Complete Mitogenomic Structure and Phylogenetic Implications of the Genus (Lepidoptera: Crambidae).

To understand mitogenome characteristics and reveal phylogenetic relationships of the genus including several notorious pests of great importance for crops, we sequenced the complete mitogenomes of four species: (Guenée, 1854), (Hübner, 1796), (Walker, 1859) and (Guenée, 1854). Results indicate that the four mitogenomes-, , and -are 15,245, 15,248, 15,311, and 15,208 bp in size, respectively. All four mitogenomes are comprised of 37 encoded genes and a control region. All 13 protein-coding genes (PCGs) initiate with ATN and terminate with TAN, with the exception of that starts with CGA, and , , and that terminate with an incomplete codon T. All transfer RNA genes (tRNAs) present the typical clover-leaf secondary structure except for the (AGN) gene. There are some conserved structural elements in the control region. Our analyses indicate that and exhibit higher evolution rates compared to other PCGs. Phylogenetic analyses based on mitogenomes using both maximum likelihood (ML) and Bayesian inference (BI) methods revealed the relationship ( + ( + ( + ( + ( + ))))) within .
