This study completes the sequencing and annotation of the mitochondrial genome (mitogenome) of Hyalopterus pruni (Hemiptera: Aphididae) by using the high-throughput sequencing. The mitogenome is a typical circular DNA of 15,410 bp with 86.2% A + T content, and consists of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, a repeat region between tRNA-Glu and tRNA-Phe, and a control region. The gene order follows the putative ancestral arrangements of insect mitogenome. All 13 protein-coding genes start with codon ATN and terminate with TAA or a single T. All tRNA genes have typical clover-leaf structure except for tRNA-SerAGN. The control region is 638 bp in length with 86.0% A + T content. The phylogenetic tree supports the monophyly of Aphidini and Macrosiphini in Aphidinae and the sister relationship between Hyalopterus pruni and Schizaphis graminum.
