Abstract

(Z,E)-9,11-tetradecadienal (Z9,E11-14: Ald; 11%), (Z,E)-9,11,13-tetradecatrienal (Z9,E11, 13-14: Ald; 67%), (Z,E)-9,11-tetradecadienyl acetate (Z9,E11-14: Ac, 5.5%), and (Z,E)-9,11,13-tetradecatrienyl acetate (Z9,E11,13-14: Ac; 16.5%) were identified in the extracts of female pheromone glands ofStenoma cecropia (Lepidoptera: Elachistidae). From electroantennograms and single sensillum recordings, receptors toZ9,E11,13-14:Ald andZ9,E11-14: Ald were found on male antenna. Behavioral data were obtained from olfactometric tests in the laboratory and field trapping experiments in Colombia. It appeared that a blend ofZ9,E11,13-14:Ald (83%) andZ9,E11-14:Ald (17%) was attractive to males. These aldehydes are assumed to be components of the sex pheromone ofS. cecropia, whereas the acetates found in gland extracts might be precursors of the pheromone.

摘要

(Z,E)-9,11-十四碳二烯醛（Z9,E11-14：Ald；11%），(Z,E)-9,11,13-十四碳三烯醛（Z9,E11,13-14：Ald；67%），(Z,E)-9,11-十四碳二烯基乙酸酯（Z9,E11-14：Ac，5.5%）和(Z,E)-9,11,13-十四碳三烯基乙酸酯（Z9,E11,13-14：Ac；16.5%）在棉铃虫（鳞翅目：Elachistidae）雌蛾信息素腺体的提取物中被鉴定出来。从触角电图和单一感器记录中，发现雄性触角上存在对Z9,E11,13-14：Ald 和 Z9,E11-14：Ald 的受体。实验室嗅觉测定和哥伦比亚野外诱捕实验获得了行为数据。似乎 Z9,E11,13-14：Ald（83%）和 Z9,E11-14：Ald（17%）的混合物对雄性具有吸引力。这些醛类被认为是棉铃虫性信息素的成分，而在腺体提取物中发现的乙酸酯可能是信息素的前体。
