Cereal Leaf Beetle: Identification, Control, and California Quarantine Alert

Lynn Royce and, Ben Simko (August, 2000)

Summary

The cereal leaf beetle (CLB), a serious pest of cereals and grasses, was found in Oregon in 1999. As a result, California has imposed a quarantine on certain agricultural products from Oregon. CLB can cause considerable damage to small-grain crops. Yield losses of up to 23 percent in winter wheat and 75 percent in barley and oats have been reported.
