Ipsenol was identified from the frass of male, but not female,Ips latidens from British Columbia, feeding in phloem tissue of lodgepole pine,Pinus contorta var.latifolia. The responses ofJ. latidens to sources of ips-enol andcis-verbenol were determined with multiple-funnel traps in stands of lodgepole pine in British Columbia. Ipsenol attracted both male and femaleI. latidens, verifying that it is a pheromone for this species. MaleI. latidens showed a slight preference for (S)-(-)-ipsenol.cis-Verbenol was not produced by beetles of either sex and, in contrast to an earlier report, both enantiomers inhibited attraction to ipsenol-baited traps. The predators,Enoclerus sphegeus andThanasimus undatulus (Cleridae), were attracted to traps baited withcis-verbenol and ipsenol.
从加拿大不列颠哥伦比亚省吸食花旗松韧皮部组织的雄性、而非雌性的星天牛 I. latidens 的粪便中鉴定出伊普西隆。利用不列颠哥伦比亚省花旗松林中的多漏斗诱捕器测定了 J. latidens 对伊普西隆和顺式马鞭草烯醇源的反应。伊普西隆吸引了雄性和雌性的 I. latidens，这验证了它是该物种的信息素。雄性 I. latidens 对 (S)-(-)-伊普西隆表现出轻微的偏好。顺式马鞭草烯醇不是雌雄两性甲虫产生的，与早先的一份报告相反，两种对映体都抑制了对伊普西隆诱饵陷阱的吸引力。捕食者，Enoclerus sphegeus 和 Thanasimus undatulus（ cleridae），被顺式马鞭草烯醇和伊普西隆诱饵的诱捕器吸引。
