Twenty-seven sites reporting this week. European corn borer (ECB)-E  was trapped at four sites and ECB-Z was trapped at one site, with the Hurley site having a count of 73. Corn earworm (CEW) was trapped at 21 sites, with 20 sites high enough to be on a 3, 4, 5 or 6 day spray schedule (see chart below). CEW have come down this week as compared to last week, but we still caught over 200 moths at one location. Fall armyworm (FAW) was caught at six sites and Western bean cutworm (WBC) was caught at only one of the reporting sites.
