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)

The Colorado potato beetle (Leptinotarsa decemlineata (Say)) is a significant pest of potato plants that has been controlled for more than two decades by neonicotinoid imidacloprid. L. decemlineata can develop resistance to this agent even though the molecular mechanisms underlying this resistance are not well characterized. MicroRNAs (miRNAs) are short ribonucleic acids that have been linked to response to various insecticides in several insect models. 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 ...

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..

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, ...

We are ready to research the Bornean Firefly Larva, though we cannot discount that it might be a Netwing Beetle Larvae. Eric Eaton says the way to tell the difference it to introduce a snail. If the beetle larva eats the snail, it is a Firefly Larva. If it prefers fungus, it is a Netwing Beetle Larva. We imagine that there may also be snail and fungus specificity in the preferences. Here is an example from The Flying Kiwi of a Larviform female Netwing Beetle from Viet Nam, and here is another example of a Netwing Beetle and The Flying Kiwis, AKA Richard Seamans, written account: I didnt notice that this one in Malaysia was glowing, but it turns out that both this and the Vietnamese firefly arent fireflies at all, theyre actually the larvae of net-winged beetles in the genus Duliticola, otherwise known as trilobite larvae because of their prehistoric shape; the one you see here is Duliticola hoiseni. The drops of liquid on this ones back look like they are some toxic substance exuded ...
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 ...
Typical for the ancient beetle suborder Adephaga to which they belong, they have paired pygidial glands in the lower back of the abdomen. These are well developed in ground beetles, and produce noxious or even caustic secretions used to deter would-be predators. In some, commonly known as bombardier beetles, these secretions are mixed with volatile compounds and ejected by a small combustion, producing a loud popping sound and a cloud of hot and acrid gas which can injure small mammals, such as shrews, and is liable to kill invertebrate predators outright. To humans, getting bombed by a bombardier beetle is a decidedly unpleasant experience. This ability has evolved independently twice as it seems - in the flanged bombardier beetles (Paussinae) which are among the most ancient ground beetles, and in the typical bombardier beetles (Brachininae) which are part of a more modern lineage. The Anthiini, though, can mechanically squirt their defensive secretions for considerable distances and are ...
Yoon JS, Kim K, Palli SR. 2020. Journal of Asia-Pacific Entomology. 23(4):1160-1164.. Despite extensive research during the past decade elucidating the mechanism of RNA interference (RNAi) in insects, it is not clear how ingested or injected double-stranded RNA (dsRNA) triggers RNAi response in the whole body or even its progeny, which is referred to as systemic RNAi. In the present study, we aim to understand how the dsRNA delivered into cells causes systemic RNAi using Colorado potato beetle cells (Lepd-SL1). We first tested if dsRNA treatment induces systemic RNAi in Lepd-SL1 cells. Exposure of a new batch of Lepd-SL1 cells to the conditioned medium where Lepd-SL1 cells treated with dsRNA targeting inhibitor of apoptosis were grown for 6 h induced apoptosis in these new batch of cells. We hypothesized the exosomes in the conditioned medium are responsible for RNAi-inducing effect. To test this hypothesis, we isolated exosomes from the conditioned medium from Lepd-SL1 cells that had been ...

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.. ...
Booking a place is required to attend - this ensures equipment and resources will be available.. Mark Telfer (Bedfordshire) and John Walters (Devon). The seventh annual ground beetle workshop will help beginners and experts alike to find and identify British and Irish carabids. The programme will start with a brief talk covering new topics of interest, followed by an identification session helping beginners to identify carabids to genus, as well as providing tuition on some of the more difficult genera for more advanced carabidologists. We can cover the key techniques (carding, dissection, and handling carabids for field identification) and cover any identification problems, with a little prior notice.

