Abstract

Z-8-Dodecenyl acetate (Z8-12∶Ac),E-8-dodecenyl acetate (E8-12∶Ac),Z-8-tetradecenyl acetate (Z8-14∶Ac),Z-10-tetradecenyl acetate (Z10-14∶Ac), andZ-8-dodecen-1-ol (Z8-12∶OH) were identified in the proportions 100∶1∶30∶5∶2 in female sex gland extracts ofGrapholita funebrana, accompanied by saturated acetates from 12 to 20 carbons with tetradecyl acetate predominating.Z10-14∶Ac has not previously been described as a lepidopteran sex pheromone component. Best attraction of males is obtained withZ8-12∶Ac in the presence of a higher proportion ofE8-12∶Ac than in the female. Inclusion of the 14-carbon acetates did not augmentG. funebrana catches but inhibitedG. molesta. On the other hand, addition ofZ8-12∶OH at the level optimal forG. molesta reduced attraction ofG. funebrana.

摘要

Z-8-十二烯基乙酸酯（Z8-12∶Ac）、E-8-十二烯基乙酸酯（E8-12∶Ac）、Z-8-十四烯基乙酸酯（Z8-14∶Ac）、Z-10-十四烯基乙酸酯（Z10-14∶Ac）和 Z-8-十二烯-1-醇（Z8-12∶OH）在舞毒蛾性腺提取物中的比例为 100∶1∶30∶5∶2，同时还存在从 12 到 20 个碳原子的饱和乙酸酯，其中以十四烷基乙酸酯为主。Z10-14∶Ac 以前并未被描述为鳞翅目性信息素成分。在存在较高比例的 E8-12∶Ac 的情况下，Z8-12∶Ac 对雄蛾具有最佳的吸引力，而在雌蛾中则不是这样。添加 14 碳乙酸酯并没有增加舞毒蛾的捕获量，但抑制了舞毒蛾的捕获量。另一方面，在对舞毒蛾最佳的水平下添加 Z8-12∶OH 会降低对舞毒蛾的吸引力。
