2002 Light-trap Detection Survey for European Chafer, Rhizotrogus majalis (Raz.) (Coleoptera: Scarabeidae), a Turf and Grain Pest Recently Found In B.C., Canada

Eric H. LaGasa1, Patrik Hertzog2, and Denise Bowden2,

Executive Summary

European chafer is an exotic, root feeding beetle pest introduced into the Northeastern U.S. earlier this century, and recently found established in British Columbia, Canada. In the Northeast, it has caused serious impacts to turf, grain, and other crops and is now considered the worst pest of these commodities in some areas. A light-trap detection survey of areas in Northwestern Washington, closest to the known infested site in B.C., Canada, did not detect adult beetles.
