Characterization of the complete mitochondrial genome of Asia Corn Borer, (Lepidoptera: Crambidae).

In this study, the complete mitogenome sequence of was described. The assembled mitogenome is 15,241 bp in length with an extreme bias of high AT content (80.9%) (GenBank accession no. MN747041). The mitochondrial genome contains 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, 2 ribosomal RNA (12S rRNA and 16S rRNA) genes, and a control region (D-loop region). The mitochondrial gene order was identical to that observed in most lepidopteran genomes, nine PCGs were located on the H-strand, others were located on the L-strand. 12 PCGs were initiated by typical ATN codons, except for with CGA instead. 21 tRNAs had the typical cloverleaf structure, while the DHU arm of the gene did not form a stable stem-loop structure. The 'ATAGT(A)'-like motif and a 19 bp poly-T stretch at the down-stream of the gene were observed in the A + T-rich region. The phylogenetic analysis showed that the relationship of is very close to the three species in the subfamily Pyraustinae: , and , and all the subfamilies of Spilomelinae, Pyraustinae, Crambinae and Nymphulinae within Crambidae formed monophyletic groups with the highest bootstrap value support.
