Eleven compounds structurally similar to known lepidopterous pheromone components were identified in the extract from 18 calling female moths ofEuxoa drewseni (Staudinger). The identifications were done by gas chromatography-mass spectrometry and high-resolution gas chromatography with flame ionization and electroantennographic detectors simultaneously. Detector antennae were from five species of moths. In the field, male moths were specifically attracted to a three-component blend of dodecyl, (Z)-5-dodecenyl, and (Z)-7-tetradecenyl acetates in a ratio of 2∶6∶1. This blend at 1000 μg/rubber septum dispenser is recommended as a trap bait for monitoring purposes. Low concentrations of (Z)-7-dodecenyl acetate or (Z)-7-tetradecenol inhibited the attraction of moths to the three-component blend. (Z)-7-Pentadecenyl acetate functioned as a parapheromone in place of (Z)-7-tetradecenyl acetate in the pheromone blend, and they appear to react via the same antennal receptor.
从 18 只求偶雌蛾的提取物中鉴定出 11 种与已知鳞翅目昆虫性信息素成分结构相似的化合物。鉴定工作是通过气相色谱-质谱和同时带有火焰离子化和电触角检测的高分辨率气相色谱进行的。检测触角来自 5 种飞蛾。在野外，雄蛾被一种由十二烷基、（Z）-5-十二烯基和（Z）-7-十四烯基乙酸酯以 2∶6∶1 的比例组成的三组分混合物所吸引。这种混合物以 1000μg/橡胶隔垫分配器的浓度被推荐作为监测目的的诱捕剂。（Z）-7-十二烯基乙酸酯或（Z）-7-十四烯醇的低浓度会抑制飞蛾对三组分混合物的吸引力。（Z）-7-十五烯基乙酸酯在性信息素混合物中替代（Z）-7-十四烯基乙酸酯作为副信息素，它们似乎通过相同的触角受体起作用。
