摘　　要：为评估替代寄主米蛾Corcyra cephalonica卵能否用于驯化天敌夜蛾黑卵蜂Telenomus remus及其驯化效果,通过分析不同驯化代数夜蛾黑卵蜂对米蛾卵的寄生效果,比较用米蛾卵驯化的F30代夜蛾黑卵蜂品系和用斜纹夜蛾Spodoptera litura卵驯化的夜蛾黑卵蜂品系的发育历期、寿命和寄生效果等生物学参数的差异。结果显示,用米蛾卵驯化的F1、F10和F30代夜蛾黑卵蜂对米蛾卵的寄生率分别为1.94%、16.14%和85.00%,子代蜂羽化率分别为4.76%、30.28%和85.72%,随着米蛾卵驯化代数增长,夜蛾黑卵蜂的寄生率和子代蜂羽化率均显著增加。用米蛾卵驯化的F30代夜蛾黑卵蜂品系的发育历期和雌成蜂寿命分别为12.67 d和6.92 d,前者显著长于用斜纹夜蛾驯化的夜蛾黑卵蜂品系,后者与用斜纹夜蛾驯化的夜蛾黑卵蜂品系无显著差异。用米蛾卵驯化的F30代夜蛾黑卵蜂品系和用斜纹夜蛾驯化的夜蛾黑卵蜂品系对斜纹夜蛾的寄生率分别为98.63%和99.04%,子代蜂羽化率分别为84.33%和80.81%,2个品系之间均无显著差异。表明米蛾卵是夜蛾黑卵蜂扩繁的优良替代寄主,在夜蛾黑卵蜂商品化应用及生物防治夜蛾科害虫方面有巨大潜力。This study aimed to evaluate the suitability of using the factitious host Corcyra cephalonica eggs for domesticating the natural enemy Telenomus remus and its effect on domestication.The parasitic effects of T.remus on different generations of domesticated C.cephalonica eggs were analyzed.Biological parameters including developmental period,female longevity,and parasitism efficacy were compared between the domesticated F30 generation of C.cephalonica eggs and Spodoptera litura eggs.The results showed that the parasitism rates for domesticated F1,F10,and F30 generations were 1.94%,16.14%,and 85.00%,respectively,with emergence rates of 4.76%,30.28% and 85.72%.Parasitism and emergence rates of T.remus reared on C.cephalonica eggs were significantly increased.The developmental duration and female longevity of the domesticated F30 generation of C.cephalonica eggs were 12.67 d and 6.92 d,respectively.Although the developmental duration was significantly extended compared to the domesticated S.litura strain,female longevity did not significantly differ.The parasitism and emergence rates of the domesticated F30 generation of C.cephalonica eggs were 98.63% and 84.33%,respectively,and for S.litura eggs were 99.04% and 80.81%,respectively,with no significant difference observed.These results indicate that C.cephalonica eggs are excellent factitious hosts for propagating T.remus,demonstrating significant potential for commercial application and biological control of Noctuidae pests.
