Twenty-seven sites reported this week. European corn borer (ECB)-E was caught at 4 sites and ECB-Z was also caught at 11 sites. Corn earworm was caught at 26 sites, with 24 sites showing counts high enough to warrant a 3, 4, 5, or 6-day spray schedule (refer to the table below). Fall armyworm (FAW) was caught at 6 sites, and Western bean cutworm (WBC) was caught at 4 sites.

Average sweet corn trap catches from 5.30.23– 9.5.23.

CEW eggs are usually very difficult to scout for but at sites with high pressure you can probably find eggs on the silks (see photos below).
