The diamondback moth is a common pests of Brassica crops in south Georgia. The environment and cropping systems in this area allow for year-round reproduction of diamondback moth on commercial acreage of favorable host crops. These crops have very low tolerances for insect damage, which has resulted in a heavy reliance on insecticidal control and severe selection pressure for insecticide resistance. Resistance and/or control failures have been documented to multiple classes of insecticides, including several recently registered products. Factors which likely contributed to this problem will be presented. Current and potential actions addressing mitigation of these problems will also be presented.