Adults spend the winter buried 8 to 10 inches deep in the soil, emerging in time to feed on the first foliage of early potatoes. They are wide, convex beetles, 1/2″ long, with alternating black and yellow stripes. Females lay up to 20 batches each of orange-yellow eggs in groups on the underside of the leaves, over 4 to 5 weeks. The eggs hatch into humpbacked, purplish-red larvae, with 2 rows of black dots along each side. These larvae eat voraciously, often entirely consuming the leaves. When full-grown they descend into a spherical cell in the ground, transform to a yellowish pupa, and in 5 to 10 days new adults emerge to feed and lay eggs for the second generation..

Agriculture scientist Dr Matthew Cock, chief scientist for Cabi, a UK-based agri-environment research organisation, lists some of the biggest biological threats to global food security. Pests like desert locust, western corn root worm (Diabrotica virgifera virgifera), the Khapra beetle (Trogoderma granarium), mountain pine beetle (Dendroctonus ponderosae) and colorado potato beetle (Leptinotarsa decemlineata) are suggested together with plant diseases, causing famine in the past: potato blight (Phytophthora infestans), or big economic losses in agricultural production: wheat stem rust strain Ug99 (Puccinia graminis tritici), South American rubber blight (Microcyclus ulei) and cofee wilt disease (Fusarium xylarioides).The original article (BBC News) was cited also by IPM in the South (18 Jan 2012).

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 ...

Leptinotarsa decemlineata is a common pest of solanaceae crops, especially potato, but also eggplant, tomato, pepper and tobacco. The adults appear from hibernation in May, feed on young leaves for 5-10 days, mate, and then immediately start with oviposition. Over a period of 4-5 weeks, each female lays up to ca. 1,000 eggs in clusters of 20-50 on the undersides of leaves. The larvae hatch 3-14 days later. They molt three times, and the four larval instars last 2-4 weeks. The larvae drop to the soil where they build a round cell up to 20 cm deep to pupate there. Pupation lasts a further two weeks, but the completely-developed beetles stay in the soil at least one more week before emerging. Only a few of them use their ability to fly to find new food sources. There are 1-3 generations each year. In October, the adults burrow 20-40 cm (7.87 - 15.75 inch) deep into the soil, where they overwinter.. ...
Although Japanese beetles havent been found in West Vancouver, the District is aware that they have been found in other areas of the Lower Mainland and staff are keeping watch.. Green and yellow torpedo traps have been set up throughout Metro Vancouver, including in West Vancouver, by the Canadian Food Inspection Agency (CFIA). Please do not tamper with these traps.. Japanese beetles are an invasive species that can cause significant damage compared to other pests, such as European chafer beetles. Adult Japanese beetles eat foliage and fruit of more than 250 kinds of plants, and can impact gardens and agricultural crops. Larvae feed on the roots of lawns and other plants.. The first live Japanese beetle in Vancouver was discovered in a CFIA trap near False Creek in 2017. Beginning in February 2019, an expanded containment area was established to limit the movement of soil and plant material in areas around False Creek, downtown and Stanley Park.. ...
This is the pupa of a Lady Beetle. Insects that undergo metamorphosis have two active stages, the larva and the imago or adult, and two inactive stages, the egg and the pupa. When the weather conditions are right and the proper amount of time has elapsed, this pupa will metamorphose into an adult Lady Beetle or Ladybug. This appears to be the pupa of a Multicolored Asian Lady Beetle, Harmonia axyridis, an introduced species, and you can compare your image to the photos posted to BugGuide. Your third photo (the second in our posting) is the larva of the Multicolored Asian Lady Beetle.. ...

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 ...
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 ...

The tree-killing mountain pine beetle (Dendroctonus ponderosae Hopkins) is an important disturbance agent of western North American forests and recent outbreaks have affected tens of millions of hectares of trees. Most western North American pines (Pinus spp.) are hosts and are successfully attacked by mountain pine beetles whereas a handful of pine species are not suitable hosts and are rarely attacked. How pioneering females locate host trees is not well understood, with prevailing theory involving random landings and/or visual cues. Here we show that female mountain pine beetles orient toward volatile organic compounds (VOCs) from host limber pine (Pinus flexilis James) and away from VOCs of nonhost Great Basin bristlecone pine (Pinus longaeva Bailey) in a Y-tube olfactometer. When presented with VOCs of both trees, females overwhelmingly choose limber pine over Great Basin bristlecone pine. Analysis of VOCs collected from co-occurring limber and Great Basin bristlecone pine trees revealed only a few
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 ...

