| 中文摘要:联合国粮食及农业组织2018年向全球发布草地贪夜蛾Spodoptera frugiperda是重要的预警害虫。据报道,2019年我国已有26个省(区、市)的作物受到草地贪夜蛾为害。目前已经发现草地贪夜蛾幼虫对某些化学农药产生抗性的现象,为缓解其抗药性产生,具有主动寻找寄主害虫的昆虫病原线虫为草地贪夜蛾的生物防治提供了应用潜能。该文从昆虫病原线虫高效侵染种(品系)及其浓度、共生菌、草地贪夜蛾幼虫易感龄期、田间致死力及影响防控效果的因素等方面进行综述,以期为田间有效利用昆虫病原线虫防治草地贪夜蛾提供参考。 |

| Abstract:The Food and Agriculture Organization of the United Nations announced in 2018 that fall armyworm Spodoptera frugiperda was an important early warning pest. It was reported that, up to 2019,26 provinces(regions and cities) in China have suffered from this pest. The larvae of S. frugiperda have developed resistance to some chemical pesticides. For alleviating the resistance, entomopathogenic nematode(EPN) featured with actively searching host pests have the potential for biocontrol of S. frugiperda. This review aimed to summarize the highly infective EPN species(strains) and their concentrations,the susceptible instars of S. frugiperda larvae, EPN symbiotic bacteria and highly efficient infection,EPN lethality to the larvae in fields and factors affecting the pest control efficiency. The hope is that it can provide useful information for EPN utilization in the field as an effective biological control agent against S. frugiperda. |
