Western Bean Cutworm Update August 9th

Three Western Bean Cutworm Feeding on a single ear -2011

By Greg LaBarge, Fulton County

WBCW moth flights dropped off to very low numbers last week as we expected. The larvae stages might be seen in areas fields. The picture to the left was taken near Delta with numerous larvae on single ears in some cases. As you can see they are different sizes even on the same ear. The hybrid was a non-gmo in a test plot area where we identified egg laying back on July 21st.

The larvae can be found feeding on the end of the ear but often borer through the husk  leaving a hole in the

husk. See the picture below and to the left from 2010.

If you see feeding activity anywhere in northwest Ohio we would be interested in knowing. Give me a call 419-337-9210 or labarge.1@osu.edu.
