| 中文摘要: |
| 草地贪夜蛾 Spodoptera frugiperda (J. E. Smith)为新入侵我国的重大害虫, 对我国农业生产造成了巨大的威胁。为挖掘、评估及利用广西地区草地贪夜蛾的寄生蜂天敌资源, 于2019年8月至10月、2020年8月在南宁市玉米产区进行了草地贪夜蛾寄生蜂的调查。共发现夜蛾黑卵蜂 Telenomus remus (Nixon)和螟黄赤眼蜂 Trichogramma chilonis Ishii两种卵寄生蜂。两种寄生蜂存在竞争关系, 但对草地贪夜蛾卵具有良好的自然寄生效果, 2019年、2020年卵块总寄生率分别为80.43%和91.49%, 卵粒总寄生率分别为63.80%和71.35%。两种寄生蜂对卵块的共同寄生的效率高于各自单独寄生的效率。夜蛾黑卵蜂的寄生效率高于螟黄赤眼蜂的寄生效率。两种寄生蜂具有防控草地贪夜蛾的潜力和价值。 |
| 英文摘要: |
| Spodoptera frugiperda (J. E. Smith) has made great threat to agricultural production as an important newly invaded pest in China. To excavate, evaluate and utilize the resources of parasitoid wasps against the pest in Guangxi, an investigation was carried out in corn fields in Nanning from August to October 2019 and August 2020. Two egg parasitoid species, Telenomus remus (Nixon) and Trichogramma chilonis Ishii, were found. The results showed that there was high total parasitism of two parasitoid species on S. frugiperda eggs, though there was a competition between the two parasitoid species. The parasitism rates of egg masses and eggs were 80.43%, 63.80% in 2019 and 91.49%, 71.35% in 2020. The efficiency of parasitism by the two species together was higher than that by either parasitoid alone. The parasitism efficiency of T. remus was higher than that of T. chilonis. The two parasitoid species have great potential and value in controlling S. frugiperda . |
