摘　　要：采用诱剂诱捕辅以受害瓜果调查的方法,系统梳理了云南有害实蝇类群,确定主要有害种类25种。基于云南自然地理特征,采用聚类分析法深入探讨了云南实蝇区系,提出云南实蝇地理区划可分为德宏、版纳盆谷区,南部边缘中低山宽谷区,滇西南山原峡谷区,中东部高原、岩溶山原区以及北部高原山地区等5大区域。研究发现,受热量条件制约,云南主要有害实蝇类群呈南北向梯度递减;受纵向岭谷区"通道-阻隔"综合作用影响,云南西南部河谷地区是实蝇危害较为严重的区域。首次系统揭示了云南主要有害实蝇的地理分布规律。Fruit flies（Diptera： Tephritidae） and their geographic distribution were investigated by systematic trapping and large-scale surveys of damaged fruit in 2003-2007 in more than 100 counties in Yunnan,China.Twenty five species of Tephritidae were identified as the major fruit fly pests in Yunnan.Cluster analysis was used to explore relationships between the geographical distribution of the Yunnan Tephritidae species and several characteristics of the region′s physical geography.Overall,five zoogeographical zones were identified： Xishuangbanna and Dehong basin valley,south margin of Yunnan middle-low mountain and strath,southwestern Yunnan mountain plateau and valley,east-central Yunnan plateau and karst plateau,and northern Yunnan plateau mountain zone.Temperature was the critical condition in explaining the geographic distribution of the fruit flies in Yunnan.Tephritidae species diversity increased along a gradient from north to south in Yunnan,with the highest number of Tephritidae species recorded in the valley zones in the southwestern Yunnan.This is the first study to demonstrate the relationship of fruit fly pest diversity to geographical features in Yunnan.
