insect
 any larva of various moths (order Lepidoptera), including the pink bollworm of the family Gelechiidae (see gelechiid moth) and some Heliothis species. The larvae of the corn earworm (Heliothis zea), a member of the family Noctuidae, feed on the corn kernels near the tip of the ear. Because the larvae of this pest also burrow into tomatoes and cotton bolls, they are sometimes known as tomato fruitworms or cotton bollworms.

      Other plants attacked by the bollworm include peas, alfalfa, beans, soybeans, flax, peanuts, and other commercial crops. The pests can be controlled by natural parasites, early crop planting, trap crops, and insecticides.
