Description

In Iowa, ECB normally goes through two generations per year. Both generations are destructive to corn during the insect's larval stage. Scouting for first generation ECB larvae begins when corn has reached an extended leaf height of seventeen inches. Infected plants are characterized by small shotholes in the leaves caused by larval fee4ing. A trained eye can spot shotholes very easily. Economic thresholds are computed after pulling whorls and counting live larvae.
