European corn borer numbers remain low this week, while corn ear worm (CEW) catches have increased enough to be driving the spray schedule at most locations.  For recommended spray intervals based on trap catches see the chart 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.  Fall armyworm catches remain low and spotty, and western bean cutworm are being caught in low numbers at less than half the locations reporting this week.

Trap catches for the week of 8/28-9/4/12
