【摘要】 对桔小实蝇Bactrocera dorsalisHendel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10.675 7℃、501.724 0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.更多还原

【Abstract】 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.更多还原
