Abstract:

Anomala corpulenta is an important agricultural and forestry insect pest. In the present study, high-throughput sequencing of A. corpulenta mitochondrial genome was performed using the Illumina HiSeq X platform and the genome sequences were assembled and annotated. Then the structure features and base composition of A. corpulenta mitochondrial genome were analyzed. Based on the nucleotide sequences of 13 protein-coding genes(PCGs), the maximum likelihood and Bayesian methods were used to reconstruct the phylogenetic relationship of Scarabaeidae. The results showed that the complete mitogenome of Anomala corpulenta was 16 673 bp in size, including 13 PCGs, 22 tRNA genes, 2 rRNA genes and an A+T region with the length of 1 074 bp. The gene arrangement is consistent with those of the known insect species of Rutelinae, and follows the ancestral pattern without gene rearrangement. Phylogenetic analysis showed that all species of Rutelinae belonged to the same branch, confirming Rutelinae to be a monophyly. Genus Anomala was more closely related to Mimela than to Popillia or Adoretus. This is the first report of a complete mitochondrial genome of genus Anomala, the largest genus of Rutelinae, and it will contribute to increasing our knowledge about the mitogenomics and the phylogeny of Rutelinae.
