The potential geographic distribution of the peach fruit fly, Bactrocera （ Bactrocera ） zonata , in Tibet | 桃实蝇在西藏的适生性分析

Chinese. 摘　　要：［目的］ 明确桃实蝇在西藏的适生性，为科学制定检疫措施，防止其入侵和扩散，保护西藏水果的安全生产提供依据。［方法］ 以中国760个（西藏39个）气象站点的气象数据和桃实蝇生物学数据为基础，运用CLIMEX模型和ArcGIS分析相结合的方法对桃实蝇在中国，尤其是西藏的适生性进行分析。［结果］ 桃实蝇在我国具有较高的适生性，适生范围包括34个省、市（区），其中海南、广东的南部、福建的南部、广西、云南、四川、陕西南部、河南和湖北的北部以及台湾的大部分地区属于高度适生区。而桃实蝇在西藏有3个适生站点。［结论］ 我国很多地区是桃实蝇的适生区，并且高度和中度适生区的范围相对较大。存在桃实蝇入侵西藏并定殖危害的可能性。

English. [Objective] The potential geographic distribution of the peach fruit fly, Bactrocera （Bactrocera） zonata （Saunders） was analyzed to provide the basis for working out its quarantine measures, so as to prevent its invasion and spreading , and to protect fruit production in Tibet. [Method] The potential geographic distribution of peach fruit fly in China, especially in Tibet, using CLIMEX and ArcGIS, was evaluated, based on the biological data of the peach fruit fly and meteorological data from 760 weather sites in China, 39 of which in Tibet. [Result] It indicated that the suitable areas of peach fruit fly covered 34 provinces, municipalities and autonomous regions, in which vast areas of Hainan, south of Guangdong and Fujian, Guangxi, Yunnan, Sichuan, south of Shanxi, Henan, north of Hubei and most areas of Taiwan were of high suitability. Three weather sites of Tibet were suitable to the growth of peach fruit fly, in which Chayu was the moderately suitable district. [Conclusion] There were many suitable areas, including the highly and the moderately suitable districts, of peach fruit fly in our country. And it is possible for the invasion and colonization of peach fruit fly in Tibet.
