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 ...
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.. Additional information for reporting of any findings and photos and information about the Colorado potato beetle may be found on Eviras web pages at the address: www.evira.fi/koloradonkuoriainen.

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 ...
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 ...

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 ...

This shows a micro-CT scan of a live, one-week-old male Colorado Potato Beetle. It was placed in a sort of suspended animation using carbon dioxide, was scanned using a micro-CT scan and then recovered fully.
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.. ...

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, ...
