摘要
桑尺蠖雌成虫性腺体漂洗液通过气相层析与触角电位联用（GC－EAD），测定出6种环氧类化合物具有明显的触角电位响应，大田生物测定结果表明，其中3Z，6Z－9S，10R环氧十八碳烃（SR－2）和6Z－9S，10R环氧十八碳烃（SR－1）为桑尺蠖的性信息素组分，这是一种新的性信息素结构。SR－2与SR－1的10：1混合物对桑尺蠖雄成虫具有最强的生物活性，可望用于桑尺蠖的性诱测报和防治试验。
Pheromone gland extract of female mulberry loopers were analysed with couple gaschromatographic-electron-tennographic detection (GC-EAD). It was discovered that itcontained six epoxides that could consistently elicit antennel response. The results ob-tained in the field experiment showed that (3Z, 6Z-9S, 10R)-epoxy-octadecadiene (SR-2) and (6Z-9S, 10R)-epoxy-octadecene (SR-1 ) in the six epoxides are sex pheromonecomponents,a new structure of the pheromone. SR-2 in binry combination with SR-1 as10: 1 was the most attractive to male mulberry loopers. So this mixture could be em-ployed for the experiments on monitoring, forecasting and controlling male populationof mulberry loopers.
