【摘要】 采用触角电位及气-质联用分析方法，对梨星毛虫雌蛾在不同时期内性信息素的产生量及其性信息素化学结构进行了初步研究。结果表明，雌蛾产生性信息素的高峰期为上午7～8时，性信息素的化学结构为一元不饱和的十二碳稀酸丁酯类化合物。更多还原

【Abstract】 In this paper, we reported the studies on the sex pheromone amounts during different times and the identification of female sex pheromone of Illiberis pruni. The methods of electroantennogram (EAG) and GC-Ms spectral analyses were used. The results showed that (1 ) the maximunm amounts of female sex pheromone production occured in 7: 00～ 8: 00 am ; (2) the chemical structure of sex pheromone is an unsaturated butyl dodecenoate.更多还原
