摘      要：In order to investigate molecular phylogenetic relationships of Drosophila immigransspecies group,nucleotide sequences of H2a-H2b spacer regions and partial nucleotide sequences of Cytochrome b gene for five specieses subgroup in Drosophila immigrans species group and *** which was selected as outgroup were acquired. Phylogenetic trees were reconstructed using maximum parsimony,maximum likelihood,neighbor joining and Bayesian methods based on H2a-H2b and Cyt b DNA sequences. The results indicated that Drosophila curviceps species subgroup is located at the base of molecular trees, diverged first in this group; the second clade is Drosophila quadrilineata species subgroup; the third is Drosophila hypocausta species subgroup; the fourth is Drosophila immigrans species subgroup; Drosophila nasuta species subgroup is the last diverged clade. Moreover,the phylogentic relationships of seven specieses in Drosophila nasuta subgroup was investigated.
