(E14-18:Ald) and (E,E)-11,14-octadecadienal (E11,E14-18:Ald) were isolated and identified as major components from the pheromone glands of the tea cluster caterpillar,Andraca bipunctata, in Taiwan by analyzing the mass spectra of gland components and their DMDS adducts. GC retention times and mass spectra of the components were in agreement with those of authentic synthetic compounds. The average amount of 18:Ald
十八碳烯醛 (18:Ald)、(E)-11-十八碳烯醛 (E11-18:Ald)、(E)-14-十八碳烯醛 (E14-18:Ald) 和 (E,E)-11,14-十八碳烯醛 (E11)通过分析腺体成分及其 DMDS 加合物的质谱图,从台湾茶丛毛虫 Andraca bipunctata 的信息素腺体中分离并鉴定出 ,E14-18:Ald) 为主要成分。组分的 GC 保留时间和质谱与真实合成化合物的一致。18:Ald,E11-18:Ald,E14-18:Ald 和 E11,E14-18:Ald 每个雌性腺体(1 至 3 天大)的平均量为 121+/-76、50+/-20、187分别为 +/-75 和 237+/-110 ng,比例为 20:8:31:41。SyntheticE11,E14-18:Ald 在田间诱捕试验中比其他三种成分或空白对照捕获的雄性多。E11,E14-18:Ald 首次被报道为昆虫性信息素。在
