Fruit DNA in Invasive Flies’ Guts Could Help Track Their Dispersal

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.

Study Shines a (Fluorescent) Light on Invasive Fruit Fly Trapping

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.

Two Artificial Sweeteners Kill Fruit Flies

Continuing their research into potential ingredients for human-safe pesticides, Drexel University researchers recently found an artificial sweetener that, while harmless for male fruit flies, proved particularly lethal for females. Their […]

Discovery May Lead to “Anti-Viagra” for Insects

Kansas State University entomologists have helped identify a neuropeptide named natalisin that regulates the sexual activity and reproductive ability of insects. Using a genetic tool called RNA interference, or RNAi, […]
