Which insect, identified as Helicoverpa zea, is a pest for which crop?

Helicoverpa zea, commonly referred to as the corn earworm, is particularly known for its damaging effects on cotton crops. This pest is notorious for feeding on the reproductive structures of the plant, which can significantly reduce yield and quality. The larvae of Helicoverpa zea burrow into various parts of the cotton plant, including the buds and developing bolls, leading to the destruction of the cotton fibers. While it can also affect other crops such as corn and soybeans, its primary economic impact is observed in cotton production, making it a major concern for cotton farmers.
