membrane ([ATP]pm) were similar ( approximately 1 mM). Elevations in extracellular glucose concentration (3-30 mM) increased free [ATP] in each domain with distinct kinetics. Thus, sustained increases in [ATP]m and [ATP]pm were observed, but only a transient increase in [ATP]c. However, detectable increases in [ATP]c and [ATP]pm, but not [ATP]m, required extracellular Ca2+. Enhancement of glucose-induced Ca2+ influx with high [K+] had little effect on the apparent [ATP]c and [ATP]m increases but augmented the [ATP]pm increase. Underlying these changes, glucose increased the mitochondrial proton motive force, an effect mimicked by high [K+]. These data support a model in which glucose increases [ATP]m both through enhanced substrate supply and by progressive Ca2+-dependent activation of mitochondrial enzymes. This may then lead to a privileged elevation of [ATP]pm, which may be essential for the sustained closure of KATP channels. Luciferase imaging would appear to be a useful new tool for dynamic in vivo imaging of free ATP concentration.  (+info)

Molecular systematics of cytochrome oxidase I and 16S from Neochlamisus leaf beetles and the importance of sampling. (5/1413)

If a gene tree is to be judiciously used for inferring the histories of closely related taxa, (1) its topology must be sufficiently resolved and robust that noteworthy phylogenetic patterns can be confidently documented, and (2) sampling of species, populations, and pertinent biological variation must be sufficiently broad that otherwise misleading sources of genetic variation can be detected. These principles are illustrated by the complex gene tree of Neochlamisus leaf beetles that I reconstructed using 90,000 bp of cytochrome oxidase I (COI) and 16S mitochondrial DNA (mtDNA) sequences from over 100 specimens. Cytochrome oxidase I haplotypes varied up to 25.1% within Neochlamisus and up to 11.1% within the gibbosus species group, while exhibiting very low A + T bias for insect mtDNA (63%), low transition saturation, and conservative patterns of amino acid variation. 16S exhibited lower sequence divergences and greater A + T bias and transition saturation than COI, and substitutions were more constrained in stems than in loops. Comparisons with an earlier study of Ophraella leaf beetles highlighted conservative and labile elements of molecular evolution across genes and taxa. Cytochrome oxidase I parsimony and neighbor-joining analyses strongly supported a robust mtDNA genealogy that revealed the monophyly of Neochlamisus and of the gibbosus species group. Phylogeographic relationships suggested that the eastern U.S. gibbosus group derives from southwestern velutinus group ancestors. Haplotypes from individual velutinus group species clustered monophyletically, as expected. However, haplotypes from each of several gibbosus group taxa were polyphyletically distributed, appearing in divergent parts of the tree. 16S provided a less-resolved gibbosus group topology that was congruent with the COI tree and corroborated patterns of mitochondrial polyphyly. By subsampling haplotypes corresponding to particular species, populations, and ecological variants of gibbosus group taxa, I demonstrate that recovered topologies and genetic distances vary egregiously according to sampling regime. This study thus documents the potentially dire consequences of inadequate sampling when inferring the evolutionary history of closely related and mitochondrially polyphyletic taxa.  (+info)

A visual evoked potential correlate of global figure-ground segmentation. (6/1413)

Human observers discriminated the global orientation of a texture-defined figure which segregated from a texture surround. Global figure discriminability was manipulated through within-figure collinearity, figure-surround interaction, and figure connectedness, while the local orientation contrast at edges between figure and surround was kept constant throughout all the experiments. Visual evoked potentials (VEPs) were recorded during onset-offset stimulation in which the figure cyclically appeared and disappeared from a uniform texture background. A difference component was obtained by subtraction of offset-from onset-VEP. Two negative peaks of the difference component are found with latencies around 140-160 and 200-260 ms, respectively. Enhanced discriminability of the global figure reduced (11-25 ms) the latency of the second peak, hence indicating that the 200-260 ms component was produced by global figure-ground segmentation.  (+info)

Seeing better at night: life style, eye design and the optimum strategy of spatial and temporal summation. (7/1413)

Animals which need to see well at night generally have eyes with wide pupils. This optical strategy to improve photon capture may be improved neurally by summing the outputs of neighbouring visual channels (spatial summation) or by increasing the length of time a sample of photons is counted by the eye (temporal summation). These summation strategies only come at the cost of spatial and temporal resolution. A simple analytical model is developed to investigate whether the improved photon catch afforded by summation really improves vision in dim light, or whether the losses in resolution actually make vision worse. The model, developed for both vertebrate camera eyes and arthropod compound eyes, calculates the finest spatial detail perceivable by a given eye design at a specified light intensity and image velocity. Visual performance is calculated for the apposition compound eye of the locust, the superposition compound eye of the dung beetle and the camera eye of the nocturnal toad. The results reveal that spatial and temporal summation is extremely beneficial to vision in dim light, especially in small eyes (e.g. compound eyes), which have a restricted ability to collect photons optically. The model predicts that using optimum spatiotemporal summation the locust can extend its vision to light intensities more than 100,000 times dimmer than if it relied on its optics alone. The relative amounts of spatial and temporal summation predicted to be optimal in dim light depend on the image velocity. Animals which are sedentary and rely on seeing small, slow images (such as the toad) are predicted to rely more on temporal summation and less on spatial summation. The opposite strategy is predicted for animals which need to see large, fast images. The predictions of the model agree very well with the known visual behaviours of nocturnal animals.  (+info)

Sequencing and characterization of the citrus weevil, Diaprepes abbreviatus, trypsin cDNA. Effect of Aedes trypsin modulating oostatic factor on trypsin biosynthesis. (8/1413)

Trypsin mRNA from the citrus weevil, Diaprepes abbreviatus, was reverse transcribed and amplified by PCR. A cDNA species of 513 bp was cloned and sequenced. The 3' and 5' ends of the gene (262 bp and 237 bp, respectively) were amplified by rapid amplification of cDNA ends, cloned and sequenced. The deduced sequence of the trypsin cDNA (860 bp) encodes for 250 amino acids including 11 amino acids of activation and signal peptides and exhibited 16.8% identity to trypsin genes of selected Lepidoptera and Diptera. A three-dimensional model of Diaprepes trypsin contained two domains of beta-barrel sheets as has been found in Drosophila and Neobellieria. The catalytic active site is composed of the canonical triad of His41, Asp92 and Ser185 and a specificity pocket occupied by Asp179 with maximal activity at pH 10.4. Southern blot analysis indicated that at least two copies of the gene are encoded by Diaprepes midgut. Northern blot analysis detected a single RNA band below 1.35 kb at different larval ages (28-100 days old). The message increased with age and was most abundant at 100 days. Trypsin activity, on the other hand, reached a peak at 50 days and fell rapidly afterwards indicating that the trypsin message is probably regulated translationally. Feeding of soybean trypsin inhibitor and Aedes aegypti trypsin modulating oostatic factor affected trypsin activity and trypsin biosynthesis, respectively. These results indicate that Diaprepes regulates trypsin biosynthesis with a trypsin modulating oostatic factor-like signal.  (+info)

