Hexanoic acid, 1-octanol, 1,8-octanediol, octyl hexanoate, 1,8-octanediol monohexanoate, and 1,8-octanediol dihexanoate were identified in headspace volatiles collected from the crushed abdomen of a female click beetle of the species Parallelostethus attenuatus (Say) (Elaterinae, tribe Elaterini). In field trials carried out in Illinois, South Carolina, North Carolina, and Virginia, adult male beetles were strongly attracted to 1,8-octanediol dihexanoate alone. Blends of the dihexanoate with one or more of the other compounds proved to be less attractive than the dihexanoate alone, suggesting that the pheromone of this species may consist of a single compound. The symmetrical diester structure of the pheromone is a novel natural product and appears to be structurally unique among insect pheromones.
己酸、1-辛醇、1,8-辛二醇、辛酸己酯、1,8-辛二醇单己酸酯和 1,8-辛二醇二己酸酯是从 Parallelostethus attenuatus (Say) （Elaterinae，Elaterini 部落）雌性叩头虫粉碎腹部采集的顶空挥发物中鉴定出的。在伊利诺伊州、南卡罗来纳州、北卡罗来纳州和弗吉尼亚州进行的野外试验中，成年雄性甲虫强烈地被 1,8-辛二醇二己酸酯单独吸引。与一种或多种其他化合物的混合物证明不如二己酸酯单独具有吸引力，这表明该物种的信息素可能由一种单一化合物组成。这种信息素的对称二酯结构是一种新型天然产物，在昆虫信息素中似乎具有独特的结构。
