Helicoverpa zea, commonly known as the corn earworm or cotton bollworm, is a major agricultural pest that attacks a wide variety of crops including corn, cotton, soybeans, and tomatoes. Research on Helicoverpa zea focuses on understanding its biology, behavior, and ecology in order to develop effective pest management strategies. This includes studying its life cycle, feeding habits, mating behavior, and interactions with natural enemies. Researchers also investigate the development of resistant crop varieties, biological control methods, and the use of insecticides to manage populations of Helicoverpa zea and minimize crop damage.
