| 摘 要： | 三种赤眼蜂寄主选择性和寄生能力的实验结果表明，松毛虫赤眼蜂对亚洲玉米螟卵的寄主选择性和寄生能力最弱，其次为拟澳洲赤眼蜂，玉米螟赤眼蜂最强，寄主偏爱可塑性实验结果表明、对玉米螟卵选择性和寄生能力较弱的拟澳洲赤眼蜂，其寄主的低偏爱性是可塑的；而对玉米螟卵选择性和寄生能力较强的玉米螟赤眼蜂，在亚洲玉米螟卵繁殖几代后，其寄生能力变化不大。

| Abstract: | During choice and parasitization experiments with three Trichogramma species, T. dendrolimi showed the lowest choice preference and parasitizing capacity for Ostrinia fumacalis eggs, the lower were T. confusion, and T. ostriniae showed the strongest preference for O. fumacalis eggs. The rate of parasitization and the number of offspring were low when T. confusum were switched to O. fumacalis eggs from Corcyra cepholonia eggs, and they increased significantly after several successive generations of rearing on new hosts, Which indicated that the preference was plastic. In the case of T. ostriniae, little change was observed. |
