| 中文摘要: |
| 糖类是昆虫生长发育和繁殖所必需的营养物质, 为提高夜蛾黑卵蜂的扩繁效率及控害能力, 本研究在室内分别测定了饲喂10%、15%、20%的葡萄糖和蔗糖对夜蛾黑卵蜂成蜂繁殖力、寿命及子代羽化率的影响。结果表明:以斜纹夜蛾卵或草地贪夜蛾卵为寄主扩繁夜蛾黑卵蜂时, 饲喂20%葡萄糖或蔗糖的夜蛾黑卵蜂雌蜂寿命最长, 且葡萄糖对雌蜂寿命的延长效果显著高于蔗糖。饲喂10%葡萄糖或蔗糖的雌蜂产卵量最高;其中以斜纹夜蛾卵为寄主时, 葡萄糖对雌蜂产卵量的增加作用显著高于蔗糖;但以草地贪夜蛾卵为寄主时, 饲喂蔗糖的促产卵效果优于葡萄糖。寄主相同时, 蔗糖对提高夜蛾黑卵蜂子代羽化率和雌性比的效果显著强于葡萄糖。本研究证明，补充20%葡萄糖能显著延长夜蛾黑卵蜂的寿命, 补充蔗糖可有效提高其繁殖力, 试验结果可为提高夜蛾黑卵蜂的大量扩繁能力和防控应用提供参考依据。 |

| Sugars are essential nutrients for the growth, development, and reproduction of insects. To enhance the reproductive efficiency and biocontrol ability of the egg parasitoid, Telenomus remus, the effects of feeding on different concentrations of glucose and sucrose (10%, 15%, and 20%, respectively) on fecundity, longevity of T.remus and emergence rate of offspring were determined. The results indicated that female adults of T.remus fed with either 20% glucose or sucrose exhibited the longest longevity when eggs of Spodoptera litura or S.frugiperda were as the host. Additionally, glucose demonstrated a more pronounced prolongation effect on female lifespan compared to sucrose. The highest egg production was observed in individuals fed with either 10% glucose or sucrose. Furthermore, the effect of glucose on enhancing fecundity was significantly higher than that of sucrose when using S.litura eggs as hosts. However, sucrose outperformed glucose in promoting oviposition when exploiting S.frugiperda eggs as hosts. Moreover, sucrose proved more effective than glucose in elevating the eclosion rate and female ratio in the progeny of T.remus when reared on the same host type. This study underscored the significant prolongation of T.remus lifespan with the supplementation of 20% glucose, and the dramatic enhancement of parasitoid fecundity through sucrose augmentation. These insights provide valuable references for improving the large-scale production and application of the egg parasitoid T.remus in biological control. |
