Abstract

A survey was conducted to study the incidence of attack by the white pine weevil, Pissodes strobi (Peck) on white spruce, Picea glauca (Moench) Voss., in the Prince George Region of British Columbia, in relation to biogeoclimatic subzone, site quality class and plantation age. The average percentage attack on the spruce component was 3.2% (range 0 to 26.6%). A general trend of increasing attack with increasing biogeoclimatic subzone moisture was found. No correlation was found between percentage attack and site quality or age. The implications of this survey for the Prince George Region are discussed.
