摘  要：
[目的]摸清山西不同地域蔬菜田夜蛾科害虫的种群动态及优势种,揭示其与气候变量的关系,为菜田害虫防治提供理论依据.[方法]采用田间监测、分类鉴定、标本制作、数据处理的方法,对夜蛾科害虫动态趋势进行研究.[结果]2015—2016年,新绛县、太谷县、忻府区的夜蛾科种群数量高峰主要集中在6、7、8月.新绛县、太谷县的优势种为甘蓝夜蛾、甜菜夜蛾、斜纹夜蛾;忻府区的优势种为甜菜夜蛾、斜纹夜蛾、银纹夜蛾.不同地域不同优势种的数量高峰月份不同.夜蛾科的种群动态与三地的温度关系密切.新绛县的3种优势种的种群数量变化与月均低温的相关性最显著;太谷县的甘蓝夜蛾的种群数量变化与月均低温的相关性最显著;忻府区的3种优势种的种群数量与月均高温的相关性最显著.[结论]夜蛾科害虫种群动态变化是多因素相互作用的结果,需进一步研究.

摘  要：
[Objective] The aim was to study the population dynamics and dominant species, and the relationship between climatic variables of the insect pest in different areas of Shanxi province, and to provide theoretical basis for pest control. [Method] Through field monitoring, classification and identification, specimen making, data processing methods, the dynamic trend of insect pest of Noctuidae was researched. [Result] In 2015-2016, the highest population number of Noctuidae in Xinjiang County, Taigu County and Xinfu District were mainly in June,July and August, respectively. The dominant species were Mamestra brassicae Linnaeus,Spodoptera exigua,Spodoptera litura Fabricius in Xinjiang and Taigu County. The dominant species were Spodoptera exigua,Spodoptera litura Fabricius and Argyrogramma agnata Staudinger in Xinfu District. The number of different dominant species in different regions varied from month to month. The population dynamics of Noctuidae were closely related to the temperature of the three regions. The correlation between the population variation of three dominant species and the mean monthly maximum temperature was most significant in Xinjiang County. The correlation between the population variation of Mamestra brassicae Linnaeus and the mean monthly maximum temperature was most significant in Taigu County. The correlation between the population variation of three dominant species and the monthly mean maximum temperature was most significant in Xinfu District. [Conclusion] The fluctuation of population dynamics of the insect pest of Noctuidae is the result of many factors interact with each other, and further research is needed.
