【摘要】 本文通过比较拟澳洲赤眼蜂（Trichogrammaconfusum）在不同卵壳厚度的寄主卵-米蛾卵、小菜蛾卵和柞蚕卵上的产卵时间（完成一次产卵动作所需的时间，从开始穿刺到拔出产卵管止）、寿命、产卵历期和产卵量，表明寄主卵壳厚度对它们有较大的影响。在卵壳较薄的米蛾卵，产卵时间为1分6秒，雌蜂平均寿命为12．55天，产卵有效历期为10．64天，产卵雌蜂的平均产卵量为146．64粒。在小菜蛾卵上雌蜂平均寿命是12．74天，产卵历期10．98天，产卵量134．17，产卵雌蜂比96.05％．在卵壳较厚的柞蚕卵，产卵时间为1小时16分，雌蜂平均寿命为795天，成功的产卵历期为113天，产卵雌蜂的平均产卵量为47.21粒。可见，拟澳洲赤眼蜂在这三种寄主上的上述各项指标间存在着明显的差异。其原因可能为在卵壳较厚的柞产卵上，拟澳洲赤眼蜂需较长的时间去完成每一产卵过程，因而消耗能量大，并且有效的产卵主要集中在第1.2天，以后尽管拟澳洲赤眼蜂有产卵动作，但不再产出后代。更多还原

【Abstract】 The time of oviposition (from the beginning of drilling in the host egg to the pulling out bythe ovipositor), longevity, ovipositional duration and fecundity of Trichogramma confusum on theeggs of Corcyra cephalonica, diamondback moth(Plutella xylostella, DBM) and Antheraea pernyiwere significantly different, The time of oviposition on the egg of C. Cephalonica, and A. pernyiwas 1 minute 16 secondand 1 hour 16 minute, respectively. The longevity of female wasp on egg ofC. cephalonica, DBM and A. pernyi was 12.55, 12.74 and 7 .95 day respectively, The oviposi-tional duration on the three kinds of host egg was 10.64, 10.98and 1. 13 days. The ratio of femalewaspa laidd eggs on the three kinds of host egg was 96.87,96.05,and 60. 87% respectively. The fe-cundity of female wasp in average on three kinds of host egg was 146.64, 134. 17, and 47.21, re-spectively.These seem to be closely related to different thickness of the chorions of three hosts. Thepossible cause of these differences is suggested.更多还原
