Abstract:Mitochondrial genes represent important molecular clocks for phylogenetic analysis. In present study, the complete mitochondrial genome of Cnaphalocrocis medinalis was sequenced, which is a circular molecule with 15 377 bp length (AT 82%). The genome structure shows a lepidopteron-unique CR-M-I-Q arrangement. Based on COX gene, we speculated phylogenetic relationship among 22 pterygotan insects species. The result suggests the evolution of insects was highly related to the divergence of their wings. Three types of model are proposed for the first time, to determine the termination codon of the animal mtDNAs.
