Abstract

Last week, there were some reports of uncommon crop insect pests active in Iowa. Black cutworm larvae were reported in fields in Fremont and Ida counties. Since the cutting forecast map published in the May 11, 1998 ICM (page 69), there have been several additional moth flights across Iowa. This means that larvae of different sizes may be found during scouting. Once corn reaches growth stage V4 to V5, black cutworms can no longer cause significant damage to the field.
