Integrated Crop Management News

Since my June 30 ICM News article about Japanese beetle activity in Iowa, there have been many reports of adults feeding in corn and soybean. Adult Japanese beetles are metallic with white tufts along each side of the body. Several extension field agronomists have also reported seeing beetles in new areas this summer. Japanese beetles have a wide host range, feeding on more than 300 different plant species. With so much corn and soybean in Iowa, it's probably no surprise they are expanding range here.
