摘  要：
电生理试验显示出:大螟Sesamia inferens(Walker)雄蛾触角对Z11-16:Ac(A)oZ11-16:OH(B)激起强烈的触角电位(EAG)反应,Z11-16:ALD(C),E11-16:Ac(D),Z9-14:Ac(E)和Z7-12:Ac(F)四种化合物也能激起较强的EAG反应;A化合物的刺激阈比B高,此两种化合物5:5比例时,激起的反应最强烈。电生理的试验推测,雄蛾触角对A和B两种化合物的感受,是通过触角内两种不同类型的嗅觉感受器。A和B不同比例混合后,田间诱蛾试验证明:在9:1,8:2,5:5的比例时,其诱蛾量远远超过单独的A化合物;E加入A与B的混合物中,起抑制诱蛾的效果,上述试验表明,Z11-16:OH是大螟的性诱剂。

摘  要：
Eleetropliysiological investigations showed that the male antennae of purple stem borer moth (Sesamia inferens) produced high eleetroantennograni (EAG) responses to Z11-liexadec,enyl acetate (Z11-16 :Ac) and Z11-hexadeeenol (Z11-16 :OH) while Z11-hexa-decenal (Z11-16 :Ald), E11-hexadecenyl acetate, Z9-tetradecenyl aceate (Z9-14:Ac) and Z7-dodecenyl acetate (Z7-12:Ac) would induce lower EAG responses as compared with Z11-16 :Ac and Z11-16 :OH. Z11-16 :OH elicited response with threshold significantly lower than Z11-16:Ac and the results indicated that these two compounds might have different olfactory receptors. Combination of these two compounds in different proportions was tested for the attraction to the male moths in the field, and Zll-16 :Ac and Z11-16 :OH in 9:1, 8:1 and 5:5 ware found more potent than Zll-16 :Ac used alone, Z9-14 :Ac stowed inhibitory effect when mixed with Zll-16 :Ac and Zll-16 :OH in the field test for attraction of the male moths. The results of laboratory investigations and field tests suggest that Z11-16 :OH is the sex attactant or its component of the purple stem moths.
