Abstract
MaleI. paraconfusus confined to artificial entrance tunnels in white fir logs produced the pheromone compounds ipsenol and ipsdienol in their hindguts. The hindguts were attractive to females in a laboratory olfactometer and the male infested logs were attractive in field bioassay. The amount of pheromones produced and the amount of feeding and boring activity is much less in white fir than in ponderosa pine. There were no pheromones detected in the hindguts of recently emerged, unfed males.
