A new study in the Annals of the Entomological Society of America examines how two ant species swim and concludes that bigger is indeed better when it comes to which of them swims fastest.
A 17-year study that monitored for resistance among cat fleas to the insecticide imidacloprid finds no evidence of decreased susceptibility. The study involved researchers in 10 countries, who tested more than 1,800 cat flea egg samples.
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.
In a new study at the University of Arizona, researchers used body-mounted cameras to evaluate the efficiency of two insect pest sampling techniques—a sweepnet and a vacuum—in a cotton field. The perspective offered new insights into how such methods can be evaluated and could help growers and integrated pest management professionals further fine-tune their sampling techniques.
To manage pest infestations in greenhouses, banker plants draw in different insect species that don’t feed on the main crop but do serve as hosts for predator insects that will also attack the pest on the main crop—a useful (and green) tool for integrated pest management.
Evaluation of the collapsible passive trap for mosquitoes shows performs as well as other commonly used traps but in a lighter, easier-to-carry design, making it an attractive option for mosquito monitoring in remote areas.
Researchers at USDA's Agricultural Research Service identified a chemical that enhances capture of the invasive brown marmorated stink bug (Halyomorpha halys) in pheromone traps
Citizen Scientists Collect 29,000 Mosquitoes in Germany and Help Detect Spreading Populations of Invasive Species
By Edward Ricciuti Armchair scientists nimble enough to catch insect lightning in a jar have helped the professionals map distribution of invasive mosquitoes in Germany—and they even detected three previously […]
By Edward Ricciuti Cornell University scientists are tuning up the entomological version of psych war tactics that, instead of killing insect pests outright, manipulate their behavior so they avoid crops […]
By Edward Ricciuti Males of an African butterfly, with the improbable nickname of “squinting bush brown,” are the Lepidopteran version of chick magnets—if their generation of caterpillars chills out while […]
By Edward Ricciuti Their common names—cigarette beetle and drugstore beetle—only hint at the amazingly eclectic and destructive diet of two related insects, which can wreak havoc on products stored in […]

By Ed Ricciuti Scientists have clocked many hours studying how females of various parasitoid flies home in on the calls of cicadas, grasshoppers, and other insects that are their hosts. […]
