摘要
为了探究草地贪夜蛾的发生规律以及防治技术,本研究采用田间定点监测的调查方法,对其发生规律和危害原因进行分析,并提出了一系列绿色防控措施。结果表明,以2019年检测数据为基数,2022年草地贪夜蛾的成虫和幼虫的始见期推迟,平均虫株率和百株虫量分别下降了2.3%和20头,平均发生面积减少了2.18×10^(7)m^(2),平均防治成本减少了33.3×10^(4)元,这与掌握该害虫发生规律及绿色防控与统筹防治融合技术的应用相关。适时地实施绿色防控与统筹防治融合技术,控制虫源基数,实现内外虫源防控有机结合,为后期防治草地贪夜蛾提供思路。
In order to explore the occurrence rule and control technology of Spodoptera frugiperda,the method of monitoring in the field was selected.The occurrence rules and harm causes were then analyzed,and a series of green prevention and control measures were put forward.The results showed that based on the test date in 2019,the initial period of adults and larvae in 2022 was delayed,the average plant rate and the number of insect in 100 plants decreased by 2.3%and 20,respectively,the average occurrence area decreased by 2.18×10^(7)m^(2),the average control cost reduced by 33.3×10^(4)yuan,which was related to the mastery of the occurrence law of the pest and the application of green prevention and control and overall control integration technology.Timely implementation of green prevention and control and integrated control technology,control the pest base,realize the organic combination of internal and external insect prevention and control,to provide ideas for the later control of Spodoptera frugiperda.
