Samples of tobacco budworm (Heliothis virescens; TBW) and cotton bollworm (Helicoverpa zea; CBW) populations were collected from cotton fields throughout the south/southwestern corner of Georgia. Larvae from those field-collected samples were assayed for susceptibility to a variety of insecticides using a treated diet bioassay. Several TBW strains demonstrated significant tolerance to MVP II^® as compared to the most susceptible field strain and an insecticide-susceptible lab strain (OPS). MVP II^® was less effective against CBW larvae. Several TBW strains were slightly tolerant (4-8-fold) to cypermethrin as compared to the most susceptible field strain. The activities of Fipronil, Pirate^®, and Spinosad were good against all strains tested. In general, the 96 h activity spectrum for the compounds tested were: Spinosad > Pirate^® > Fipronil > Cypermethrin > MVP II^®.
