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.

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.
