ß-Phellandrene: Kairomone for Pine Engraver, Ips pini (Say) (Coleoptera: Scolytidae)

Abstract

The responses of Ips pini (Scolytidae) to multiple-funnel traps baited with the pheromone, ipsdienol, and various monoterpenes were determined in stands of lodgepole pine in southern and central British Columbia. Ips pini was attracted to both ipsdienol and ß-phellandrene, demonstrating that ß-phellandrene is a kairomone for this species. Lasconotus complex (Colydiidae) and a Corticeus sp. (Tenebrionidae) were attracted to both ipsdienol and ß-phellandrene. The Corticeus sp. exhibited a synergistic response to the combination of ipsdienol and ß-phellandrene; the responses of the other two species to the combination were additive. The predators, Thanasimus undatulus, Enoclerus sphegeus, and E. lecontei (Cleridae), were attracted to ips-dienol-baited traps, while Monochamus clamator (Cerambycidae) and Dendroctonus ponderosae (Scolytidae) were attracted to ß-phellandrene. Attraction of all eight species increased with increasing release rates of ips-dienol and/or ß-phellandrene.
