摘　　要：西花蓟马Frankliniella occidentalis（Pergande）对多种蔬菜、花卉、果树造成毁灭性危害。以气候数据库为基础，根据该虫的致死温度模型和有效积温模型，运用数学分析和地理信息系统技术，研究西花蓟马在中国的地理生态学。结果表明：该虫可在中国85．97％地区发生，1年发生5～19代，以8-16代为主。Frankliniella occidentalis （Pergande） was deemed to be lethal to vegetables, flowers and fruits. Based climate database and according to models of its fatal temperature and effective accumulated temperature, we studied and forecasted its geographical distribution regions and generations yearly in China by adopting mathematic analysis and using the technique of geographical information system. The results showed that its potential distribution areas were about 85.97 percent of lands in China, it would occurre 5 - 19 generations, mainly g - 16 generations in one year in China.
