When it feeds on corn, as in the Northeast, it is the corn earworm; in the South when it feeds on cotton it is the cotton bollworm; and when it feeds on tomatoes it Is the tomato fruitworm. Its damage is severe in southern states because it survives the winter and attacks crops throughout the growing season. The adults migrate northward annually, arriving in the northeastern United States and Canada from mid-July to late August depending on weather and wind patterns. There are one or two generations a year in the northeastern states depending on the time of arrival and temperature in late summer and early fall. The corn earworm is a general feeder, attacking many cultivated crops and weeds. It causes serious injury to tomatoes, tobacco, cotton, and soybeans, as well as corn.