Unfortunately, the information is lacking regarding differentially expressed miRNAs following imidacloprid treatment in L. decemlineata. In this study, next-generation sequencing and quantitative real-time polymerase chain reaction (qRT-PCR) were used to identify modulated miRNAs in imidacloprid-treated versus untreated L. decemlineata. This approach identified 33 differentially expressed miRNAs between the two experimental conditions. Of interest, miR-282 and miR-989, miRNAs previously shown to be modulated by imidacloprid in other insects, and miR-100,
The closest permanent populations of Colorado potato beetles are found in Russia, north and south of Lake Ladoga. Occasional overwintered beetles can be found in Finland, mainly in the vicinity of the eastern border. The Colorado potato beetles that burrowed into the ground as adults come out of hibernation when the temperature of the soil exceeds 15 degrees. This usually happens at the end of June and beginning of July.. It is difficult to find single beetles, but there can be findings of several dozen adult beetles in a colony that has overwintered. The adult beetles and larvae first eat holes in the potato leaves, and later they eat the leaves completely. In this case the area has to be examined carefully for findings of adult Colorado potato beetles or egg masses. The Colorado potato beetles only eat potatoes or other solanaceae. In the home garden there are many other common insects eating the leaves of plants.. An adult Colorado potato beetle is about one centimetre long. There are 10 ...
Winter mortality is a major factor regulating population size of the mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae). Glycerol is the major cryoprotectant in this freeze intolerant insect. We report findings from a gene expression study on an overwintering mountain pine beetle population over the course of 35 weeks. mRNA transcript levels suggest glycerol production in the mountain pine beetle occurs through glycogenolytic, gluconeogenic and potentially glyceroneogenic pathways, but not from metabolism of lipids. A two-week lag period between fall glycogen phosphorylase transcript and phosphoenolpyruvate carboxykinase transcript up-regulation suggests that gluconeogenesis serves as a secondary glycerol-production process, subsequent to exhaustion of the primary glycogenolytic source. These results provide a first look at the details of seasonal gene expression related to the production of glycerol in the mountain pine beetle.
The invention provides transgenic plants and transformed host cells which express modified cry 3B genes with enhanced toxicity to Coleopteran insects. Also disclosed are methods of making and using these transgenic plants, methods of making recombinant host cells expressing these δ-endotoxins, and methods of killing insects such as Colorado potato beetle (Leptinotarsa decemlineata), southern corn rootworm (Diabrotica undecimpunctata howardi Barber) and western corn rootworm (Diabrotica virgifera virgifera LeConte.
Colorado potato beetle. Coloured scanning electron micrograph (SEM) of the larva of a Colorado potato beetle (Leptinotarsa decemlineata). This agricultural pest hatches from an egg laid on the underside of a potato leaf, and begins to feed. Once fully grown after 2-3 weeks, it burrows into the soil and transforms into a pupa which survives the winter. The adult beetle emerges in the spring to feed on newly sprouted potato plants before female beetles lay more eggs. Magnification unknown. - Stock Image Z330/0280
Bean leaf beetle injury to soybean seedlings (two plants). Where do bean leaf beetles spend the winter? Bean leaf beetle adults overwinter throughout the Midwest primarily beneath leaf litter in woodlots surrounding soybean fields. Dr. Larry Pedigo, professor of entomology, Iowa State University, reports that approximately 80% of adults spend the winter in wooded areas, 20% beneath soybean residue in fields, and fewer than 1% in protected areas of alfalfa stands, cornfields, and other grassy areas. Bean leaf beetle adults become active in April and are commonly observed in stands of alfalfa. While in alfalfa, some feeding and egg laying takes place; however, bean leaf beetles are not considered to be of any economic importance to this crop. When do bean leaf beetle adults abandon alfalfa? As the first cutting of alfalfa is taking place and the earliest-planted soybean fields begin to emerge, bean leaf beetle adults leave alfalfa and colonize soybeans. Females that fly to soybean fields have ...
TY - JOUR. T1 - Penetration of Steinernematid nematodes (Nematoda. T2 - Steinernematidae) into Japanese beetle larvae, Popillia japonica (Coleoptera: Scarabaeidae). AU - Cui, Liwang. AU - Gaugler, Randy. AU - Wang, Yi. PY - 1993/1/1. Y1 - 1993/1/1. N2 - Penetration of infective juveniles of Steinernema glaseri and Steinernema carpocapsae into Japanese beetle larvae, Popillia japonica, was compared using external exposure and injection methods. Steinernematids entered the grubs through the mouth and anus, but not through the spiracles or cuticle. For all treatments, S. glaseri had higher levels of penetration than S. carpocapsae. Penetration of the gut by orally injected nematodes began 4-6 hr postinoculation. All regions of the gut were penetrated, with more than 82% of all penetrating nematodes invading the host hemocoel via the midgut. Gastric cecae were important sites for nematode penetration. Penetration sites of anally injected nematodes were the rectal sac of the hindgut. Penetration ...

This is Cicindela scutellaris (festive tiger beetle), one of the six species of tiger beetles that we found last September at Monroe Canyon in the Pine Ridge area of northwestern Nebraska. The red elytra and green head and pronotum are characteristic of nominotypical populations of this species that are found in sandy habitats throughout the Great Plains. This is your classic tiger beetle in a classic tiger beetle pose; however, photographs such as this are not so easy to come by. The biggest challenge is the beetle itself - rarely are they so accommodating to allow this nice lateral profile perspective with the head slightly cocked towards the camera while standing up on their front legs. This posture is seen only when the beetles are warm and active, and warm beetles are skittish beetles that yield lots of not-as-interesting back shots (head directed away from the camera) as they persistently run away from the photographer. Cooler temperatures make them less skittish and easier to approach ...
Wherever we find many species of tiger beetles living together, we also find many birds, butterflies, dragonflies, and other species. In this way, tiger beetles can help us understand which areas of land are most important to save or protect.. In many parts of the world the species that are there have not been studied or dont even have official names yet. For example, it takes years to know how many bird species are in an area. Tiger beetles, however, are very obvious and easy to identify wherever they are. Because of this they have been studied so much around the world that even in the middle of the Amazonian forest we can quickly count how many species of tiger beetles are there.. If we want an actual estimate of the number of species of birds, butterflies, and other animals that are in an area, tiger beetles can help us yet again. Knowing the number of tiger beetle species in an area can help us estimate species numbers for other animals. This saves us the time and money it would take to ...
Sunburst Diving Beetles are black with bright yellow spots. The spots warn predators that they can protect themselves by releasing a chemical that tastes bad. Sunburst Diving Beetles are also called Spotted Diving Beetles. They are small beetles. Adults grow to approximately 1/2 of an inch in length. They have a pair of thin antennae and three pairs of legs. Their back legs have a thick fringe of hairs to enable strong swimming. The females are slightly larger than the males. The males also have suction disks on each foreleg.. Sunburst Diving Beetles breathe oxygen but they spend much of their time underwater. Adults are able to do this by creating a bubble of air that they take underwater. While floating on the water the Sunburst Diving Beetle will tip its abdomen up in the air and gather the air under their wing covers to use them like the air tanks human scuba divers use. They can stay submerged for several minutes. Larvae have a siphon like a snorkel coming out of the end of their bodies ...
The Salt Creek tiger beetle, Cicindela nevadica lincolniana, is a critically endangered subspecies of tiger beetle endemic to the saline wetlands of northern Lancaster County, Nebraska, adjacent to and immediately to the north of the city of Lincoln. It is a predatory insect, using its mandibles to catch other insects. The beetle is one of the rarest insects in North America; surveys showed that 194 adults existed in 2009, down from 263 in 2008, and 777 in 2000. However, efforts are continuing to boost the population, which in 2013 numbered 365 beetles: one beetle for each day in a regular year. The Salt Creek tiger beetle measures about 12 mm (0.5 in.) in length. The beetle has a metallic brown to dark olive green coloration, with a dark metallic green underside. Its body form and color pattern differs from other tiger beetle subspecies. Little is known about the life cycle of the Salt Creek tiger beetle. Adults emerge around June 1 and disappear five or six weeks later; populations peak about ...
It is still likely that new Colorado beetle infestations will be found. The longer the warm weather continues, the faster the multiplication and spread of the beetle will be. In addition, the Colorado beetles will spread into new areas with the air flows from any possible thunderstorm fronts.. Eviras monitoring teams are continuing the surveys in the areas of Southeast Finland and North Karelia for the time being. Any potential sightings or suspected infestations of Colorado beetles are to be reported to Eviras plant protection service or to the TE-centres plant protection inspector. The general emergency phone number for reporting the findings is 0400 442 209..

