The flight of black cutworm into central Iowa continues. A light trap in Ames caught substantial numbers of moths on consecutive nights during May 17-20. These trap catches suggest that egg laying may still be occurring in corn in central Iowa, and perhaps other areas of the state as well. Therefore, all corn should be scouted for black cutworm injury when the plants emerge. This recommendation includes corn that emerges in late May and early June.
