Western Bean Cutworm Monitoring Update for Week Ending August 25, 2017

This is the final week for WBCW trap monitoring in Ohio as very few numbers are being reported in trap counts across the state. We would like to thank everyone for their participation including land owners and farm cooperators who allowed us to place traps in their fields and monitor WBCW this season. For week ending August 25th, a total of 61 traps were monitored in 19 counties. Overall, 21 WBCW adults were captured, with 12 counties reporting a “zero” for their trap count. The state average also decreased from 2 WBCW (week ending August 18) to less than 1 WBCW (week ending August 25). Next week we will provide an overall summary of WBCW trap monitoring for 2017.

Amy Raudenbush, Kelley Tilmon, Andy Michel, Mark Badertscher, Lee Beers, JD Bethel, Bruce Clevenger, Sam Custer, Thomas Dehaas, Allen Gahler, Jason Hartschuh, Cecelia Lokai-Minnich, David Marrison, Les Ober, Eric Richer, Garth Ruff, John Schoenhals, Jeff Stachler, Alan Sundermeier, Chris Zoller participated in monitoring Western bean cutworm moths.
