Western Bean Cutworm Numbers Remain Low Across Ohio

We are now in the second week of monitoring for Western bean cutworm (WBC) in Ohio. Similar to last week, WBC adult numbers remain low in all monitoring counties. Trap counts for the week of June 29 – July 5 resulted in a total of 56 WBC adults (0.67 average moths per trap) (Figure 1). Overall, 26 counties monitored 84 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.
