Fall Armyworm Update

This past week was our 21st week of monitoring moth pests in Ohio. We monitored from September 8th to September 14th. The reminder of monitoring this year will focus on FAW moths.

Days remained warm and dry across Ohio over the past week – but nights are continuing to cool off. Fall is approaching and harvest is around the corner. Over the past week we had 10 counties participate in monitoring with the statewide average continuing to decrease from 6.6 moths per trap to 3.6 moths per trap. The highest moth average over the past week is down to 10.5 moths in Morgan Co, followed by 9.0 in Sandusky (Figure 1). All other counties reported low moth counts.
