Abstract

The corn earworm has surprised a number of people this summer because populations of the insect are fairly abundant in whorl-stage cornfields in central and western Iowa. Reports of 30-50 percent of the plants being infested are common from those field scouts that have recognized the insect and its injury. Many light green larvae are being found, resulting in some misidentification. The corn earworm typically has a freckled orange head (although sometimes it is green), alternating stripes of darker and lighter colors, and dark setae (hairs), with four pairs of prolegs in the middle of the body.
