Japanese Beetle - Reported Distribution

February 3, 2010

By the end of 2009 the Japanese beetle had been reported in 46 counties within the state of Iowa. The beetle is still primarily an eastern Iowa pest with a smattering of reports in the western half of the state. The updated distribution map is above.

Please keep us in mind next summer and send specimens or photographs from counties with no reports.
