Twenty-four sites reported this week. European corn borer (ECB)- E was caught at five sites and ECB-Z was caught at five sites. The hybrid ECB was caught at two of the six sites trapping for it: Bellona (3) and Penn Yan (2). Twenty-two sites reported corn earworm (CEW) catches this week with twenty-one sites high enough to be on a 3, 4, 5, or 6 day spray schedule (see table at bottom of post). Fall armyworm (FAW) was caught at thirteen sites and Western bean cutworm (WBC) was caught at four sites.
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). While CEW is most attracted to green silk stage fields for egg-laying, as the number of attractive fields decreases, fields with drying silk may become more attractive, prolonging the period when sprays are needed. CEW will also infest peppers and tomatoes when populations are high.
