Abstract
Previous work by Kinghorn and Chapman (1959) has shown that in coastal British Columbia, the ambrosia beetle Trypodendron lineatum hibernates in the forest litter or duff at various distances within forest edges in the vicinity of brood logs. It was pointed out that further study was required to determine the characteristics of the optimum hibernation sites. It was mentioned that stand density, shade, aspect, slope, and the nature of the duff might be factors controlling the selection of the place of hibernation. The base of trees and the relatively deeper duff, characteristic of this situation, was reported to be the location of the larger populations of hibernating beetles although the level of population was found to vary greatly both from tree to tree and in depth within different forest edges.