latidens, Ips pini, Pseudips mexicanus) were also detected in small numbers at several sites. Other potentially damaging bark beetles, also collected in small numbers, included Dendroctonus species such as the red turpentine beetle (D. valens), western pine beetle (D. brevicomis), and even mountain pine beetle (D. ponderosae). Although samples are still being processed, the remainder of beetles collected appear to be secondary bark beetles, which typically only infest already dead or dying trees. All bark beetles examined thus far are native to Oregon, and such a wide diversity is not unexpected. However, the historical distribution of beetles such as the pine engraver (Ips pini), as well as the western and mountain pine beetle, does not typically include the Valley. These beetles are adapted to the warmer, drier climates of eastern and southwest Oregon. The small number detected in the survey suggests that they likely originated from some type of wood product being moved to/through the Valley, ...

Insecticides- A number of insecticides are available to kill Japanese beetles. by spraying the affected plants with Japanese beetle killer withn ingredients such as carbaryl or pyrethrin). Pyrethrin-based insecticide is a safe and effective way to control these pests on vegetables, grapes, raspberries, flowers, roses, trees and shrubs. In addition to controlling Japanese beetles, it also controls cucumber beetles, flea beetles, cabbageworms, and more. As soon as you notice beetles, begin spraying. The beetles release chemicals called pheromones into the air. These pheromones attract other beetles. So if you see a few of the bugs, theyll probably attract more. Get rid of Japanese beetles early, before they can invite more of their friends to feed on your plants. ...
RESISTANCE ASSAY METHODS. In the field, insecticide resistance can be observed as little or no reduction in the density of beetle populations and their damage to potato plants following insecticide application (assuming that other possible reasons, such as poor timing or malfunctioning spray equipment, could be ruled out). In the laboratory, resistance can be measured as an increase in the dose (LD50) or concentration (LC50) of the toxin required to kill 50% of the exposed population. LD50 values are used when the exact dose received by each tested insect is known (e.g., when a droplet of the known volume of the known concentration of insecticide solution is applied topically to an insect). LC50 values are used when the exact dose is not known (e.g., when an insect feeds on the leaf treated with the known concentration of insecticide solution, but the exact amount of ingested material is not measured). Bioassays normally consist of preparing serial dilutions of tested chemicals and then applying ...
Many livestock producers are unaware that herd management practices influence the effectiveness of dung beetles. Dung beetles are important to healthy cattle pasture ecosystems as they provide for nutrient recycling, removal of waste products from the soil surface and assist in the reduction of pestiferous flies.. Numerous exotic dung beetles have been accidentally or intentionally introduced to the North American continent and several of these have become established.. In "Indigenous and Exotic Dung Beetles (Coleoptera: Scarabaeidae and Geotrupidae) Collected in Florida Cattle Pastures," which will appear in the next issue of Annals of the Entomological Society of America, entomologists from the University of Florida surveyed for the presence and distribution of dung beetles on four cattle farms in north central Florida over a 3.5-yr period, and they identified 39 species from 20 genera, with a total of 62,320 beetles collected in traps.. Although most were natives, six exotic species were ...
Beetles make up the largest category of insects in the world, accounting for approximately 25% of all life forms on earth. In fact, there are more than 5 million different species of beetles.. Beetles are easily identified by their hard outer shell, which covers their wings. Their wings are exposed only during flight. A beetles body consists of three sections: a head, a thorax, and an abdomen.. Several types of beetles feed on wood. This can cause a lot of damage to wood structures primarily because while the wood is being eaten, the beetles remain unseen. This is true of Powder Post Beetles, Old House Borer Beetles, Bark Beetles, Citrus Long-Horned Beetles, Asian beetles, and other species. Powder Post Beetles, among others, grow from eggs that are laid in the wood. Another species of beetle, the Citrus Long-Horned Beetle, was introduced into the United States as recently as 1999, and is currently without any natural enemies. Although not known as yet, the damage they will create is expected ...

Asian Longhorned Beetles currently affect New York, Brooklyn, Long Island and Chicago. Many of the species of trees in the northeastern United States are susceptible to attack by these beetles. Scientists and entomologists have developed different avenues to dissuade further attacks and infestation of the Asian Longhorned Beetle.. One complication in treating these infestations is due to the beetles dormant periods. For a pesticide to work, it will need to be sprayed repeatedly over an infested area in order to be effective across the beetles different life stages. One such pesticide allegedly killed bees in portions of Europe and is no longer used. Natural methods, such as the introduction of a species of beetle that preys on the Asian Longhorned Beetle, are currently under research and development. Another avenue under research is identification of chemical pheromones that attract male Asian longhorned beetles to females in order to develop traps.. ...

In hairy wet attachment systems, the role of the secretion still remains unclear. It has already been shown that the presence of the fluid is required for generating adhesion in insect adhesive pads. For example, as shown in 1970, attachment was impaired when hairy pads of the bug Rhodnius prolixus were treated with organic solvents (Edwards & Tarkanian 1970). In 1980, experiments with beetles on various substrates also strongly suggested that cohesive forces, surface tension and molecular adhesion, mediated by pad secretion, may be involved in the mechanism of attachment (Stork 1980). It was inferred from experiments (Wallentin et al. 1999; Gorb 2001) that the secretion induces a viscous resistance to detachment of the pad from the substrate and a capillary attraction that applies both before and during detachment (static and dynamic processes). Later, on the scale of individual seta terminal plates, experiments conducted on the fly Calliphora vicina using multiple local force-volume atomic ...

