Multiple-funnel traps baited with exo-brevicomin and a mixture of cis-and transverbenol were used to test the relative attractiveness #If myrcene and (-)-a-pinene to the mountain pine beetle, Dendroctonus ponderosae Hopkins, in a stand of western white pine, Pinus monticola Doug].Traps baited with myrcene caught significantly more D. ponderosae than traps baited with (-)-a-pinene, irrespective of the presence of exobrevicomin.exo-Brevicomin was attractive to Thanasimus undatulus (Say) (Coleoptera: Cleridae) whereas Trypodendron lineatum (Olivier) (Coleoptera: Scolytidae) was attracted to (-)-a-pinene.Our results support the use of myrcene in commercial trap lures and tree baits for D. ponderos,ze in stands of western white pine in British Columbia.
