Corn Leaf Aphid: Kentucky Corn IPM

Corn Leaf Aphid


Description

Aphids are small, pear-shaped insects with soft bodies. They vary from blue-green to gray and have piercing-sucking mouthparts. They occur in sometimes very dense clusters on the plant. Most aphids in the cluster will be wingless, but some may have small, clear wings.

Damage

Corn becomes stunted or wilted, especially when plants are under drought stress. Aphids secrete a sugary substance known as "honeydew". Tassels of moderately to heavily infested plants may be quite sticky from accumulations of secretion. Aphids cause the greatest damage while feeding in the whorl.

Pest Activity
