摘　　要：对桔小实蝇Bactrocera dorsalis Hendel在中国的适生性进行了研究，结果表明，该虫的世代发育起点温度和有效积温分别为10．6757℃、501．7240日度．根据桔小实蝇的致死温度、有效积温和生物气候相似距，构建了桔小实蝇适生性分析计算机模型．用中国670个气象站30年的气候资料运行该模型，将桔小实蝇在中国的定殖风险区划分为高度危险区、危险区、轻度危险区和安全区，分布北界为（30±2）°N，适生区面积占全国的31．64％，1年发生3～11代，以4～8代为主．The computer model of viability of Bactrocera doraslis Hendel was established based on its fatal temperature, accumulated effective temperature and bioclimate analogous distance. By using 30-year climate data of 670 meteoroligical stations in China to construct the model. The results showed that B. doraslis could occur 3 to 11 generations yearly in China, mainly 4-8 generations, and the viability areas were 31.64% in China, and the potential distribution areas in China could be divided into safe regions, low risk regions, risk regions and high risk regions, and the northern distribution threshold was nearly （30 ±2）°N.
