CEREAL LEAF BEETLE: Kentucky Wheat IPM

Cereal Leaf Beetle


Description

Overwintering adult cereal leaf beetles can be found in Kentucky small grain fields from early April until mid-May. Their eggs are laid from mid-April until late May, and larvae occur from late April through mid-June. Cereal leaf beetle adults are shiny black beetles with red legs and thorax, approximately 1/2 inch long.

Damage

The adults and larva tear out long narrow strips of tissue between the leaf veins. This feeding pattern leaves long whitish scars on the leaves.
