Damage - Fruitworms, primarily the tomato fruitworm, feed on tomato leaves and fruit. Distorted leaves often result from feeding upon the tips of the leaves in the developing bud. Both species may also bore in stalks or midribs. History - Fruitworms overwinter as pupae in the top 4 cm of soil. Tomato fruitworm adults emerge from early May to early June.
Females generally emerge earlier than males.
Tobacco budworm adults emerge in North Carolina from late April to mid-May. Eggs are deposited on the leaves or buds of tomato plants. After hatching, larvae may first feed on leaves and then move to buds or fruit. Tomato fruitworm larvae have 5 to 6 instars with the development period varying from 21 to 25 days. Tobacco budworm development is similar.