Recurring species interactions can cause species to adapt to each other. Specialization will increase the fitness of symbionts in the coevolved association but may reduce the flexibility of symbiont choice as it will often decrease fitness in interactions with other than the main symbiont species. We analyzed the fitness interactions between a complex of two cryptic mite species and their sympatric burying beetle hosts in a European population. Poecilochirus mites (Mesostigmata, Parasitidae) are phoretic on burying beetles and reproduce alongside beetles, while these care for their offspring at vertebrate carcasses. While Poecilochirus carabi is typically found on Nicrophorus vespilloides beetles, P. necrophori is associated with N. vespillo. It has long been known that the mites discriminate between the two beetle species, but the fitness consequences of this choice remained unknown. We experimentally associated both mite species with both beetle species and found that mite fitness suffered ...
It is noted that insect insulin/insulin-like growth factor/target of rapamycin signaling is critical for the regulation of metamorphosis in holometabolous insects. However, the molecular mechanism remains undetermined. Our previous findings reveal that RNA interference (RNAi)-mediated knockdown of an insulin gene (LdILP2) in Leptinotarsa decemlineata disturbs both 20-hydroxyecdysone (20E) and juvenile hormone (JH) signaling, and impairs pupation. In the present paper, we further observed that the expression of the insulin receptor substrate gene chico (Ldchico) and the phosphoinositide-3-kinase gene pi3k (Ldpi3k92E) was repressed in LdILP2 depleted larvae. Moreover, RNAi of Ldchico or Ldpi3k92E decreased food consumption, affected absorption and metabolism of amino acids and sugars, and reduced expression of several 20E (LdEcR, LdHR3 and LdE75) and JH (LdJHAMT, LdKr-h1 and LdHairy) signaling genes. As a result, larval development was postponed and larval growth was inhibited. Intriguingly, ...
Rove beetles (Atheta coriaria) are generalist predators that feed upon shoreflies, as well as fungus gnats, and thrips.. Adults are slender, dark brown to black hairy beetles, about 1/8 of an inch long, with very short wing covers. Because the adults can fly, this helps them disperse in the greenhouse. Larvae (seen here) are cream colored to brown depending upon their age. Both stages are primarily found in the growing media, hiding in cracks and crevices. Once established in a greenhouse, they will be there year round, but population levels vary depending upon prey populations.. The life cycle of rove beetles from egg to adult is about three weeks at 77° F. Adult females lay approximately 8 eggs per day for the first two weeks after they mature. Eggs hatch in 3 to 4 days into creamy white larvae. (There are three larval stages after which they pupate.). Rove beetles were first introduced as a biological control agent in 2002. More research and grower experience is needed to determine their ...
Chafers were not the only scarabs I encountered in abundance at Borakalalo [National Park], and Ill give you one guess as to what other scarab group I encountered in abundance at this mammal game reserve. Thats right, dung beetles. Never before have I seen such an abundance and diversity of dung beetles in one spot, but then again, never before have I seen such an abundance of dung! The ground was littered with the stuff - antelope such as gemsbok and impala, warthogs, giraffes, and a host of other mammals thrive in the protected confines of the park, and the seasonally dry climate allows their dung to dry quickly and accumulate rather than breaking down and disappearing. It did, however, take a few days before I became aware of the areas dung beetle diversity. Prior to our arrival in the park, the weather had been dry for some time, and so it remained for the first few days we were there. I collected a smattering of different dung beetles during that time, but it seemed like they should be ...
This amazing, gem-like creature, once thought to be extinct, was only recently rediscovered," said Jaclyn Lopez, Florida director and staff attorney at the Center for Biological Diversity. "Now the only place on Earth its known to occupy is threatened with a shopping mall featuring a Walmart and yet another Florida theme park." Miami tiger beetles were presumed extinct until recent surveys detected individuals at three sites in the Richmond pine rocklands in Miami-Dade County. One of the rarest habitats in the United States, pine rocklands are characterized by limestone outcroppings and canopies of Florida slash pine. Unchecked urban and agricultural development has destroyed all but 2 percent of these rare and beautiful habitats.. The Miami tiger beetle has a shiny-green shell that sometimes appears copper colored. Tiger beetles are so named for their aggressive predatory behavior, strong mandibles and fast running speed. Several other endangered species are found in the beetles habitat, ...

The Western corn rootworm only has one generation per year. From July to September females lay up to 500 eggs into the soil where they overwinter. Larvae appear in the following year from the beginning of June on and begin to feed on corn roots at once. Whereas the first instar feeds on external fine foot hairs the second and third instar also burrows into roots. The roots ability to transport water and nutrients, as well as the stability of the maize plant are significantly affected. Also the roots are likely to get secondary fungal infections (root rot). Furthermore the plant tries to compensate the continuing loss of root mass by growing new ones, which drains a lot of energy. This in turn goes at the expense of developing aerial parts relevant for yield. If the weather is humid during this time, yield loss due to larval feeding stays under 30 percent in most cases. In years with dry weather during early summer, as last year in south-eastern Europe and at severe infestation, yield losses up ...

Insects in the family Elateridae are commonly called click beetles (or "typical click beetles" to distinguish them from the related families Cerophytidae, Eucnemidae, and Plastoceridae). Other names include elaters, snapping beetles, spring beetles or skipjacks. This family was defined by William Elford Leach (1790-1836) in 1815. They are a cosmopolitan beetle family characterized by the unusual click mechanism they possess. There are a few closely related families in which a few members have the same mechanism, but all elaterids can click. A spine on the prosternum can be snapped into a corresponding notch on the mesosternum, producing a violent "click" that can bounce the beetle into the air. Clicking is mainly used to avoid predation, although it is also useful when the beetle is on its back and needs to right itself. There are about 9300 known species worldwide, and 965 valid species in North America. Click beetles can be large and colorful, but most are under 2 centimeters long and dull in ...
They defend themselves with noxious secretions. This is typical for the ancient beetle suborder Adephaga to which they belong. They have paired glands in the lower back of the abdomen. These are well developed, and produce noxious or even caustic secretions used to deter would-be predators.. In bombardier beetles these secretions are mixed with volatile compounds and ejected by a small combustion with a loud popping sound and a cloud of hot and acrid gas. This can injure small mammals, such as shrews, and may kill invertebrate predators outright. To humans, getting "bombed" by a bombardier beetle is a decidedly unpleasant experience. This ability has evolved twice - in the flanged bombardier beetles (Paussinae) which are among the most ancient ground beetles, as well as in the typical bombardier beetles (Brachininae) which are part of a more "modern" lineage.. The Anthiini can squirt their defensive secretions for considerable distances and are able to aim with a startling degree of accuracy; in ...
Now a team of scientists has shown that large numbers of modern-day beetle lineages evolved very soon after the first beetles originated, and have persisted ever since. Many modern-day lineages first appeared during the Jurassic period, when the major groups of dinosaurs appeared too.. Lead scientist on the study, Professor Alfried Vogler from Imperial College Londons Department of Life Sciences and the Natural History Museums Department of Entomology, explains: "The large number of beetle species existing today could very well be a direct result of this early evolution and the fact that there has been a very high rate of survival and continuous diversification of many lineages since then." The team behind todays new study - the most extensive of its kind to date - used DNA sequencing and fossil records to compile a comprehensive evolutionary family tree for beetles. By comparing DNA sequences from 1,880 beetle species, the scientists were able to group beetle species that are descended ...

