Abstract

(E4,E10)-dodecadienyl acetate (E4,E10-12∶OAc) is a newly discovered sex pheromone component of the tentiform leafminer,Phyllonorycter mespilella (Hübner). In apple orchards, traps baited with 1Μg ofE4,E1012∶OAc attractedP. mespilella in British Columbia andP. blancardella (F.) in Massachusetts and Nova Scotia. The compound was identified inP. mespilella by gas chromatographic-electroantennographic analysis (GC-EAD) of pheromone gland extracts, retention index calculations, EAD profiles toE3 toE10 dodecenyl acetates, and synthesis of candidate pheromone components. Even thoughE4,E10-12∶OAc was not detected in gland extracts by GC-mass spectroscopy, several factors indicate that it is female-produced. Antennal responses to gland extracts coincided with authenticE4,E10-12∶OAc on four GC columns with different retention characteristics.E4,E10-12∶OAc andE10-12∶OAc, a known female-produced pheromone component, elicited equally strong EAD responses. In field tests,E4,E10-12∶OAc was two to four times more attractive thanE10-12∶OAc. There was no additive or synergistic effect between the two components.

摘要

(E4,E10)-十二碳二烯基乙酸酯（E4,E10-12∶OAc）是潜叶蛾 Phyllonorycter mespilella（Hübner）新发现的性信息素成分之一。在苹果园里，用 1μME4,E1012∶OAc 诱饵的诱捕器在不列颠哥伦比亚省和马萨诸塞州以及新斯科舍省吸引了 Phyllonorycter mespilella 和 Phyllonorycter blancardella（F.）。通过对性信息素腺体提取物进行气相色谱-触角电位分析（GC-EAD）、保留指数计算、对 E3 到 E10 十二碳烯基乙酸酯的 EAD 图谱以及候选信息素成分的合成，在 Phyllonorycter mespilella 中鉴定出了该化合物。尽管 GC-质谱法未在腺体提取物中检测到 E4,E10-12∶OAc，但有几个因素表明它是由雌性产生的。触角对腺体提取物的反应与四种具有不同保留特性的 GC 柱上的真实 E4,E10-12∶OAc 相吻合。E4,E10-12∶OAc 和 E10-12∶OAc，一种已知的由雌性产生的性信息素成分，引起了同样强烈的 EAD 反应。在田间试验中，E4,E10-12∶OAc 的吸引力比 E10-12∶OAc 强两到四倍。这两种成分之间没有增效或协同作用。