ABSTRACT During periods with epidemic mountain pine beetle ( Dendroctonus ponderosae Hopkins) populations in lodgepole pine ( Pinus contorta Dougl. ex Loud. var. latifolia Engelm.) forests, large amounts of tree foliage are thought to undergo changes in moisture content and chemistry brought about by tree decline and death. However, many of the presumed changes have yet to be quantified. In this study, we quantified and compared fuel moisture, chemistry, and resulting flammability of bark beetle affected foliage in terms of ignitability, combustibility, consumability, and sustainability at a site in far eastern Idaho, USA. Results revealed substantial decreases in moisture content, the proportion of starches and sugars, and crude fat and increases in the proportions of lignin, cellulose, and hemicellulose in foliage of trees attacked in the previous year (yellow foliage) or more than two years previously (red foliage). Increases in emission rates of several terpenes that were correlated with

The mountain pine beetle (Dendroctonus ponderosae Hopkins) (MPB) has infested and killed millions of hectares of lodgepole pine (Pinus contorta var. latifolia Engelm) forests in British Columbia, Canada, over the past decade. It is now spreading out of its native range into the Canadian boreal forest, with unknown social, economic and ecological consequences. This review explores the ramifications of the MPB epidemic with respect to mid-term timber supply, forest growth, structure and composition, vegetation diversity, forest fire, climate change, and ecosystem resilience. Research confirms that, in British Columbia, all of these variables are more significantly impacted when salvage logging is used as management response to the outbreak. We conclude that appropriate management in response to MPB is essential to ensuring ecologically resilient future forests and reliable mid-term timber supplies for affected human communities. We highlight knowledge gaps and avenues for research to advance our
Recent wildfires in mountain pine beetle (Dendrocronas ponderosae; MPB) post-outbreak lodgepole (pinus contorta var. latifolia) stands in the western United States have generated concern among stakeholders and disagreement over predicted fire behavior in the scientific literature.

Twelve MPB post-outbreak wildfires and one prescribed fire were ...
TY - JOUR. T1 - Early detection of Agrilus planipennis. T2 - investigations into the attractive range of the sex pheromone (3Z)-lactone. AU - Parker, Katie. AU - Ryall, Krista. AU - Aukema, Brian H.. AU - Silk, Peter. PY - 2020/2/1. Y1 - 2020/2/1. N2 - The emerald ash borer (EAB), Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), is a highly destructive primary pest of ash (Fraxinus sp., Oleaceae) trees outside of its native range. Ash is an important component of many ecosystems and its loss would be detrimental to both the economy and the environment. The present study aimed to improve our understanding of the effectiveness of green sticky prism traps baited with host kairomone and insect pheromone lures for A. planipennis and to collect data for modelling the range of attraction of the pheromone (3Z)-dodecen-12-olide [(3Z)-lactone]. Traps were deployed over a single flight season in urban locations of Ontario, Canada, with low densities of EAB. Traps were placed in pairs of trees ...
The emerald ash borer has more effective dispersal than any invasive forest insect weve yet had to face, and attacks all of the ash species in our region (white, black, and green ash). And there is not yet strong evidence that any individuals of particular ash species have immunity. Unlike the hemlock wooly adelgid, whose northern range limit is currently restricted by cold winter temperatures, the climatic range of the ash borer includes all of northeastern North America. Dutch elm disease virtually eliminated American elm from its preferred habitat (forested swamps), but elms also occur as isolated trees in upland forests, and the beetle that spreads the disease isnt 100% successful at finding those isolated trees, so elms have persisted (at low numbers). But black ash is really only found in swamps, and given the dispersal ability of the emerald ash borer, the situation is bleak. There were extensive (and expensive) efforts to control and eradicate the insect when it was first discovered in ...