We illustrate more than 300 species of the Geadephagous Coleoptera that occur in Canada. This represents about one third of the Canadian fauna. We have at least one illustration of all known Canadian genera. The Geadepahaga, or terrestrial Adephagan beetles, comprises three families: Carabidae, Trachypachidae, and Rhysodidae. The Carabidae, or ground beetles, is the largest family by far with about 930 species. We have included the tiger beetles in the Carabidae, which have often been placed in a separate family. The Trachypachidae and the Rhysodidae consist of two species each in Canada. Feeding habits and life cycle types are rather diverse. Larvae of a few species are external parasitoids on pupae of other beetles, but adults and larvae of most species are predatory and feed on a wide variety of insects. We have classified the Canadian species into tribes and genera. Subfamilies are not used here because this level of classification is not as stable. We provide illustrated regional lists for ...

Differential interference contrast (DIC) micrograph of a beetle larva living on the mouthparts of a spider-hunting wasp. The beetle is a 1st instar larva of either a rhipiphorid (an unusual family of beetles), or possibly a twisted-wing fly (Strepsiptera). Both Rhipiphorids and Strepsiptera are partially parasitoids of bees or wasps, though they are also known to attack other hosts. The tiny 1st instar larvae are known as triungulins, and board adult bees or wasps (Hymenoptera), in order to be brought back to their nests. Once there, the triungulin attacks either the larvae of the bee or wasp as a parasitoid, or the host of the wasp. Length of beetle larva is 0.1 mm.
Increased mortality of forest trees, driven directly or indirectly by climate change, is occurring around the world. In western North America, whitebark pine, a high elevation keystone species, and lodgepole pine, a widespread ecologically and economically important tree, have experienced extensive mortality in recent climate-driven outbreaks of the mountain pine beetle. However, even in stands experiencing high levels of mortality, some mature trees have survived. We hypothesized that the outbreak acted as a natural selection event, removing trees most susceptible to the beetle and least adapted to warmer drier conditions. If this was the case, genetic change would be expected at loci underlying beetle resistance. Given we did not know the basis for resistance, we used inter-simple sequence repeats to compare the genetic profiles of two sets of trees, survivors (mature, living trees) and general population (trees just under the diameter preferred by the beetles and expected to approximate the genetic
APHIS maintains the Japanese Beetle Quarantine and Regulations that can be found in 7 CFR 301.48. The objective of the Japanese Beetle Quarantine is to protect the agriculture of the Western United States and prevent the human-assisted spread of the beetle from the Eastern U.S. The federal quarantine is designed to reduce artificial spread of Japanese beetles by aircraft. The Western states protected by the Japanese Beetle Quarantine are: Arizona, California, Colorado, Idaho, Montana, Nevada, Oregon, Utah, and Washington.. Pest Identification. ...

Frederick County Master Gardener Program. Japanese beetles, which become active in late June and stick around through August, are a major pest of both agricultural and landscape plants, as anyone who grows roses or grapes in this area can attest. One reason the beetles are so successful at turning healthy plants into disaster areas is that they are an introduced species with no natural enemies in this country. (New Jersey has the dubious distinction of being the first place in the US where Japanese beetles were discovered.) Some 80 years after their initial introduction, they have spread until they cause nearly a half-billion dollars of damage each year. Organic gardeners have basically three types of controls at their disposal: biological controls, traps, and hand-picking.. Most people think of milky spore when they think of biological controls for Japanese beetles. Milky spore is a bacterium that infects the beetles when they are living underground as grubs. Milky spore will work under the ...

Bark beetle infestation remains an issue in the Tahoe Basin. The best prevention availble for Bark beetle is to have a clean and healthy stand of trees. Overcrowding causes stress that weaken your trees and makes them susceptible to beetle attack. Broken limbs, piles of slash, and uncovered firewood can provide habitat for bark beetles. Insecticide can be beneficial in prevention of a beetle attack but will not help a tree that has already been infested. The method of tree mortality caused by bark beetle can be deceptive. The beetles may girdle the tree while feeding on the inner bark or introduce a fungus that clogs the trees water conducting abilities. Either action, or a combination of both, will kill the tree. The tree may retain green needles for two years after infestation and then suddenly turn red, seemingly overnight. The beetles have normally left the tree by this time, on their way to infest other trees. Trees that are showing signs of bark beetle infestation (click here for a more ...
To investigate this further, the researchers repeated the experiments under slightly different conditions. They moved the arena to a planetarium where they were able to control which stars the dung beetles were able to see. Once again, some of the beetles wore caps. This time, they showed the beetles the brightest stars, showed only the Milky Way, and then showed the entire sky. What they found was that the beetles were slow to cross the arena when the brightest stars were visible, but they crossed at normal speed when only the Milky Way was visible and when the entire sky was visible. The beetles with caps had difficulty crossing no matter what.. The researchers concluded that the beetles must be using the Milky Way in order to navigate. This falls in line with the findings of a similar experiment that used a different type of dung beetle, the Scarabaeus zambesianus, which was unable to move in a straight line when the Milky Way wasnt visible.. Of course, in the Northern Hemisphere, the Milky ...
It has been said by many that the native Southern Pine beetle, Dendroctonus frontalis, is one of the most destructive insect pests to pines. Here at Chincoteague National Wildlife Refuge, Loblolly Pine trees are a haven to the Southern Pine beetle for shelter, breeding, nesting, and feeding. These beetles chew and burrow their way through the bark and the inner parts of the tree, killing a healthy tree in a month. Many of the pine trees on Chincoteague National Wildlife Refuge are the perfect habitat for the Southern Pine beetle. Sadly, the tree that allows the beetle to survive will quickly die. A large number of the Loblolly Pine trees, found on Assateague Island are reaching the end of their lifespan and are also affected by salt stress due to sea level rise. Since the trees are already weakening, they make a good starting habitat for the Southern Pine beetle because it is easier to break the trees defenses ...

