Western bean cutworm (WBC) adult moth catches decreased across monitoring counties in Ohio. For week ending August 4, 23 counties monitored 73 traps (Figure 1). Overall, there was a statewide average of 5.6 moths (406 total captured). This is a decrease from an average of 15 moths per trap (1090 total captured) the previous week. Two consecutive weeks of WBC adult captures indicate that Ohio is past peak flight for WBC adults.
