(E)-6,10-dimethyl-5,9-undecadien-2-ol (geranyl acetol), termed here fuscol, was identified as a male-produced pheromone emitted by Tetropium fuscum (F.) and Tetropium cinnamopterum Kirby. In field experiments, traps baited with synthetic fuscol alone were not significantly attractive, but the combination of fuscol plus host volatiles (a synthetic blend of monoterpenes plus ethanol) attracted significantly more male and female T. fuscum and female T. cinnamopterum than did host volatiles alone. This is the first homoterpenoid alcohol to be described in the Cerambycidae, and the first pheromone reported from the sub-family Spondylidinae.
（E）-6,10-二甲基-5,9-十一碳二烯-2-醇（香叶基丙酮醇），本文中称为fuscol，被鉴定为雄性云杉小蠹（Tetropium fuscum (F.)）和肉桂翅小蠹（Tetropium cinnamopterum Kirby）释放的一种性信息素。在田间试验中，仅用合成fuscol诱捕的诱捕器吸引力并不显著，但fuscol与寄主挥发物（单萜类化合物与乙醇的合成混合物）的组合比单独使用寄主挥发物吸引了更多的雄性和雌性云杉小蠹以及雌性肉桂翅小蠹。这是在天牛科中首次描述的同型萜醇，也是在脊虎天牛亚科中首次报道的性信息素。