Managing infestations of certain pests through crop rotation (e.g., planting corn, Zea mays L., and a nonhost crop such as soybean, Glycine max L., in alternative years) has historically been an effective approach; however, the effectiveness of crop rotation for managing many pests (e.g., western corn rootworm, Diabrotica virgifera virgifera LeConte) has begun to fail in many areas of the United States. Recent experimental investigations and model development efforts have shed some light on the population dynamics and behavior of the rotation-resistant phenotype. In addition, there has been growing interest in understanding and modeling pest resistance mechanisms against genetically modified insecticidal pest-resistant crops. Transgenic crops express Bt genes which produce insecticidal proteins (Bt toxins) and provide pest control; however, widespread and long-term planting of Bt crops makes pest resistance more probable because it increases pest exposure to Bt toxins in space and over ...
MALB can be seasonal pests in and around homes and other buildings, particularly in the fall and early spring (Figure 6). Most lady beetle species spend the winter as adults congregated in protected locations. When one lady beetle lands, many others soon follow. Studies conducted on MALB as well as other lady beetles have shown that this aggregation behavior involves temperature, visual and chemical cues (2).. Research in Ohio (3) showed that MALB adults are prompted to search for overwintering sites on the first day over 64°F after a significant drop in temperature, usually to near freezing. Such conditions are usually observed in Ohio sometime in mid- to late October.. In their native habitat, large MALB aggregations often hibernate (overwinter) in cracks and crevices within rock cliff faces. Indeed, studies have shown that MALB is attracted to surfaces covered in highly contrasting vertical black and white stripes (4). Unfortunately, in North America, these foreign lady beetles sometime ...

Blister beetles are out now, but rarely reach damaging numbers in alfalfa. In addition, the beetles feed on clover, soybean, potato, tomato, and eggplant, and are especially attracted to flowers. Like the Japanese beetle, feeding by a few blister beetles draws in more. Large numbers of beetles can cluster on small patches of flowering plants in an otherwise uninfested field. This can result in infested hay. Blister beetles contain cantharadin, a chemical that is very toxic to horses. Fortunately, these insects have not been a significant problem in Kentucky alfalfa fields.

Laboratory Tests. Harmonia axyridis adults were obtained from a laboratory colony established from adults collected during October 2004 at the University of Minnesota Outreach, Research, and Education (UMORE) Park, Rosemount, MN. Following collection, beetles were held in 1.96-liter plastic dishes with ~200 beetles per dish, and maintained at 10 1 C and a photoperiod of 16:8 (L:D) h. Prior to experimentation, the dishes containing beetles were warmed to 25 1 C with a photoperiod of 16:8 (L:D) h (these rearing conditions were used throughout the rest of the studies), and the beetles were allowed to mate for 14 days. Beetles were provided an ad libitum supply of live soybean aphids, Aphis glycines Matsumara, a diet made from freeze-dried honey bee, Apis mellifera L., drone pupae (6), and water in 0.5-ml plastic microcentrifuge tubes plugged with cotton. After the mating period, adult females were maintained individually in plastic Petri dishes (60 mm 15 mm) lined with 55-mm filter paper disks. The ...
The Asian Longhorned Beetle (ALB)(Anoplophora glabripennis) is an invasive beetle believed to have arrived in New York from its native China via untreated packing crates and wooden pallets. Infestations have been discovered in Brooklyn, Queens, Manhattan, and Staten Island.. Tunneling by ALB larvae damages the vascular system of the tree. Repeated attacks lead to dieback of the tree crown, and, eventually, death of the tree. The beetle presents a serious threat to the trees of New York City and has also infested parts of Long Island, Chicago, Ohio, Massachusetts, and New Jersey.. The beetles are known to attack maple, horsechestnut, elm, willow, birch, poplar, and ash trees. Currently the only effective means to control the beetle is to remove infested trees and destroy them by chipping or burning. To prevent further spread of the insect, quarantine zones have been established to avoid transporting wood from the infested areas.. Early detection of infestations and rapid tree removal are crucial ...
Amy Gannon, hatchet in hand, sliced a slab of bark from a lodgepole pine tree near Wolf Creek, Mont., and quickly spotted a mountain pine beetle larva no bigger than her pinky fingernail. "This trees done for," said Gannon, an entomologist with the Montana Department of Natural Resources and Conservation. As wildfires roar through tinder-dry forests in California, the mountain pine beetle is silently killing even more trees -- hundreds of thousands of acres of towering trees, mostly lodgepole pine, according to Robert Mangold, director of Forest Health Protection for the U.S. Forest Service. An epidemic of this magnitude hasnt been seen in the Mountain West in 25 years, he said. In 2007, the beetles were blamed for killing 3.9 million acres of trees in Colorado, Montana, Wyoming, Oregon, Idaho, Utah and Washington, Mangold said. By comparison, the fires in California had burned 640,847 acres as of July 14 this year, according to the National Interagency Fire Center. An average of 3.4 million ...
Sexual conflict can lead to antagonistic coevolution between the sexes, but empirical examples are few. In this thesis secondary sexual characters in diving beetles are interpreted in the light of sexual conflict theory. Whether the male tarsal suction cups and female dorsal modifications are involved in a coevolutionary arms race is tested in two ways. First eight populations of a species with dimorphic females that varied in frequency of the morphs were investigated and male tarsal characteristics quantified. The frequency of female morphs is shown to be significantly correlated to the average number and size of male tarsal suction cups in the population, a prediction of the arms race hypothesis. Second, the hypothesis is tested in a phylogenetic perspective by optimizing the secondary sexual characters on a phylogeny. A full taxonomic revision of the genus Acilius is presented, including new synonyms, lectotype designations, geographic distributions based on more than five thousand examined ...

Beyond Pesticides, August 1, 2011) After sighting three Japanese beetles in the vicinity of Greenback Lane and Fair Oaks Boulevard in Sacramento County, California, state officials are scheduled to spray pesticides linked to cancer, reproductive and neurological effects. On August 2, the California Department of Food and Agriculture (CDFA) is scheduled to begin ground applications of carbaryl on fruit-bearing trees, and cyfluthrin on non-fruit-bearing trees and landscape plants in attempts to stave of attacks from the voracious Japanese beetle. Japanese beetles, a threat to turf grass as well as ornamental plants such as roses and cut flowers, have been detected in the Fair Oaks area, state officials said, but the "˜infestation appears to be localized. To keep the "˜infestation from spreading countywide, Juli Jensen, Acting Agricultural Commissioner, is urging residents in the area not to move plants or plant parts. The initial treatments will be directed at adult beetles and begins August 2 ...
Bark Beetle a consistent negative in a coniferous forest in North America. https://en.wikipedia.org/wiki/Bark_beetle. The 1940-1950s foresters considered the Western United States conifer forests had a 350 year window of healthy to sick-dying cycle. Not all at once but piecemeal thrive and die-burn. Bark Beetle played a role. Sir Frances Drake on a seaborne exploration voyage noted large standing smoke columns in the interior of California. Speculation is plenty, man made fire or nature fire?? Both?. Bark Beetle bores egg holes. Tree if healthy plenty of nutrients, water is a major one that may/can change seasonally, along with chemical nutrients produce sap. This sap in a good year will plug the egg bore hole and kill the eggs-hatch. Bark beetles are always present. Good tree growth years the sap keeps the beetle damage in a state of neutral, low spread damage. Significant Cold helps this natural defense.. Dry years-droughts will allow wide spread bark beetle damage. During the 50s-60s ...
beetle - Click Beetles - Click beetles (family Elateridae) are small to medium-sized beetles with elongated, flattened bodies that have bluntly rounded ends. The largest species reach lengths of about 2 inches (5 centimeters). The larvae of click beetles, called wireworms, cause extensive crop damage in some areas because they feed on underground roots, seeds, and stems. There are about 7,000 species in the click beetle family.
Since its 1916 introduction on a shipment of shrubs from the Far East to New Jersey, the Japanese beetle (Popillea japonica Newman) has become a scourge to gardeners throughout the U.S. It has been contained better in California than in many other parts of the country, but it is still capable of inflicting serious and widespread damage here.. When it arrived on U.S. shores, it was greeted by a very hospitable environment: no natural enemies, a suitable climate, some 300-350 host species for adult beetles to feed on, and ample pasture and turf in which the grubs could develop. These conditions allowed the Japanese beetle to become well-established and widespread. Favored hosts for the adult have included apples, lindens, Japanese and Norway maples, roses, crape myrtle, birches, various stone fruit (prunus spp.) and grapevines.. The adult beetle is about -3/8 inch long with a metallic green body, coppery wing covers and six pairs of white tufts on the wings margins that help distinguish it from ...
Yes there are millions of acres of beetle killed pine trees in Colorado, but also Wyoming, Utah, Idaho, Montana, eastern Oregon and Washington, New Mexico, British Columbia, Alberta and the Yukon. Local politicians respond to local demands to do something, but rarely do they realize or at least tell their constituents that that beetle kill is unstoppable by humans. The pine trees over hundreds of thousands of square miles are vulnerable to attack due to their age, but more due to winters failure to have sustained cold temperatures below -20 F.. I have never seen a large pine bark beetle infestation stopped anywhere by human means. I have been following mountain pine beetle kills since 1974 when I was first hired as consultant on the Targhee National Forest to help with the big mountain pine bark beetle infestation there, west of Yellowstone Park. The current infestation is much large, it almost spans the Continent from north to south.. As far as the alledged fire danger of vast tracts of dead ...

