Abstract: A mitochondrial cytochrome oxidase I (COI) region was partially sequenced from 27 individuals of 5 geographic populations of Bactrocera dorsalis (Hendel) from Ruili, Jinghong, Yuanjiang, Huanian and Hekou of Yunnan Province, respectively. Transition was higher than transversion, without insertion and deletion. In total, 23 haplotypes were identified within the sequences, with 27 sites showing polymorphism and 2 haplotypes were shared. The Fst values among the 5 populations were 0.0364 - 0.1364 ( P > 0.05) and Nm 3.88 - 13.25. Phylogenetic trees of haplotypes were constructed by the N-J method. Haplotypes did not match with their geographic origin. All results showed that genetic differences existed among the 5 populations at a lower degree. The main reason of the genetic differentiation among the 5 populations should be related to genetic isolation, development history and ecology adaptation of Bactrocera dorsalis.
