In its effort to keep cattle fever ticks from escaping quarantine in five counties along the southern Texas border, researchers at the U.S. Department of Agriculture have developed an overnight DNA test that can detect ticks’ genetic indicators of resistance to permethrin, a common pesticide used to manage ticks.
An entomologist examining wasp specimens in fossilized amber from the Eocene (34–55 million years ago) has identified them as a new species, Brachyelatus marthae, and the first fossil specimens from the chalcid wasp subfamily Chrysolampinae.
Wild pollinators have the potential to play a bigger part in pollinating specialty crops, according to a new study.
A new Journal of Insect Science study provides insights into moth and butterfly communication and scale development.
Though tick populations tend to decrease in areas where predatory ants are present, a new study reveals that it's not because the ants prey on the ticks. In fact, predatory ants such as fire ants ignore ticks completely.
In many tick species, more than three-quarters of their lives are spent off-host in the soil or among the leaf litter. A research team at Cornell University highlights an important opportunity for tick researchers and soil ecologists to collaborate to better understand what happens when the ticks aren't in contact with hosts.
A new article in the Journal of Economic Entomology examines varying levels of resistance to Bt toxins developed by the pink bollworm in the United States, China, and India over the last 20 years, illustrating the importance of incorporating refuge crops in Bt systems.
Engineers may recognize the internal muscle structure of a honey bee abdomen for its resemblance to a Stewart platform, a mechanical device that enables six degrees of freedom in movement. Researchers who have found its natural equivalent in bees say the discovery is already informing their work in designing articulating nose cones for rockets.
Integrated pest management comes with a variety of benefits, but its mix of methods can present complicated choices to growers low on resources and agricultural advice. A new report in the Journal of Integrated Pest Management outlines some potential solutions.
Entomologists can find out a lot about an insect through some simple chemical reactions in a lab. A new review offers a guide to the wide variety of tests, or assays, that can be conducted to measure the fats, sugars, and other compounds in an insect's body—thereby revealing useful clues about how it stores and uses energy.
A new study suggests mosquitoes actually aren't all that good at finding holes in netting, doing so mostly by chance.
Researchers at the USDA-Agricultural Research Service find promising results using clay and silicate dusts to combat lone star ticks. They hope the dusts could be a useful tool against tick species that transmit deadly pathogens to livestock.
New research explores how pupae of certain butterfly species make a "twittering" noise—via a wiggling movement that triggers sound from tiny structures in the membranes between their abdominal segments.
A new study published in the Journal of Insect Science outlines a new technique that quickly, simply, and inexpensively marks bees to track their movement—and it's non-lethal, too. It could make for an valuable improvement for mark-and-recapture methods for these pollinators.
Insects have evolved a variety of mechanisms to try to overcome the effects of insecticides—including, in some cases, help from the bacteria and other microbes living in insects' guts. A growing number of studies indicate a link between symbiotic microbes and insecticide resistance in a diverse range of insects.
A wide variety of insects (such as mosquitoes, shown here) are raised in the laboratory. A new review of research on lab-reared insects shows that they evolve rapidly as they progress through generations raised in artificial environments.
A naturally occurring botanical compound found in anise, fennel, vanilla, and cranberries might be effective in deterring the larval stage of the lone star tick
