采用GLC/MS法对八种信息素进行鉴定。在frontalis Zimmerman中，除了先前报道的信息素外，雄虫还释放单萜酮pinocarvone和frontalin，雄虫和雌虫都释放萜类醇myrtenol。对于d.p onderosae Hopkins，除了已知的信息素外，雄性还释放了短尾素和3-甲基-2-环十己烯-1- 1 (MCH)，并从该物种对中收集了frontalin。生物测定结果表明，对黄花田鼠的外短尾草素和对花田鼠的桃金娘烯醇和马鞭草酮是多功能信息素，少量（雌性释放）具有协同吸引作用，而大量（雄性释放）具有抑制和/或引起“竞争”行为。对于后一种效应，雄性信息素被指定为反聚集-“竞争”信息素。对于D. ponderosae，我们的数据与之前的观点相矛盾，即该物种不释放抑制剂，依赖于宿主油树脂效应来阻止甲虫聚集。鉴定出的雄性信息素在雄性和成对放置的情况下均有释放，而雌性和成对放置的情况下均有释放，而雌性和成对放置的情况下均有释放。雌雄间和雌雄内的刺激和反应在信息素的释放中都起着重要的作用，这可能有助于回答有关树皮甲虫行为的某些问题，对利用这些信息素进行控制具有实际意义。
Eight pheromones were collected as volatiles from living Dendroctonus beetles, and identified by GLC/MS. With Dendroctonus frontalis Zimmerman, in addition to earlier reported pheromones, the monoterpene ketone pinocarvone, and frontalin, were released by males, and the terpene alcohol myrtenol was released by both males and females. With D. ponderosae Hopkins, besides the previously known pheromones, endo -brevicomin and 3-methyl-2-cyc1ohexen-1-one (MCH) were released by males, and frontalin was collected from pairs of this species. Bioassay indicated that exo -brevicomin with D. ponderosae , and myrtenol as well as verbenone with D. frontalis , are multifunctional pheromones, since a small quantity (released by females) was synergistically attractive, and a larger quantity (released by males) was repressive and/or evoked “rivalry” behavior. For this latter effect, the male pheromones were designated antiaggregative-“rivalry” pheromones. With D. ponderosae , our data contradict the previous belief that this species releases no inhibitor and depends upon host-oleoresin effects to stop beetle aggregation. The identified male pheromones were released with males placed together, as well as with pairs, and the pheromones of fmale D. frontalis (though not of female D. ponderosae ) were also released with females placed together, as well as with pairs. Both intrasex and intersex stimuli and response must be important in pheromone release, and may help answer certain questions about bark beetle behavior of practical significance in attempts to utilize these pheromones in control.