Emerald ash borer in Canada was first detected in 2002, in Windsor, Ontario. By 2005, it had spread into Essex and Lambton counties and the municipalities of Chatham-Kent and Dutton/Dunwich. In 2006, it was detected in London, Ontario; and in 2007, as far east as Toronto. The insect has continued to spread in that province since, with infestations appearing as far north as Sault Ste. Marie and as far east as Ottawa and Prescott-Russell and Leeds-Grenville counties. In 2013, the beetle was detected in Frontenac County, Simcoe County, Peterborough County, the District of Algoma, and Manitoulin Island.. The presence of emerald ash borer in Quebecs Montérégie area was confirmed by the Canadian Food Inspection Agency (CFIA) in 2008. Infestation in Montreal and the Gatineau area were detected in 2011; Longueuil in 2012; and Terrebonne in 2013.. In 2014, CFIA consolidated the regulated areas within Ontario and Quebec into one larger regulated area.. All of these areas are regulated by federal ...

APHIS is proposing to remove the domestic quarantine regulations for the emerald ash borer (EAB). Eliminating this regulation is in keeping with USDAs goal of reducing regulations that have outlived their usefulness. The proposal would end APHIS domestic regulatory activities, which includes actions such as issuing permits, certificates and compliance agreements, making site visits, and conducting investigations of suspected violations, and instead direct all available resources toward managing the pest. APHIS remains committed to controlling this invasive pest and wants to conduct more research and release a greater number of biological control agents-tiny stingless wasps that are natural predators of the EAB-since biocontrol has shown the most promise for stopping EABs spread.. The open comment period for the proposed rule to remove the domestic quarantine regulations for the emerald ash borer (EAB) closed on November 19, 2018.

The tiny larvae of the willow leaf beetle, no bigger than this i, defend their feeding grounds from competitors such as hulking caterpillars -- thousands of times heavier -- by using a kind of chemical warfare, a University of Maryland entomologist has discovered.. Normally the beetle larvae spend their days quietly munching weeping willow leaves. When a major competitor nears, however, special glands in the larvas body exude an aromatic substance onto the leaf. One whiff induces such a powerful response in the caterpillars that they immediately vomit and crawl away.. You can find these beetle larvae on weeping willow trees all over the Washington area and smell the chemical for yourself, said Michael J. Raupp, the scientist. To me it smells kind of pleasant, sweet. But to the caterpillars its an irritant, and they give the barf response.. Raupp learned how the beetles defenses work by bringing some into the laboratory, letting them feed on willow leaves and introducing caterpillars. He ...
A new University of Colorado Boulder study shows for the first time that episodes of reduced precipitation in the southern Rocky Mountains, especially during the 2001-02 drought, greatly accelerated development of the mountain pine beetle epidemic.

Background/Question/Methods. In 2014, Cipollini discovered that the ash-killing emerald ash borer, Agrilus planipennis, was capable of feeding and completing development on white fringetree, Chionanthus virginicus, a native North American tree that is used as an ornamental. Subsequent studies have revealed that this phenomenon is widespread and may be due to shared chemical characteristics of white fringetree with susceptible ash species. Given its ability to use white fringetree, we have been examining other close relatives for their susceptibility to emerald ash borer, with potentially important implications for the spread, impacts, and persistence of emerald ash borer in North America and beyond. In this study, we examined the susceptibility of cultivated olive, Olea europaea, to emerald ash borer, Agrilus planipennisin a series of controlled laboratory tests. Cultivated olive is a Mediterranean native that is grown in the southeastern and western U.S. It will be contacted by emerald ash ...

