| 为明确草地贪夜蛾Spodoptera frugiperda在四川省不同地区的发生世代, 本文根据四川省2019年?2020年草地贪夜蛾虫情及2010年-2019年近10年气温数据, 利用有效积温法则对四川省草地贪夜蛾发生世代数进行预测, 并运用ArcGIS进行Kriging插值分析, 获得四川省草地贪夜蛾世代区划?结果表明, 基于2019年及2020年虫情和10年气温数据计算得到草地贪夜蛾在四川省发生世代数为0~6.40代?四川省草地贪夜蛾发生世代数总体上呈现由西北向东南?由东北向西南增加的趋势?四川省草地贪夜蛾发生世代可分为6个区:川西高原不足1代区, 盆地西南部?西北部2~4代区, 盆地中部?东北部3~5代区, 盆地西南部?南部4~6代区, 攀西周年繁殖5~7代区, 攀西0~5代区?本研究结果可为四川省草地贪夜蛾监测预警和防控提供参考? |

| In order to determine the number of generations of Spodoptera frugiperda in different areas of Sichuan province, the law of effective accumulated temperature was used to predict the generations of S. frugiperda in Sichuan based on the insect pest situation in 2019 and 2020 and meteorological data from 2010 to 2019, and ArcGIS was used to perform Kriging interpolation to divide the generations of S. frugiperda. The results showed that the number of generations of S. frugiperda in Sichuan calculated based on the insect pest situation of S. frugiperda in 2019 and 2020 and meteorological data from 2010 to 2019 was 0-6.40 generations. On the whole, the number of generations of S. frugiperda increased from northwest to southeast and from northeast to southwest in Sichuan. The generations of S. frugiperda in Sichuan province can be divided into six regions, and less than one generation area in Western Sichuan Plateau, 2-4 generations area in the southwest and northwest of Sichuan Basin, 3-5 generations area in the middle and northeast of Sichuan Basin, 4-6 generations area in the southwest and south of Sichuan Basin, 5-7 generations area of year-round breeding in Panxi region, and 0-5 generations area in Panxi region. These results provided a reference for monitoring, early warning and effective prevention and control of S. frugiperda in Sichuan province. |
