The responses ofIps 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 β-phellandrene, demonstrating that β-phellandrene is a kairomone for this species.Lasconotus complex (Colydiidae) and aCorticeus sp. (Tenebrionidae) were attracted to both ipsdienol and β-phellandrene. TheCorticeus sp. exhibited a synergistic response to the combination of ipsdienol and β-phellandrene; the responses of the other two species to the combination were additive. The predators,Thanasimus undatulus, Enoclerus sphegeus, andE. lecontei (Cleridae), were attracted to ipsdienol-baited traps, whileMonochamus clamator (Cerambycidae) andDendroctonus ponderosae (Scolytidae) were attracted to β-phellandrene. Attraction of all eight species increased with increasing release rates of ipsdienol and/or β-phellandrene.
本研究在不列颠哥伦比亚省南部和中部的黑云杉林中,利用信息素(ipsdienol)和多种单萜化合物对松墨天牛(Scolytidae)的多个漏斗陷阱的反应进行了测定。ipsdienol 和 β-蒎烯均能吸引松墨天牛,这表明 β-蒎烯是该物种的信息素。Lasconotus 复合种(Colydiidae)和一种 Corticeus sp.(鞘翅目)对 ipsdienol 和 β-蒎烯均有趋性。Corticeus sp. 对 ipsdienol 和 β-蒎烯的组合表现出增效反应;其他两种物种对该组合的反应为相加性。捕食性昆虫,Thanasimus undatulus、Enoclerus sphegeus 和 E. lecontei(Cleridae)对 ipsdienol 诱饵陷阱有趋性,而 Monochamus clamator(鞘翅目)和 Dendroctonus ponderosae(鞘翅目)对 β-蒎烯有趋性。随着 ipsdienol 和/或 β-蒎烯释放率的增加,所有 8 种物种的趋性均增加。
