Moth trap updates for Ohio are reported below. All monitored pests remained below an average of 10 moths per county for the week of June 6 – 12. This will be our last update for black cutworm and true armyworm. We will continue to report on European corn borer catches and begin reporting on corn earworms starting next week. Western bean cutworm reporting will begin the week of June 27th.
