DescriptionField tests on the efficacy of various scolytid bark beetle pheromones to attract Ipsperturbatus (Eichhoff) were conducted from 1977 through 1992 in stands of white spruce (Picea glauca (Moench) Voss) in interior Alaska. Several pheromones attracted high numbers of L. perturbatus and species of the predator Thanasimus to baited funnel traps. Test results also indicated that attacks by I. perturbatus may be deterred by certain semiochemicals.
