Helicoverpa zea, commonly known as the corn earworm, is a species of moth belonging to the family Noctuidae. It is primarily found in North America and is known for its larvae, which are significant agricultural pests. These caterpillars feed on a variety of crops, including corn, cotton, and tomatoes, causing substantial damage to fruit and vegetable production. The adult moth has a wingspan of about 3 to 4 centimeters and is characterized by its brownish-green coloration with distinctive markings. Helicoverpa zea undergoes complete metamorphosis, transitioning from egg to larva, pupa, and finally to adult moth. Effective pest management strategies are essential to control its population and minimize crop losses.
