Western Bean Cutworm Update: Past Peak Adult Flight

Western bean cutworm adult

The majority of counties in Ohio are now past Western bean cutworm (WBC) adult moth peak flight. Trapping efforts last week (August 5 – August 11) resulted in 195 WBC adults across the state (a decrease from 824) and a statewide average of 2.5 moths/trap (a decrease from 10.4 average) (Figure 1). Currently the only location with scouting levels is Lucas County.
