The cereal leaf beetle (CLB), Oulema melanopus, (Coleoptera, Chrysomelidae), is a pest of cereal grains, grass forage/seed crops, and other grass-host species in the Pacific Northwest (PNW) region (Oregon, Washington, Idaho, and Montana). In Washington, the CLB has caused yield losses of 25% in spring wheat (Pike and Gould 2002). Integrated pest management (IPM) for the CLB should begin with positive pest identification and field scouting to determine infestation rates. Cultural management methods and the use of biological control agents are possible ways to minimize the use of insecticides.
