Responses of Ips pini (Say), Pityogenes knechteli Swaine and associated beetles (Coleoptera) to host monoterpenes in stands of lodgepole pine
Journal of Entomological Science 38 (4), 602-611
Abstract: We conducted seven experiments in stands of mature lodgepole pine in southern British Columbia to elucidate the role of host volatiles in the semiochernical ecology of the pine engraver, lps pini (Say) (Coleoptera: Scolytidae), with particular reference to the behavioral responses of predators and competing species of hark beetles. Our results demonstrate that the attraction of lps pini and the bark beetle predators Lasconotus complex Leconte (Colydiidae), Thanasimus undatulus (Say) (Cleridae) and a Corticeus sp. (Tenebrionidae) were increased by 3-carene. In contrast, attraction of the bark beetle Pityogenes knechteli Swaine (Scolytidae) to ipsdienol was interrupted by 3-carene. and alpha-pinene. Attraction of L. complex to ipsdienol was increased by gamma-terpinene, a compound attractive to the mountain pine beetle, Dendroctonus ponderosae Hopkins (Scolytidae). Terpinolene interrupted the attraction of l. pini to ipsdienol.
