云南草地贪夜蛾发生规律、主要影响因子及防控对策

Occurrence regularity,main influencing factors and control strategies of Spodoptera frugiperda in Yunnan

草地贪夜蛾(Spodoptera frugiperda)又称秋粘虫,是近两年经云南跨境入侵我国的重大农业害虫,对我国玉米种植业发展造成重大威胁.云南是草地贪夜蛾重灾区,也是境外草地贪夜蛾向我国内地迁移扩张的重要陆路通道.探究并揭示草地贪夜蛾在云南的发生发展规律,对于云南乃至全国草地贪夜蛾防控均具有重要意义.作者基于文献分析及前期研究,系统阐释了云南草地贪夜蛾发生的基本规律,探讨了影响云南草地贪夜蛾灾害形成的主要影响因子,提出了云南草地贪夜蛾防控对策.研究具有较强的地域性,明确的针对性,为开展云南草地贪夜蛾防控提供了科学指引.

Spodoptera frugiperda,known as fall armyworm(FAW)is the major agricultural pest that crossborder invade China through Yunnan in recent two years,which pose a great threat to the development of China's corn planting industry.Yunnan Province is a serious disaster area of the insect pest,and also an important land route for the migration and expansion of the alien pest to the inland areas of China.To explore and reveal the occurrence and development of S.frugiperda in Yunnan is of great significance for the prevention and control of the pest in Yunnan and even the whole country.Based on the literature analysis and previous research,this paper systematically explained the basic features of the pest occurrence,discussed the major factors affecting the formation of insect disasters,and put forward the prevention and control countermeasures of S.frugiperda in Yunnan.This study has strong regional and clear pertinence,which provides scientific guidance for S.frugiperda control.
