Extract

Graham (1968) demonstrated that logs became attractive to ambrosia beetles after the sapwood was subjected to anaerobic conditions. Pursuing this lead, Cade et al. (1970) and Moeck (1970a, 1970b, 1971) extracted, analyzed, and bioassayed anaerobic products from western hemlock and Douglas-fir trees and ascertained that ethanol was the principal “primary attractant” to the ambrosia beetles, Gnathotrichus sulcatus (LeConte) and Trypodendron lineatum (Olivier), respectively. The demonstration that ethanol enhanced the response of the Douglas-fir beetle, Dendroctonus pseudotsugae Hopkins, to its aggregation pheromones frontalin and seudenol (Pitrnan et al. 1975) suggested that ethanol could also be involved in the primary attraction of or host recognition by bark beetles. We report that the mountain pine beetle, Dendroctonus ponderosae Hopkins, is arrested to ethanol in a laboratorv olfactometer.
