The sex pheromone of the pistachio twig borer, Kermania pistaciella (Lepidoptera: Oinophilidae), one of the most important insect pests of pistachio, Pistacia vera, in Turkey and Iran, was identified. In gas chromatographic-electroantennographic detection (GC-EAD) and GC-mass spectrometric analyses of pheromone gland extracts of female K. pistaciella from Turkey, (2S,12Z)-2-acetoxy-12-heptadecene was identified as the major candidate pheromone component. In field experiments in Turkey, lures containing synthetic (2S,12Z)-2-acetoxy-12-heptadecene attracted large numbers of male moths. Its attractiveness was significantly reduced by the presence of the R-enantiomer or of either enantiomer of the corresponding alcohol. (2S,12Z)-2-Acetoxy-12-heptadecene is the first pheromone component identified in the Oinophilidae and the first secondary acetate pheromone component identified in the Lepidoptera.
确定了开心果小枝钻蛀虫(Kermania pistaciella,鳞翅目:葡萄小蠹家族)性信息素,该虫是土耳其和伊朗中对开心果(Pistacia vera)最重要的害虫之一。在对来自土耳其的雌性K. pistaciella的性信息素腺提取物进行气相色谱-电生理检测(GC-EAD)和气相色谱-质谱分析中,识别出(2S,12Z)-2-乙氧基-12-庚十六烯作为主要候选信息素成分。在土耳其的田间实验中,含有合成(2S,12Z)-2-乙氧基-12-庚十六烯的诱饵吸引了大量雄蛾。其吸引力在存在R-对映体或相应醇的任何对映体时显著降低。(2S,12Z)-2-乙氧基-12-庚十六烯是葡萄小蠹家族中首次识别的信息素成分,也是鳞翅目中首次识别的次级乙酸酯信息素成分。
