中国农业大学研究人员在“四合一”的新背景下在全球的大尺度分布范围内研究了橘小实蝇的种群结构、定殖风险以及潜在分布,主要方法、结果与结论如下:(1)利用翅的几何形态学对橘小实蝇的六个组群,63个地理种群1216个个体的种群结构进行研究,结果表明橘小实蝇的翅形结构差异不明显,中国中部组群翅的质心大小最大,南亚组群翅的质心大小最小。(2)利用微卫星分子标记对橘小 Researchers at China Agricultural University studied the population structure, colonization risk and potential distribution of the fruit fly in the context of large-scale global distribution under the new background of “four in one”. The main methods, results and conclusions are as follows: (1) The population structure of 1216 individuals in six populations and 63 geographic populations of Diptera in the fruit fly were studied by means of geometric morphology of wings. The results showed that there was no significant difference in the wing structure of the fruit fly, The center of mass of the fin is the largest, and the center of mass of the wing of South Asia is the smallest. (2) the use of microsatellite markers orange small
