The Complete Mitochondrial Genome of Box Tree Moth and Insights into Phylogenetics in Pyraloidea.

To resolve and reconstruct phylogenetic relationships within Pyraloidea based on molecular data, the mitochondrial genome (mitogenome) was widely applied to understand phylogenetic relations at different taxonomic levels. In this research, a complete mitogenome of was recorded, and the phylogenetic position of was inferred based on the sequence in combination with other available sequence data. According to the research, the circular mitochondrial genome is 15,180 bp in length. It contains 22 transfer RNA genes (tRNAs), two ribosomal RNA genes (rRNAs), 13 typical protein-coding genes (PCGs), and a non-coding control region. The arrangement of a gene of the mitogenome is not the same as the putative ancestral arthropod mitogenome. All of the PCGs are initiated by ATN codons, except for the cytochrome c oxidase subunit 1 () gene, which is undertaken by CGA. Five genes have incomplete stop codons that contain only 'T'. All tRNA genes display a typical clover-leaf structure of mitochondrial tRNA, except for (AGN). The control region contained an 'ATAGG(A)'-like motif followed by a poly-T stretch. Based on the mitochondrial data, phylogenetic analysis within Pyraloidea was carried out using Bayesian inference (BI) and maximum likelihood (ML) analyses. Phylogenetic analysis showed that is more closely related to within Spilomelinae than those of Crambidae and Pyraloidea.
