通过对雌虫的曝气和对挥发物在Porapak-Q上的吸附，分离出4种斑纹夜蛾的主要性信息素组分。结果表明：(Z)-14-甲基-8-十六烯醛是黑曲霉和多变红曲霉的主要成分，(E)-14-甲基-8-十六烯醛是光滑曲霉的主要成分。(Z)-和(E)-14-甲基-8-十六烯醛均存在于石斑潜蝇体内，其比例为92Z：8E。在实验室生物检测中，雄性甲虫对醛表现出唤醒和交配反应，并能区分几何异构体。计算每个物种的醛的日产量，并检测其他活性成分。这些曝气-吸收研究与早期对浸泡甲虫的研究形成了鲜明对比，在这些研究中，没有检测到醛。文中还介绍了曝气-吸收系统采集性信息素的效果。吸收剂(Porapak-Q)有效地收集了活性信息素；系统的其他部分只剩下少量的活性。
A major sex pheromone component of each of four Trogoderma species was isolated by aeration of the female beetles and absorption of the volatiles on Porapak-Q. (Z)-14-Methyl-8-hexadecenal was identified as the major component in T. inclusum and T. variabile, and (E)-14-methyl-8-hexadecenal was identified in T. glabrum. Both (Z)- and (E)-14-methyl-8-hexadecenal were found in T. granarium (Khapra beetle), in the ratio 92Z: 8E. In laboratory bioassays, male beetles exhibited arousal and mating responses to the aldehydes, and could discriminate between the geometric isomers. The daily production of the aldehyde was calculated for each species, and other active components were detected. These aeration-absorption studies contrast with earlier studies on macerated beetles, in which the aldehyde was not detected. The efficacy of the aeration-absorption system for collection of the sex pheromones is also described. The absorbent (Porapak-Q) efficiently collected the active pheromone; only minor amounts of activity were left in the other parts of the system.
