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 study on the durability of permethrin-treated clothing found that, after 16 cycles of wearing and washing the clothes, their repellent effect on ticks was indeed reduced, but it was still better than untreated clothing.
A study in Tennessee found ticks on about one in six cattle and at livestock monitoring locations in all regions of the state, highlighting a "hidden health threat" to the cattle industry.
Research in Singapore on katydid florivory could have applications in agriculture or even weed control.
In the Brazilian savanna, the larvae of a fruit-fly species exploits an ant-plant mutualism by trapping and preying on ants atop the plant's nectar deposits.
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 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.
The textbook approach to managing disease outbreaks focuses on pathogen, host, and environment but leaves out insect or arthropod vectors. For afflictions such as Zika, malaria, and Lyme, a report in the Annals of the Entomological Society of America proposes a new version of the classic 'epidemiologic triad' that better reflects the complexities of managing vector-borne diseases.
In the course of a study on mosquito movement, researchers discovered that local colonies of honey bees had foraged on a nontoxic sugar bait meant for the mosquitoes. The bait was dyed red to track mosquitoes that fed on it, but the dye also showed up in much of the bees' honey.
A survey of mosquitoes in Pennsylvania discovered 12 mosquitoes parasitized by larval mites. Water mites can reduce the survival and reproductive success of mosquitoes, and entomologists are investigating such parasitism to evaluate its potential as a method for biological control efforts.
A new collection in the July 2018 issue of the Annals of the Entomological Society of America offers growers a treasure trove of knowledge on pulse crop insect pests and management strategies.
A new study shows that harlequin bugs can adapt their pigmentation (or melanin levels) during their developmental stages based on outside temperatures. Such thermal melanism enhances the pest species' potential to invade new regions and environments.
A new study of genetic relationships in the grasshopper family Acrididae points to an origin in South America, not Africa, as previously thought. The findings about grasshopper evolution are reported in Insect Systematics and Diversity.
When a foreign parasitoid wasp was introduced to North America to control invasive pea aphids, it outcompeted most native wasps, except for one: Praon pequodorum. Its secret weapon: a resistance to pea aphids' natural defenses.
Ever wondered how one might feed 20 million fly larvae every week? Get a glimpse into the work of entomologists who fine-tune the diet for mass-reared screwworm flies at the Panama – United States Commission for the Eradication and Prevention of Screwworm.
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.
