摘　　要：To analyze the genetic differentiation of the host- and geo-populations of Liriomyza sativae Blanchard, the β-tubulin gene of 5 host-populations and 6 geo-populations of L. sativae was sequenced. Subsequently, the sequences were analyzed by biosoftware DNAStar and MEGA, and the phylogenetic trees constructed. The results obtained by the two softwares were similar, that is, the sequences of β-tubulin gene were more than 98% homologous, among the host- and geo-populations of L. sativae, with only 8 variable sites, but no insertions and deletions were detected. It seems that differentiations in β-tubulin gene among the host- and geo-populations of L. sativae are related to the hobby to hosts and the geographical distributions, respectively.To analyze the genetic differentiation of the host- and geo-populations of Liriomyza sativae Blanchard, the β-tubulin gene of 5 host-populations and 6 geo-populations of L. sativae was sequenced.
