摘　　要：为探究利用生物气候图预测林芝巴宜区常发及潜在性害虫发生情况。利用林芝巴宜区的气候资料,通过对巴宜区2018年-2022年间4月至9月的温度、相对湿度气候因素的整理和统计,绘制出气候图,然后利用气候图分析预测林芝巴宜区常发性害虫小菜蛾、苹果绵蚜、黏虫及潜在性害虫草地贪夜蛾、梨小食心虫在林芝市巴宜区的发生情况及活动规律。结果表明:林芝市巴宜区的温度、湿度气候图是小菜蛾的适生区,小菜蛾在该区容易爆发成灾;黏虫、苹果绵蚜在该区发生危害程度不大;梨小食心虫不适合在林芝巴宜区分布,草地贪夜蛾在该区潜在发生程度大。因此,建议加大对林芝市巴宜区常发性害虫与潜在性害虫的预测预报,尤其是加大对草地贪夜蛾的预测预报与检疫工作。To explore the use of bioclimatic diagrams for predicting frequent and potential pest occurrences in the Bayi District of Linzhi,climate data from the Bayi District was analyzed.By organizing and statistically analyzing the temperature and relative humidity data from April to September for the years 2018 to 2022,climatic diagrams were created.These diagrams were then used to analyze and predict the occurrence and activity patterns of common pests such as Plutella xylostella(Linnaeus),Eriosoma lanigerum(Hausmann)and Mythimna separata(Walker)as well as potential pests like Spodoptera frugiperda and Grapholita molesta in the Bayi District of Linzhi.The results indicated that the temperature and humidity climatic diagrams for the Bayi District showed it as a suitable habitat for Plutella xylostella(Linnaeus),making it prone to outbreaks in this area.Mythimna separata(Walker)and Eriosoma lanigerum(Hausmann)posed less threat in this district,while Grapholita molesta was unsuitable for distribution in Bayi.However,Spodoptera frugiperda showed a high potential for occurrence in this region.Therefore,it is recommended to enhance the prediction and monitoring of both frequent and potential pests in the Bayi District,with a particular focus on Spodoptera frugiperda.
