桔小实蝇（Bactroceradorsalis）是双翅目实蝇科实蝇科实蝇属的一种重要害虫，主要分布于亚洲热带、亚热带和太平洋地区。尽管它的经济重要性，很少有研究已经解决了这个物种的广泛的遗传结构和潜在的源区的问题。这项初步研究试图推断这种害虫的原产地和它在亚洲的殖民途径。结合线粒体和微卫星标记，我们评估了在东南亚和中国收集的苍蝇种群的遗传多样性水平，遗传结构和基因流。一个复杂的和显着的遗传结构对应的地理格局被发现与这两种类型的分子标记。然而，在这两种情况下发现的遗传结构都相当弱，并且没有发现距离隔离的模式。多个长距离的传播事件和杂主机选择由这个物种可以解释的结果。这些复杂的模式可能受到人为介导的害虫从一个地区到另一个地区的运输和研究区域的复杂地形的影响。对于线粒体和微卫星数据，没有发现瓶颈或创始人事件的迹象。但在缅甸、越南和中国广东发现了最大的遗传多样性，并发现了不对称的迁移模式，这些结果为东南亚热带地区和中国南部沿海可能是该物种的原产地和种群向北扩展提供了间接证据。云南（中国）是一个接触带，已经从不同的来源殖民。越南和中国南部沿海的沿着地区可能主要是中国南部地区的殖民地。中国南部沿海地区也可能在中国中部和云南中部殖民。
Bactrocera dorsalis (Diptera: Tephritidae) is mainly distributed in tropical and subtropical Asia and in the Pacific region. Despite its economic importance, very few studies have addressed the question of the wide genetic structure and potential source area of this species. This pilot study attempts to infer the native region of this pest and its colonization pathways in Asia. Combining mitochondrial and microsatellite markers, we evaluated the level of genetic diversity, genetic structure, and the gene flow among fly populations collected across Southeast Asia and China. A complex and significant genetic structure corresponding to the geographic pattern was found with both types of molecular markers. However, the genetic structure found was rather weak in both cases, and no pattern of isolation by distance was identified. Multiple long-distance dispersal events and miscellaneous host selection by this species may explain the results. These complex patterns may have been influenced by human-mediated transportation of the pest from one area to another and the complex topography of the study region. For both mitochondrial and microsatellite data, no signs of bottleneck or founder events could be identified. Nonetheless, maximal genetic diversity was observed in Myanmar, Vietnam and Guangdong (China) and asymmetric migration patterns were found. These results provide indirect evidence that the tropical regions of Southeast Asia and southern coast of China may be considered as the native range of the species and the population expansion is northward. Yunnan (China) is a contact zone that has been colonized from different sources. Regions along the southern coast of Vietnam and China probably served to colonize mainly the southern region of China. Southern coastal regions of China may also have colonized central parts of China and of central Yunnan.
