Distribution of economically important, wood-infesting anobiid beetles in the Pacific Northwest

Structure-infesting anobiid beetles were surveyed in Washington State homes and outbuildings during 1987-91. Hemicoelus (= Hadrobregmus ) gibbicollis (LeConte) was found in virtually all of the 90 structures inspected and is the predominant species infesting building timbers. This anobiid is known primarily from coastal areas of western North America. Hadrobregmus quadrulus (LeConte) was discovered in 5.5% of infested structures while Xestobium affine LeConte and Priobium punctatum (LeConte) were found in only 2% of infested buildings. The curculionid, Rhyncolus brunneus Mannerheim, also infests structural timbers and was present in 8% of buildings examined in this study.
