Current Susceptibilities of Bollworms from the Mississippi Delta to a Diamide Insecticide

Bollworm larvae were collected from wild hosts and corn from locations in MS, AR, and LA during 2016-2019. Larvae were reared to adults and the F1 generation was tested for tolerance to a diamide insecticide (Prevathon) in diet-incorporated bioassays. Differences among populations will be compared and populations will also be compared to earlier studies.
