Meet the Mosquito With a Big Appetite—for Other Mosquitoes

The mosquito species Toxorhynchites rutilus is harmless to humans but is a voracious predator of other mosquitoes. Researchers in Houston, Texas, are hoping the "mosquito assassin" could be put into action as a tool for controlling mosquitoes that carry human pathogens—if they can find an efficient way to raise the predator mosquitoes in the lab.

Trichopria anastrephae

New Study Aims to Protect Parasitoids of Spotted-Wing Drosophila

Use of an insecticide can be counterproductive if it also harms natural enemies of a target pest. A new study puts several insecticides currently in use to manage spotted-wing drosophila to the test to see how they do or don't affect parasitoids of the invasive fruit fly.

To Boost IPM Adoption, Treat It as a Complex Social System

Pest management is more than just matching pests with control methods. A tangled web of societal influences also play a role in growers' decisions and their uptake of integrated pest management, and researchers say the science of "social ecological systems" can inform efforts to increase IPM adoption.

Pollen Sleuths: Tracking Pesticides in Honey Bee Pollen to Their Source Plant

When pesticides show up in the pollen that honey bees collect, can the source plant be pinpointed? A new study is the first to successfully combine chemical analysis of pollen and the keen eye of a palynologist—an expert in identifying pollen microscopically—to track pesticide in bee-collected pollen to a source plant genus.

Stink Bugs Stay Out: Study Measures Gaps Needed for Invasion

If a structure has a gap or entrance large enough for brown marmorated stink bugs to fit through, they will find it. But a new study shows that slits less than 3 millimeters wide and holes less than 7 millimeters wide should successfully exclude the vast majority of the bugs. A related study examines how overwintering stink bugs react to corpses of their fellow bugs remaining from previous winters.

Pacific cicada killer - Sphecius convallis

When Cicada-Killer Wasps Become Cicada-Stealer Wasps

Hunting cicadas and lugging them back to a nest is hard work for a cicada-killer wasp. But sometimes all that hard work goes to waste, when a fellow wasp swoops in and lays her egg on the other wasp's prey. And that's if the cicada isn't stolen by a bird first.
