Extract

Scolytus tsugae (Swaine) is a bark beetle that occurs throughout the Pacific Coast and Rocky Mountain Region and is common in the interior of British Columbia. Although Bedard (1938) reported that it had killed small areas of Douglas fir (Pseudotsuga menziesii (Mirb.) Franco) reproduction, it is of minor economic importance and usually confines its attack to tops, limbs, and logging slash. A knowledge of the life-history and habits of this insect is desirable for an understanding of the effects of interspecific competition on the development of the Douglas-fir beetle, Dendroctonus pseudotsugae Hopk., with which it is often associated in Douglas fir.
