在拟盾蚧的性腺提取物和洗液中，每雌含有10-20 ng的性信息素主要成分Z-9-十二烯乙酸酯（Z_（9 -12）∶Ac），并含有一些相关化合物。这些化合物是E-9-十二碳烯乙酸酯（E9-12∶Ac）、Z-9-十二碳烯-1-醇（Z9-12∶OH）、12、16、18和20个碳原子的饱和乙酸酯，以及微量的双不饱和乙酸酯，初步鉴定为9，11-十二碳二烯乙酸酯。在与信息素有关的组分中，乙酸十八酯占优势，其含量是Z9 - 1-2 ∶Ac的1-2倍，有时为20-30倍。同样的化合物也被发现在现场收集的女性和effluvi.Z-9-十一碳烯基乙酸酯，这是一个男性引诱剂本身，也被发现在一个样本的女性effluvia。Z9 -12∶Ac是一种引诱剂。模棱两可的乙酸十二烷酯（12∶Ac）本身不具有引诱作用，但与主引诱剂一起使用时可增加雄虫的捕获量。18∶Ac的加入仅在Z9 -12∶Ac和12∶Ac同时存在时才能增强吸引力。风洞试验表明，18∶Ac也提高了定向障碍阈值，正如以前对12∶Ac所表明的那样。其他化合物，可能除了额外的饱和乙酸酯，对诱捕器捕获没有影响，或者在E9 -12∶Ac，Z9-12∶OH和E-9，11-十二碳二烯乙酸酯的情况下，在一定程度上具有抑制作用。Z9 -12∶Ac、12∶Ac和18∶Ac的比例大致相等时，可提供最佳的引诱剂混合物。迄今为止所知的模棱两可的。
Sex gland extracts and washes ofEupoecilia ambiguellacontain 10–20 ng/female of the primary sex pheromone componentZ-9-dodecenyl acetate (Z9–12∶Ac), accompanied by a number of related compounds. These areE-9-dodecenyl acetate (E9–12∶Ac),Z-9-dodecen-1-ol (Z9–12∶OH), saturated acetates of 12, 16, 18, and 20 carbons, and traces of a doubly unsaturated acetate, tentatively identified as a 9,11-dodecadienyl acetate. Octadecyl acetate predominates among the pheromone-related components, making up 1–2, occasionally 20–30 times the amount ofZ9–12∶Ac. The same compounds were also found in field-collected females and in effluvia.Z-9-Undecenyl acetate, which is a male attractant on its own, was also found in a sample of female effluvia. A hierarchy is observed in the ethological function of the pheromone components.Z9–12∶Ac is an attractant forE. ambiguellamales. Dodecyl acetate (12∶Ac) is not attractive on its own but augments male catch when added to the main attractant. Addition of 18∶Ac augments attraction only when bothZ9–12∶Ac and 12∶Ac are present. Windtunnel tests demonstrate that 18∶Ac also raises the disorientation threshold, as previously shown for 12∶Ac. Other compounds, with the possible exception of additional saturated acetates, had either no effect on trap catch or, in the case ofE9–12∶Ac,Z9–12∶OH, andE-9,11-dodecadienyl acetate, were inhibitory above a certain level. A blend of roughly equal parts ofZ9–12∶Ac, 12∶Ac, and 18∶Ac provides the best attractant blend forE. ambiguellaknown to date.
