Western bean cutworm (WBC) adult moth trapping is winding down across the state as very few adults are being captured in the bucket traps. For week ending August 18, 11 counties reported zeros and the statewide average was 1.2 moths per trap (76 total captured) (Figure 1). This data was collected from 20 counties that monitored 61 traps. The previous week trap average was 3.0 moths per trap (221 total captured). Next week will be our final WBC adult trap update.
