Susceptibilities of Bollworm and Tobacco Budworm to Commonly Used Insecticides

Laboratory assays were used to assess current susceptibilities of tobacco budworm and bollworm to pyrethroid and diamide insecticides.  Populations were collected and the F1-F2 generations were examined for tolerances to selected insecticides through diet-incorporated and topical applications directly to the larvae.  Results show that susceptibilities of bollworm and tobacco budworm are similar to a diamide insecticide.
