Western Bean Cutworm Monitoring in Ohio

Monitoring for the Western bean cutworm (WBC) began the week of June 22nd across Ohio. Currently, WBC adult numbers are low in all monitoring counties. Trap counts for the week of June 22 – 28 resulted in a total of 17 WBC adults (0.23 average moths per trap) (Figure 1). Overall, 24 counties monitored 74 traps across Ohio. No counties reported capturing more than 1 moth / day over the 7-day monitoring period; therefore, all counties currently remain below the recommended levels that indicate scouting for egg masses should begin.
