Old World Bollworm (Helicoverpa armigera) found in United States!

Todd Gilligan, LepIntercept, USDA APHIS ITP,

On June 17, 2015, one male Helicoverpa armigera (old world bollworm) was collected in a Cooperative Agricultural Pest Survey (CAPS) pheromone trap in a field in Bradenton, Florida, USA. This moth is a serious agricultural pest globally, and this is the first detection in the U.S. outside of port interceptions. The caterpillars feed on a wide variety of field crops, the adults can fly long distances, and populations have repeatedly evolved resistance to many insecticides.
