摘　　要：就甜菜夜蛾暴发成灾的重要因子进行了文献综述分析,并对其暴发成灾与全球气候异常现象(厄尔尼诺、拉尼娜现象)的关系进行了初步探讨,认为甜菜夜蛾暴发成灾是多种综合原因的共同作用结果。温度、降雨量、耕作制度均影响甜菜夜蛾的发生程度,全球气候异常是甜菜夜蛾大暴发的一个信号。进一步明确其暴发原因,找出其相关暴发因子的定量作用效果,并尽快建立其相关预警模型,是目前研究甜菜夜蛾预报和防治要解决的紧迫问题之一。The important factors of outbreak of beet armyworm are reviewed,while the relationship between outbreak of beet armyworm and climate anomaly （El Nio andLa Nia） is studied preliminarily.And it considers that the outbreak of beet armyworm is the result of interaction of the various factors.Further clarifying the reasons of outbreak,finding out the quantitative effect of outbreak factors and establishing the related warning model early is one of the urgent problems to be solved in research of forecasting and control of beet armyworm.
