摘　　要：在实验室条件下用四臂嗅觉仪分别测定了卷蛾分索赤眼蜂Trichogrammatoidea bactrae、拟澳洲赤眼蜂Tri-chogramma confusum、微突赤眼蜂T.raoi、舟蛾赤眼蜂T.closlerae对来源于米蛾Corcyra cephalom ica卵、米蛾卵浸提液、米蛾腹部鳞片浸提液的利他素的嗅觉反应.结果表明,这4种赤眼蜂对米蛾利他素有明显的趋向反应,表现为600 s内,赤眼蜂在处理区的滞留时间比对照区的滞留时间明显延长,二者之间差异显著.The four-armed olfactometer was used to measure the olfactory response of Trichogrammatoidea bactrae Nagaraja, Trichogramma confusum Viggiani, T. raoi Nagaraja and T. closlerae Pang et Chen to the volatiles derived from eggs, hexane extract of egg surface and ventral squama of Corcyra cephalomica （Stainton） in laboratory. The results showed that adults of these four species of trichogrammatid prolonged their retention time in the treated areas, and indicated the kairomones from C. cephalomica could stimulate an intensive search behavior of adults.