DEP And Connecticut Agricultural Experiment Station Respond To Presence Of Asian Longhorned Beetle In Worcester, MA Abstract: The Connecticut Department of Environmental Protection (DEP) and the Connecticut Agricultural Experiment Station (CAES) today announced that federal agricultural officials have confirmed the presence of the Asian Longhorned Beetle (ALB) in nearby Worcester, Massachusetts.
On July 23, 2008, USDA scientists discovered seven emerald ash borer beetles (Agrilus planipennis) in traps in Wayne County at a campground located at the U.S. Army Corps of Engineers Greenville Recreation Area near Wappapello Lake in southeast Missouri.. The emerald ash borer is an aggressive wood-boring insect that attacks and kills all species of ash (Fraxinus) trees. Attacks by this metallic-colored beetle of the Buprestidae family usually kill ash trees in one to three years. Although stressed trees are usually more prone to borer attack than healthy trees, evidence from Michigan suggests that even healthy, well-maintained ash trees are being attacked and killed by this beetle.. The natural range of the emerald ash borer is eastern Russia, northern China, Japan and Korea. It was first discovered in North America in Michigan in June 2002. The borer most likely traveled from Asia to North America in wooden packing materials. Because adult insects only move short distances on their own, the ...
Blister beetles produce cantharidin, a poisonous substance comparable to cyanide and strychnine in toxicity. Stored in the insects blood, the compound is stable and remains toxic even in beetle carcasses. Animals may be poisoned by ingesting beetles while grazing or eating harvested silage. Cantharidin can also cause severe skin inflammation and blisters.. Cantharidin is absorbed through the intestine and can cause symptoms such as inflammation, colic, straining, elevated temperature, depression, increased heart rate and respiration, dehydration, sweating, and diarrhea. There is frequent urination during the first 24 hours after ingestion, accompanied by inflammation of the urinary tract. This irritation may also result in secondary infection and bleeding. Taken internally, as little as 10 milligrams can be fatal in humans.. The concentration of cantharidin in adult beetles depends primarily on the sex; males produce the chemical and only pass on small amounts to the females during mating. ...

Pitfall traps were used to sample beetles (Coleoptera) in plots with or without inputs of dead loblolly pine (Pinus taeda L.) wood at four locations (Louisiana, Mississippi, North Carolina and Texas) on the coastal plain of the southeastern United States. The plots were established in 1998 and sampling took place in 1998, 1999, and 2002 (only 1998 for North Carolina). Overall, beetles were more species rich, abundant and diverse in dead wood addition plots than in reference plots. While these differences were greatest in 1998 and lessened thereafter, they were not found to be significant in 1998 due largely to interactions between location and treatment. Specifically, the results from North Carolina were inconsistent with those from the other three locations. When these data were excluded from the analyses, the differences in overall beetle richness for 1998 became statistically significant. Beetle diversity was significantly higher in the dead wood plots in 1999 but by 2002 there were no ...
Having developed new-and-improved decoys that imitate female invasive insects the Emerald Ash Borer, scientists are hoping to preserve new-growth ash trees, the insects quarry.
The number of recorded intercepts and eradications of khapra beetle (Trogoderma granarium) have increased in Australia and the United States in recent years. Khapra beetle is one of the most destructive stored grain pests, and infestations can destroy the quality of grain and other commodities rendering the product unfit for human consumption. This pest can be easily transported from khapra beetle countries undetected as live beetles, eggs and larvae or in a state of diapause, with the transfer of people and goods around the world. Historically, discovery of khapra beetle post-border has generally resulted in costly eradication programs including methyl bromide fumigation and years of surveillance. Misidentification, failed detection or lack of preparedness has led to slow responses and at times the wide distribution of the pest prior to action. The United States spent over thirteen years (1953 - 1966) eradicating a large scale khapra beetle outbreak that involved fumigation of over 600 sites of
Emerald Ash Borer is a non-native, highly destructive wood-boring beetle that feeds under the bark of ash trees. All species of ash are susceptible to attack, except mountain ash, which is not a true ash species. Since it was first identified in Michigan in 2002, EAB has killed millions of ash trees in Ontario and many parts of the United States. It poses a major economic and environmental threat to urban and forested areas. It was confirmed in Ottawa in 2008 and its impacts can be clearly seen spreading from the St. Laurent area. Since the insect spends most of its lifecycle under the bark of trees, it can be easily moved with firewood or other tree materials such as nursery stock, logs, brush and larger wood chips. This insect is able to fly, but since its spread has been primarily along major highways and transport routes, it is clear that humans are the main vector of dispersal.. ...

