Abstract
The cowpea curculio, Chalcodermus aenus Boheman, is the key pest of cowpeas in the Southeastern USA. There is limited published information available on the life history, trapping, and control of this serious pest. Current commercial control tactics are almost entirely foliar sprays of insecticides that target the above-ground adult life phase of the curculio which are failing to provide adequate control. This research evaluated the use of insecticides and biological control agents, applied post-harvest, targeted at the soil phase of this pest. Additional research focused on potential diapause of overwintering females. This research is the first to document diapause in cowpea curculio and to publish field efficacy data on biological and chemical treatment options targeting the control of the curculio in the soil phase in Georgia.
