摘  要：
雌蛾腺体内含量最高的组份Z9,E11 14∶Ac (A)在风洞中能引起雄蛾从搜索气迹、定向飞行到撒开味刷企图交尾连续的行为反应 ,而雌蛾腺体内其它组份单独使用时均不能引起雄蛾上述行为反应。一定量的Z9,E12 14∶Ac(B)对A的活性有增效作用 ,诱芯中B数量过多 ,不但失去对A的活性增效作用 ,还对雄蛾接近诱芯和企图交尾有强烈的抑制作用。Z9 14∶Ac (C)与E11 14∶Ac (D)对雄蛾的定向行为无影响 ,诱芯中含有 5 0 %的C时 ,反而对雄蛾接近诱芯和企图交尾有抑制作用。A与B在滤纸诱芯中的含量比例与诱芯释放的挥发物比例明显不同 ,从 9∶1(A∶B)诱芯释放的挥发物比例更接近于雌蛾腺体内的天然比例。田间诱捕试验中两组份诱芯的诱捕量随两组份比例不同而变化 ,9∶1(A∶B)诱芯的诱捕量最大 ,1∶1(A∶B)诱芯的诱捕量低于单一的A组份诱芯。

摘  要：
The major component of the sex pheromone of S. litura (F.) female, Z9,E11-14∶Ac(A), elicited all steps of the male behavioral sequence, i. e., searching for the odor, oriented upwind flight, approaching the source and displaying hairpencils. No males showed oriented flight when Z9,E12-14∶Ac(B),Z9-14∶Ac(C), E11-14∶Ac(D) were assayed individually. Component B was able to enhance the activity of A, but larger amount of B in mixture strongly inhibited males from approaching the source and displaying hairpencils. The components of C and D had no effect on male behavior, but larger amount of C in a mixture of A and B inhibited males approaching the source and displaying hairpencils. There was a significant difference between the ratio of A to B in the filter paper lure and that in volatile from the filter paper lure. The ratio of A to B in volatile from the most effective lure in the wind tunnel was approximate to the natural ratio of A to B in the sex pheromone gland. In the field, the attractiveness of trap for male moths changed with the ratio of the components with most males being caught in traps baited with a ratio of 9∶1(A∶B). The attractiveness of traps with ratios of 1∶1(A∶B) was lower than the attractiveness of traps baited with single component A.
