摘　　要：为明确新疆小麦主要虫害的适生区划,以麦蚜、麦蜘蛛和麦红吸浆虫的生物学特性、流行主导因素及气象数据为基础,通过ArcGIS对其在新疆的适生区划进行预测。结果表明,3种虫害的适生区广泛分布于新疆北部,在新疆南部只有麦二叉蚜和麦长腿蜘蛛局部适生。麦二叉蚜、麦长管蚜、麦长腿蜘蛛、麦圆蜘蛛和麦红吸浆虫的适生区面积占比分别为31.99%、12.86%、56.97%、22.27%、21.56%。针对新疆小麦虫害的适生范围进行预测,对掌握虫害的发生分布情况和科学有效防治具有重要的指导意义。The study aims to clarify the potential geographical distribution of wheat pests in Xinjiang.The biological characteristics,occurrence dominant factors and meteorological data were used to predict the potential distribution of wheat aphids,wheat mites and Sitodiplosis mosellena in Xinjiang based on ArcGIS.The results showed that the pests potential occurrence areas are widely distributed in the northern of Xinjiang,and the Schizaphis graminum and Petrobia latens occurred locally in the southern of Xinjiang.The percentage of potential occurrence area of Schizaphis graminum,Sitobion avenae,Petrobia latens,Pentfaleus major and Sitodiplosis mosellena was 31.99%,12.86%,56.97%,22.27%and 21.56%,respectively.Therefore,the prediction and forecast of potential occurrence area on wheat pests in Xinjiang,could be significant to recognize the occurrence and distribution of wheat pests,and provide the scientific prevention and control on wheat pests.
