The tobacco budworm is one of the most destructive pests of the tobacco. Eggs, laid by the adult moth on the tobacco leaves, hatch and eventually develop into 1 1/2-inch long larvae when full grown. The larvae are light to dark green and have several longitudinal pale stripes. They may chew small holes in the leaves before they reach the buds. Larvae then damage the bud or growing tip of the plant. They may appear any time during the growing season. The leaves that expand from the buds are often ragged and distorted. Because of their protected location on the plant, budworms are difficult to control. The corn earworm, Heliothis zea (Boddie), also attacks burley and is closely related to the budworm in appearance and feeding habits.
