Four components, (Z)-9-tetradecenal (8.6%), (Z,E)-9,12-tetradecadienal (4.8%), (Z)-11-hexadecenal (49.5%), and (Z)-13-octadecenal (37.1%), were identified in extracts of female pheromone glands of the European sunflower moth,Homoeosoma nebulellum (Lepidoptera: Pyralidae) using GC and GC-MS analyses. EAG and single-cell recordings of male antennal receptors gave strong evidence for (Z,E)-9,12-tetradecadienal as the antennal key compound of sex pheromone detection in this species. This result was confirmed by field trapping; removal of (Z,E)-9,12-tetradecadienal from quaternary blends completely suppressed the male catches. The synthetic blends with this compound as a major component caught five times less males than the blends reproducing the ratio found in the female extracts [5% of (Z,E)-9,12-tetradecadienal only]. The occurrence of a minor component perceived as the most biologically relevant compound is discussed.
四种成分,(Z)-9-十四碳烯醛(8.6%)、(Z,E)-9,12-十四碳二烯醛(4.8%)、(Z)-11-十六碳烯醛(49.5%)和(Z)-13-十八碳烯醛(37.1%),使用 GC 和 GC-MS 分析从欧洲向日葵夜蛾,Homoeosoma nebulellum(鳞翅目:Pyralidae)的雌性信息素腺体提取物中鉴定出来。EAG 和雄性触角单细胞记录为(Z,E)-9,12-十四碳二烯醛作为该物种性信息素检测的触角关键化合物提供了强有力的证据。这一结果通过野外诱捕得到了证实;从四元混合物中去除(Z,E)-9,12-十四碳二烯醛完全抑制了雄性的捕获。含有这种化合物作为主要成分的合成混合物比再现雌性提取物中发现的比例的混合物少捕获五倍的雄性[仅含有 5%的(Z,E)-9,12-十四碳二烯醛]。讨论了一种被认为是最具生物学相关性的次要成分的存在。
