The bollworm (Helicoverpa zea) and the tobacco budworm (Heliothis virescens) are two of the more economically important pests of cotton in the United States, and without proper control methods, populations of these pest insects could reach damaging levels and severely reduce crop yields. Because the bollworm and tobacco budworm have developed resistance to many of the insecticides used for their control, it is critical that research efforts and agricultural practices be devoted to the preservation of those insecticides that are still effective and to the development of new replacement compounds and technologies. Programs to monitor insecticide susceptibilities in field-collected populations of bollworm and tobacco budworm are critical to the development of effective management strategies. Samples of bollworm and tobacco budworm (TBW) populations were collected from cotton, tobacco and corn fields throughout Georgia during the summer of 2005. Larvae from those field-collected samples were assayed for susceptibility to a variety of insecticides using a treated-diet bioassay. Results were compared to baseline data collected between 1995-1999 and 2003-2004.