Hans-Jürgen Stammer (1899-1968) studied symbiotic partnerships between insects and bacteria during the 1920s and 30s. He found that leaf beetles (Chrysomelidae) are notorious for not partaking in symbiotic partnerships. However, his studies also revealed that there were exceptions to this finding among some tortoise beetle species, such as the thistle tortoise beetle (Cassida rubiginosa). These tortoise beetles are equipped with unusual organs, which he described in a 1936 study. The symbiotic bacteria reside in sac-like reservoirs in the guts of the beetles. Female beetles transfer the symbionts through vaginal tubes to their offspring by applying a tiny symbiont caplet to each egg. The hatching larvae eat through the egg shell and then consume the caplets containing the symbiotic bacteria. Leaf beetles are able to degrade components of the plant cell wall, such as cellulose and pectin, with the help of digestive enzymes. However, genetic analysis showed that the thistle tortoise beetle lacks ...
We took samples back to the lab and carefully inspected the larvae under a microscope. Using a dichotomous key, I was able to name the organisms down to genus. They were first instar larvae of the blister beetle (Meloe sp.). Now what on earth is a blister beetle and why is it hitching a ride on these bees? Is it harmful to bees? Could this be a new pest?. We did some investigating to find out. It turns out that blister beetle larvae are previously reported on bees and other pollinators in the US. Larvae of some Meloe species grab hold of pollinators while on flowers. In fact, theres a range of pollinators they attach to: solitary bees, wasps, flies, beetles…and honey bees. Some species parasitize bees by feeding on hemolymph, but their main purpose for interacting with pollinators remains a mystery. The fact that phoretic larvae use such a wide range of pollinators doesnt support the idea that they are using honey bees as hosts to parasitize. Researchers think that these larvae might be ...

Perhaps predictably, the beetles were also patchily distributed, with most individuals occurring near each other, leaving large stretches of fire lane beetle-free. I spent some time pondering what might account for this - warm microclimate? Wetter or drier soils? Exposure to sun? - but found no ready explanation. Both species overwinter in burrows which, published sources say, may be as deep as two or three feet. Possibly conditions in certain spots discourage the deepest burrowing, leaving some hibernating beetles closer to the surface and more likely to be affected by transient warmth than others.. You might expect a February tiger beetle to be a bit groggy, given that it spent the previous five months or so chilled and nearly immobile in an underground burrow. But youd be wrong. Both species were feisty, active, and wary, difficult to approach and flying high, fast, and far when flushed; my impression was that the oblique-lined tiger beetles, at least, were more active than Id expect them ...
Z)-6-Nonen-2-one (1) has recently been shown to be the biosynthetic precursor for the aggregation pheromone exo-brevicomin (2) in mountain pine beetle (MPB) males, Dendroctonus ponderosae (Hopkins). We tested the hypotheses that (1) 6-methyl-6-hepten-2-one (3) is the biosynthetic precursor for the aggregation pheromone frontalin (4) in the spruce beetle (SB), Dendroctonus rufipennis (Kirby), and (2) that frontalin and exo-brevicomin are produced from 3 and 1, respectively, only by beetles that utilize them as aggregation pheromones. Exposure of scolytids MPB, SB, pine engraver (PE), Ips pini (Say) and Ips tridens (Mannerheim) and West Indian sugar cane weevil (WISW), Metamasius hemipterus sericeus (Olivier) to deuterio- or protio-3 invariably resulted in the production of deuterio- or protio-4. Similarly, exposure of SB, WISW and I. tridens to 1 resulted in the production of 2. We were unable to demonstrate the presence of 3 in SB volatiles, nor were we able to demonstrate the conversion of ...
CUCUMBER BEETLES ON MY POTATOES and TOMATILLO?. No. Those are not cucumber beetles. Potatoes, tomatoes, tomatillos, and sometimes eggplants are attacked by this pest that only superficially looks like a cucumber beetle. This is the THREE-LINED POTATO BEETLE. The adult of this pest is about the same size as a cucumber beetle but has a reddish head and a thorax with two dark spots. The wing covers are dark yellow with three black stripes. Its favorite food in my experience is tomatillo.. The Three-Lined Potato Beetle overwinters as an adult and wakes early in the spring. They are there waiting for you to plant your solanaceous crops. The females soon begin laying eggs that hatch in about two weeks to larvae that look a bit like Colorado potato beetle larvae, except these critters have the endearing practice of carrying a small pile of their own excrement on their back. The larvae mature in about two weeks. There are probably two generations per year.. On most crops the level of the pest does not ...

[more ▼]. The multicoloured Asian ladybird Harmonia axyridis Pallas (Coleoptera: Coccinellidae), previously introduced as a biological control agent to control aphids populations, is now frequently considered as an intraguild predator, consuming other aphids natural enemies. The interactions between this exotic ladybird and other aphidophagous species present in Belgian agro-ecosystems are mainly asymmetric in support of H. axyridis. An aphidophages sampling has been performed between 2009 and 2011 in four agrosystems such as broad bean, wheat, corn and potato. The sampling method consisted in the counting of aphids and all developmental stages of aphidophages present in quadrats of 1m² from April to September. Harmonia axyridis, the invasive coccinellid, was ...

