Abstract
Pine oil, derived from pulp mill by-products, and oleic acid significantly delayed and reduced the attack by ambrosia beetles Trypodendron lineatum (Oliv.) and Gnathotrichus spp. on Douglas-fir logs. Pine oil also appeared to interfere with the attack by bark beetles. The possibility of combining the use of repellents with a pheromone-based diversion scheme is suggested as an effective protection strategy.Keywords
