WHEN WILL WESTERN BEAN CUTWORM FLIGHT BE OVER?

WBC 2014 Trap Totals
          
As predicted, we saw a slight decrease in the number of western bean cutworms caught in our monitoring network.  However, this was only seen in northwestern Ohio.  Instead, counties in northeastern Ohio had a dramatic increase in the number of adults, probably due to several weather systems coming across the lake.  Therefore, we are still in the window of egg laying, especially in corn that has just tasseled.  The total numbers this year have been surprising, given the low numbers last year.  We would be interested to hear of any larvae found feeding on ears, which can be observed for the next month or so, before larvae drop to the ground to overwinter.
