| 中文摘要: |
| 夜蛾黑卵蜂 Telenomus remus 是草地贪夜蛾 Spodoptera frugiperda 卵期的重要专性寄生蜂。本研究通过人工释放夜蛾黑卵蜂,利用释放回捕法于田间初步评价了夜蛾黑卵蜂对草地贪夜蛾卵的田间防效。结果显示,夜蛾黑卵蜂在田间对草地贪夜蛾卵块的寄生率达到100%,卵粒寄生率为84.39%,田间校正寄生率达83.54%。尽管试验全过程伴随有连续阴雨天气,但降雨对夜蛾黑卵蜂的田间防效未产生较大的负面影响。本研究是我国首例于田间应用夜蛾黑卵蜂防控草地贪夜蛾卵的报道,研究结果将为利用夜蛾黑卵蜂防控草地贪夜蛾提供重要参考。 |
| 英文摘要: |
| Telenomus remus is one of the most important egg parasitoids against Spodoptera frugiperda eggs. In this study, we investigated the field control efficacy of T. remus against S. frugiperda eggs by the release recapture method. The results showed that the parasitic rate of egg masses and eggs is 100% and 84.39%, respectively. The corrected parasitic rate of eggs is 83.54%. Though rainy weather continuous during the experimental period, the rain didn’t cause negative effect on the control efficacy of T. remus. Our study is the first report concerning the field control efficacy of T. remus against S. frugiperda eggs, and the results will provide the basic reference for the control of S. frugiperda by using T. remus . |
