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.

Invasive Insects: The Top 4 “Most Wanted” List

The list of invasive insects in the United States is a long one, but one entomologist offers his list of the top four "most wanted"—plus a note about how entomologists are working to better manage the challenge of invasive insect species.

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.
