| 中文摘要: |
| 草地贪夜蛾Spodoptera frugiperda (J. E. Smith)于2019年5月入侵贵州黔东南地区, 严重威胁当地农业生态。黔东南地区丰富的生物资源是挖掘草地贪夜蛾自然天敌的重要基础。为明确黔东南地区草地贪夜蛾天敌的发生情况, 2019年5月至7月, 采用五点取样法对选取的3个地点开展调查。结果表明, 草地贪夜蛾在黔东南地区的主要寄生性天敌有5类, 分别为白僵菌属、绿僵菌属、茧蜂科、姬蜂科和黑卵蜂属昆虫, 寄生率最高分别为45.50%、57.00%、3.00%、20.00%和12.50%, 寄生草地贪夜蛾幼虫期4种天敌综合控制力最高达96.50%。本研究可为草地贪夜蛾天敌资源挖掘与利用提供重要参考。 |
| 英文摘要: |
| Spodoptera frugiperda (J. E. Smith) has invaded southeast of Guizhou province since May of 2019, and posed a great threat to local agricultural production. The resources of natural enemies, which are potentially effective biological control agents against S.frugiperda, may be rich due to the particularly abundant biodiversity in southeastern Guizhou. To investigate the parasitic natural enemies of S.frugiperda, a five-point sampling method was used to investigate the natural enemies and their parasitism rates at 3 selected sites from May to July in 2019. The results showed that five types of parasitic natural enemy were found in this region, including Beauveria, Metarhizium, Braconidae, Ichneumonidae and Telenomus, and the max parasitism rates were 45.50%, 57.00%, 3.00%, 20.00%, and 12.50%, respectively. The total parasitism rate at larval stage of S.frugiperda could reach 96.50%. This study will provide a basic reference for the mining of natural enemy resources for the control of S.frugiperda. |
