Abstract

Proeulia triquetra Obraztsov (Lepidoptera: Tortricidae) is an occasional pest in fruit orchards in central-southern Chile. In order to develop species-specific lures for detection and monitoring of this species, we identified the female-produced sex pheromone. (Z)-11-Tetradecenyl acetate (Z11-14:OAc), (E)-9-dodecenyl acetate (E9-12:OAc), and (E)-11-Tetradecenyl acetate (E11-14:OAc) were identified as biologically active compounds present in female pheromone glands by solvent extraction of the gland and analysis of the extracts by gas chromatography-electroantennographic detection and gas chromatography-mass spectrometry. In field tests, lures baited with synthetic Z11-14:OAc and E9-12:OAc in a 10:1 ratio were highly attractive to males of the species.

摘要

三棱普罗夜蛾（Proeulia triquetra Obraztsov，鳞翅目：卷蛾科）是智利中南部果园的偶发性害虫。为了开发用于该物种检测和监测的种特异性诱捕剂，我们鉴定了雌虫产生的性信息素。通过对腺体进行溶剂萃取，并利用气相色谱-触角电位检测和气相色谱-质谱联用对提取物进行分析，确定了（Z）-11-十四碳烯乙酸酯（Z11-14:OAc）、（E）-9-十二碳烯乙酸酯（E9-12:OAc）和（E）-11-十四碳烯乙酸酯（E11-14:OAc）为存在于雌虫信息素腺体中的生物活性化合物。在田间试验中，以10:1比例用合成Z11-14:OAc和E9-12:OAc诱饵的诱捕剂对该物种的雄虫具有高度吸引力。
