Researchers in China say a protein bait derived from leftover brewer's yeast attracted more spotted-wing drosophila flies than existing attractants in a lab test.
Subterranean termite colonies can be as large as 1 million individuals with a foraging territory and underground galleries stretching up to 100 meters long. How does an entomologist study something that large? Here's a behind-the-scenes look at how researchers at the University of Florida have raised entire termite colonies from scratch and devised experimental setups that mimic large foraging and nesting areas while still fitting inside a lab.
Boric acid dust is a common tool in urban pest management, but a new study shows external exposure is minimally effective against bed bugs. When bed bugs ingest boric acid, though, few survive.
Honey bees detect and remove brood afflicted with parasites or pathogens. A new study shows that part of this "hygienic behavior" relies on chemical signals emitted by unhealthy brood, and brood coming from colonies bred to be more hygienic are more effective in signaling for their own removal.
Research in Singapore on katydid florivory could have applications in agriculture or even weed control.
A new termite-control method currently in development looks to combine the advantages of a liquid insecticide application with the comprehensive impact of existing solid termite bait systems.
A new study shows that long-lasting insecticide netting could have promising applications in stored-product facilities to protect foods like wheat, corn, and soybeans from insect pests.
A new study on insect-based chicken feed, made from black soldier fly larvae, finds an improved cost-benefit ratio and return on investment compared to soybean- or fish-based chicken feed.
Existing baits for yellowjackets require fresh meat as an attractant, but a new study finds that hydrogel makes an adequate substitute, absorbing insecticide and giving a tactile resemblance to meat to effectively bait yellowjackets in the same manner.
A new study finds spotted-wing drosophila prefer red, glue-covered monitoring traps made of plastic rectangles or spheres compared to the most commonly used clear deli-cup traps. The findings will advance the pursuit of more efficient and effective monitoring techniques for the pest.
A recent study at North Carolina State University shows that DNA analysis of spotted-wing drosophila (Drosophila suzukii) flies can detect whether they fed on strawberries as much as seven days prior. Researchers hope the proof of concept will lead to more accurate analysis of the invasive pest's dispersal in the field.
To estimate the catch rate of traps for invasive spotted-wing drosophila fruit flies in tart cherry orchards, researchers at Michigan State University first marked thousands of flies with fluorescent dust and released them. Then they counted the recaptured flies under ultraviolet light.
A study in Brazil finds that a common fungicide can impair the oxygen consumption and silk production of silkworms if applied to their preferred food source, mulberry leaves.
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.
In a study on three commonly cited natural spider repellents, both chestnut and peppermint oil showed apparent repellent effects on two species of spider but not on a third. Meanwhile, lemon oil did not have a significant effect on any of the three species included in the study.
A study by entomologists in Italy found that the abundance of bark- and wood-boring beetles outside their native range but still within the same country is correlated with levels of trade at nearby sea ports, suggesting domestic sea transportation plays a role in insects' intra-country range expansion.
