【摘要】 我们采用昆虫性信息素腺体漂洗结合色-质谱分析方法,从桑毛虫性信息素腺体中鉴定出四个戊酸十八碳烯酯.它们是异戊酸顺-7-十八碳烯酯(1a)(92％),异戊酸6-十八碳烯酯(1.4％),异戊酸9-十八碳烯酯(5％)和正戊酸6-十八碳烯酯(16％).大田诱蛾生测和触角电位试验证明1a有很强的生理活性,可用于桑毛虫的测报和防治试验.1a是新的性信息素结构,在毒蛾科中性信息素是异戊酸酯尚属首次发现.更多还原

【Abstract】 Four components, i. e. Z-7-octenyl isovalerate (92%), 6-octenyl isovalerate (1.4%), 6-octenyl n-valerate (1. 6%) and 9-octenyl isovalerate (5%) have been identified from the sex pheromone gland washings of Euproctis similis xanthocampa, as determined by GC-MS analysis, microozonolysis and methyl transesterification. The synthetic Z-7-octenyl isovalerate was showed to be as active as the virgin female moths both in the field test or on EAG responses. The isovalerate type of sex pheromone is discovered in Lymantriidae. for the first time.更多还原
