Helicoverpa zea and Heliothis virescens are pests on a variety of crops including cotton, soybean, lettuce, tomato, tobacco, and other vegetable and ornamental crops. The unexpected and sometimes sudden arrival of migrant moths in the U.S. cropping systems make the control efforts ineffective. Therefore, source reduction of pests is crucial for the success of pest management strategies.
