Silk clipping insects like the corn rootworm beetle and the Japanese beetle feed on the green silks of corn plants and are most active during the plant's flowering stage. Damage from these insects can cause reduced kernel set and yield if significant silk clipping occurs during the critical pollination period. This publication has been prepared to help you evaluate corn fields during this period and to help you determine whether insecticide application is necessary to protect the corn silks from these beetle populations during pollination.