Washington, D.C. (January 31, 2005) - Since its discovery near Detroit in 2002, the emerald ash borer has devastated ash tree populations in Michigan, Ohio and Ontario and has been sighted elsewhere.. Now Agricultural Research Service scientists, including those at the ARS Systematic Entomology Laboratory (SEL) in Washington, D.C., and Beltsville, Md., are working to precisely identify parasitic wasps that seem to be natural enemies of this imported metallic-green beetle, Agrilus planipennis Fairmaire. Thought to have arrived here about six years ago, hidden in wooden packing material, the borer is threatening to become a major U.S. pest.. U.S. Forest Service and Michigan State University researchers found the potentially beneficial wasps in a study plot in Livonia, Mich., and sent them to the SEL for identification. There, entomologists Michael Gates and Michael Schauff identified them as species in the genus Balcha, which like to snack on emerald ash borer larvae, and in the genus Pediobius, ...

The emerald ash borer is a very destructive insect pest of ash trees, the only known hosts of this borer in the United States. EAB is a slender, elongate insect about 1/3 - 1/2 inch long. It is widest just behind the head, gradually tapering back to the abdomen. It is a bright iridescent green to copper-green color, often with a copper colored area behind the head. Its body underneath the wings is a purplish-magenta color.
The small hive beetle (Aethina tumida, SHB) is an invasive pest of honey bee (Apis mellifera) colonies in the United States. The adult and larval beetles can ruin honey through fecal contamination and by vectoring a mutualistic yeast (Kodamaea ohmeri) that causes honey fermentation. These beetles also impact honey bee colonies by feeding on bee eggs, bee brood, and pollen. Severe beetle infestations can cause colonies to decline or abscond. The SHB has been present in the United States since at least 1998. Since then, there have been several published papers on how to successfully rear these beetles. Laboratory rearing of SHBs allows for immediate access to adults and immature stages without having to constantly collect them from infested bee colonies. A clean and cost effective method for rearing SHBs is presented in this thesis. There is little published information on the external morphology of the SHB. Murray, Schmolke, Menier, and Jouan were some of the few authors to publish on this subject.
Emerald ash borer (EAB) arrived at the Allegheny National Forest in Pennsylvania in 2012 and has rapidly been killing ash trees across the forest. Northern Research Station scientists, in partnership with State and Private Forestry, the Allegheny National Forest, and other partners, have been working on conserving white ash genetic diversity across the Allegheny. Using population genetic approaches, scientists determined that to optimize conservation of genetic diversity, insecticide application efforts should focus on treating many sites with at least 10 trees per site rather than treating many trees within a single site. The results also highlight how valuable it is to select the correct sites for treatment, with certain sites holding more genetic diversity than others. Performing genetic analyses before insecticide treatment and using that information to select sites with complementary genes can result in nearly a 30 percent cost savings. The results of this research will help forest managers ...
Different research and extension networks will help execute the objectives. Research and technology transfer is facilitated by the coordinated structure of the group. For example, entomologists in NCERA-224 from the states with active emerald ash borer infestations used the NCERA-224 structure to coordinate research objectives and protocols in various states to evaluate insecticides for control of emerald ash borer. They were then well positioned to develop consensus recommendations for managing emerald ash borer, which were subsequently published in the highly cited multi-state NCR-IPM bulletin, Insecticide Options for Protecting Ash Trees from Emerald Ash Borer. More generally, members of NCERA-224 provide information, as appropriate, to clientele and stakeholders through face-to-face meetings, newsletters, CEU trainings, and professional society meetings such as annual meetings of the Entomological Society of America and American Phytopathological Society. Many of the same pests occur in ...
