Host: flue-cured tobacco (Nicotiana tabacum (flue-cured type)
Description: Tobacco budworm and corn earworm [Heliothis virescent (Fabricius), Helicoverpa zea (Boddie)]: Both species attack tobacco, but the budworm is predominant. Larvae of both species are closely related, similar in appearance, and cannot be distinguished with the naked eye. When fully developed, larvae can range from pale greenish-yellow to red-brown to nearly black. Most have pale striped running lengthwise on the body, and small dark spots may be visible on each body segment. All have five pairs of fleshly prolegs in addition to three pairs of jointed legs near the head. The primary distinguishing feature of these pests is their habit of feeding in the bud. As this damage expands with the leaf, large regular holes are produced. Both species may also top plants, tunnel into stalks or midribs of leaves, or feed on seed pods. After topping, they may produce more irregular holes in expanded leaves.
