The Oedaleus infernalis sauss (Orthoptera: Oedipodidae) is one of the main pests at the rice production area in China, and they mainly feed on leaves and grain of rice. The mitogenome was 15 898 bp long and composed of 13 protein-coding genes, 22 tRNA genes, two rRNA genes, and one putative control region. Most protein-coding genes started with a traditional ATN codon, and terminated with the mitochondria stop codon (TAA/TAG) or a single T-- base. The average A+T content of the O. infernalis sauss mitochondria! genome protein-coding sequence, rRNA, tRNA gene, and A+T-rich region was corresponding well to the A+T bias generally observed in insect mitochondria! genomes. Using the 12 protein-coding genes of O. infernalis sauss in this study, together with 15 other closely species, a preliminary phylogenetic analysis has been carried out.
