| 摘 要： | 夜蛾黑卵蜂Telenomus remus Nixon是多种鳞翅目夜蛾科昆虫卵期重要的寄生性天敌。本研究观测了夜蛾黑卵蜂对5种供试寄主卵（斜纹夜蛾Spodoptera litura、草地贪夜蛾Spodoptera frugiperda、甜菜夜蛾Spodoptera exigua、烟青虫Helicoverpa assulta和棉铃虫Helicoverpa armigera）的寄生及子代发育情况，比较了不同寄主卵繁育的夜蛾黑卵蜂在寄生率、羽化率、雌性比和体型大小等生物学指标的差异。结果表明：夜蛾黑卵蜂对斜纹夜蛾的卵粒寄生率最高，为94.48%；其次是草地贪夜蛾（92.11%）；对烟青虫和棉铃虫的卵粒寄生率相对较低，为34.08%和50.75%。草地贪夜蛾卵育出的子代雌蜂的后足胫节长度166.48 μm，比斜纹夜蛾卵繁育的159.22 μm大，但其羽化率较低，仅为68.06%，显著低于斜纹夜蛾的92.40%，斜纹夜蛾的单雌产卵量显著高于其他4种寄主。研究结果显示斜纹夜蛾卵是规模化繁育夜蛾黑卵蜂的理想中间寄主。

| Abstract: | Telenomus remus Nixon is an important egg parasitic natural enemy of a variety of noctuid insects (Lepidoptera: Noctuidae). In this study, the parasitism and offspring development of T. remus on 5 host species (Spodoptera litura, Spodoptera frugiperda, Spodoptera exigua, Helicoverpa assulta, and Helicoverpa armigera) were compared in terms of parasitism rate, emergence rate, female ratio, and body size. The results showed that T. remus had the highest parasitism rate on S. litura eggs (94.48%), followed by S. frugiperda eggs (92.11%), and lower rates on H. assulta and H. armigera eggs (34.08% and 50.75%, respectively). The tibia of hind leg of female T. remus emerging from the eggs of S. frugiperda (166.48 μm) was longer than that of the female wasp emerging from the eggs of S. litura (159.22 μm). However, the emergence rate was lower from the eggs of S. frugiperda (68.06%) than that from the eggs of S. litura (92.04%). Fecundity was higher in wasps emerging from S. litura eggs than from eggs of the other four host species. These results indicated that S. litura could be a promising host for mass rearing of T. remus. |
