A Phytogeny Based on 13 Mitochondrial Protein Coding Genes (PCGs) within Tephritidae of Diptera

摘要

The objective of this study was to infer phylogenetic relationships among 8 sequenced mitochondrial genomes within Tephritidae of Diptera. According to conserved (C) / variable (V) sites ratio test, we combined all 13 mtDNA protein coding genes (PCGs) into a single data set for use in determining phylogeny. The same gene regions of Pteronarcys princes, Lucilia sericata and Drosophila yakuba were used as outgroup. When MP and ML analysis were applied to the combined data set, they gave two fairly similar trees. Accorded with all previous morphological and molecular evidence, the monophyly of family Tephritidae was strongly recovered in our result. Our data set led to a likelihood tree in which B. dorsalis and B. papayae was provided relative closely relationship meanwhile B. carambolae formed a clade basal to them. This result agreed with Zhang et al. (2010) and Nadi et al. (2010).