Applications of Metarhizium brunneum Petch (Ascomycota: Hypocreales: Clavicipitaceae) isolate LRC112 conidia caused high mortality to Agriotes obscurus L. (Coleoptera: Elateridae) click beetles in field trials. Banded conidiated rice (4.4 × 1014 conidia ha−1) and conidia dust (5.0 × 1013 conidia ha−1) resulted in 93.3 % ± 7.3 and 91.3 % ± 3.0 mortality after 18 days, while aqueous conidia suspension spray (5.0 × 1013 conidia ha−1) with and without 80 g ha−1 spinosad resulted in 68.2 % ± 17.7 and 52.6 % ± 17.4 mortality. Differences in results between 2012 and 2013 were attributed to rainfall, with pronounced effects in 2012 (rain beginning 35 h post treatment) and minimal effects in 2013 (rain beginning at 4 h). In another field experiment, beetles dosed with 1.49 × 107 ± 5.08 × 106 conidia per beetle retained 4.6 % of conidia after seven days while conidia viability on beetle bodies remained unchanged. The results inferred opportunities for controlling click beetles using ...
3] mottling. The main vector of BPMV is the bean leaf beetle, Cerotoma trifurcata (Forster). An experiment was conducted in 2000 and 2001 at two locations in northwestern and central Iowa to test three insecticide treatments for suppression of bean leaf beetles, and subsequently, BPMV. Treatments of insecticide applications with lambda-cyhalothrin were 1) a single early-season application (23 g [AI] /ha) (2.5 oz/acre) at the VE-VC soybean developmental stage; 2) two early-season applications, the first the same as treatment I and a second at the same rate 9-13 d later; 3) a single early-season application the same as treatment 1. followed by a mid-season application (28 g [AI] /ha (3.2 oz/acre) at approximately R2 (flowering, near 15 July); and 4) an unsprayed control. Application of lambda-cyhalothrin after soybean emergence and again as first-generation bean leaf beetles emerged in northwestern Iowa in 2000 (treatment 3) significantly reduced beetle densities through mid-season, BPMV field ...

Faunal Associations: In North America, many kinds of insects are known to feed on the foliage, wood, and other parts of Austrian Pine (Pinus nigra). These species include Tomicus piniperda (Common Pine Shoot Beetle), Pilophorus gracilis (a plant bug) and other plant bugs, Eulachnus rileyi and other aphids, Chionaspis pinifoliae (Pine Needle Scale) and other armored scales, and the larvae of Dioryctria zimmermani (Zimmerman Pine Moth) and other moths (Cranshaw, 2004; Wheeler et al., 1983; Blackman & Eastop, 2013; ScaleNet, 2014).

ANNAPOLIS, MD (December 2, 2007) - Beginning in 2003, reports surfaced of dying redbay trees (Persea borbonia) in coastal areas of Georgia and South Carolina; in 2005 the problem was also found in northeast Florida. Further study confirmed that the cause was a previously unknown fungus in the same genus as Dutch elm disease, Ophiostoma. The pathogen is transported by a recently introduced ambrosia beetle from Asia, Xyleborus glabratus, which first was detected in the U.S. in 2002 near Port Wentworth, Georgia. Currently, infestations have been detected in more than 30 counties in coastal Florida, Georgia and South Carolina. Because redbay is an endangered plant in Maryland and this pathogenic fungus and its vector beetle are red alert species for us, the Maryland Invasive Species Council has chosen them as the December Invader of the Month. Redbay is a common understory tree in the coastal plain, distributed primarily from Virginia s far southeast corner to the Mississippi-Louisiana border. In ...
This study addressed the possible behaviora induction effects of previous exposure to several specific host plants on subsequent host preference hierarchy and specificity (i.e .. how far down the ranking order a female will go) the most polyphagous swallowtail butterfly in the world, Papilio glaucus (Papilionidae). Multi-choice preference bioassays using individual females in revolving arenas were used to assess one of the potentially most significant non-genetic sources of variation: learned (or induced) oviposition preferences. Results of the 4-choice studies using tulip tree (Liriodendron tulipifera; Magnoliaceae), black cherry (Prunus serotina; Rosaceae), quaking aspen (Populus tremuloides; Salicaceae), and hoptree (Ptelea trifoliata; Rutaceae), fail to show any significant oviposition preference induction with two-day prior exposure to any of the host species tested. It appears that the eastern tiger swallowtail butterfly, while polyphagous as a species (feeding on more than 9 families of
Vinegar flies (Drosophila melanogaster) and nitidulid beetles (Carpophilus hemipterus and C. freemani) captured in peach and nectarine orchards in California were found to be contaminated with Mucor piriformis, Rhizopus stolonifer, Monilinia fructicola, Cladosporium spp., Penicillium spp., and other species of Mucor. D. melanogaster and Carpophilus spp. acquired propagules of M. piriformis and transferred them to 75 100% of injured peach fruit. In general, C. hemipterus transmitted M. piriformis to wounded fruit more efficiently than C. freemani. Propagules of M. piriformis persisted for at least 15 days on D. melanogaster and 11 days on C. hemipterus. Only the nitidulid beetles transmitted the fungus to uninjured peach fruit, causing fruit rot on 42 75% of uninjured fruit.. ...
Corn flea beetles, Chaetocnema pulicaria, vector Erwinia stewartii (synamorph Pantoea stewartii), which causes Stewarts bacterial wilt of corn (Zea mays). A seed treatment insecticide, imidacloprid, killed flea beetles and reduced the number of feeding wounds and Stewarts wilt symptoms per leaf in greenhouse studies. The objective of our research was to evaluate the ability of imidacloprid and thiamethoxam seed treatments to control Stewarts wilt on sweet corn hybrids under field conditions with naturally occurring populations of the corn flea beetle. Six field trials were planted at four locations in 1998. Eleven field trials were planted at nine locations in 1999. The treatment design was a factorial of sweet corn hybrids and seed treatments. Stewarts wilt incidence ranged from 0 to 54% in the 1998 trials. Incidence of Stewarts wilt in nontreated plots of the susceptible hybrid Jubilee ranged from 2% at the 8-leaf stage to 77% 1 week after mid-silk in the 1999 trials. Seed treatment ...
Although terrestrial lichens and bryophytes are common in upland plant communities of the Blue Mountains in northeast Oregon, research on cryptogam communities in this region is wanting. Studies have shown that lichens and bryophytes can reduce soil erosion and increase soil fertility in other semiarid habitats of North America. Understanding the particular roles terrestrial lichens and bryophytes play in their ecosystems and how they react to anthropogenic disturbances is part of making sound management decisions. Managers in the Blue Mountains are now dealing with heavy fuel loads in forested habitats that were impacted by mountain pine beetles, western spruce budworm infestations, Douglas fir dwarf mistletoe, and drought from the 1970s into the 1990s. To better understand how cryptogam communities respond to fuels reduction treatments in insect impacted Abies grandis classified forests of the central Blue Mountains, we compared species composition of logged and burned stands to stands that ...
