Adult Japanese beetles are emerging in central Illinois. Be watchful for these insects on linden, willow, birch, crabapple, rose, and other trees and shrubs. They will be feeding on the upper surface of the top leaves of the plant. Because these insects tend to feed where previous feeding has occurred, early application can greatly reduce feeding damage later. Carbaryl (Sevin) and cyfluthrin (Tempo), as well as other synthetic pyrethroids, should provide control for about 2 weeks. Heavy numbers of beetles are likely to be present through mid-August.
