title: The complete mitochondrial genome of the American black flour beetle Tribolium audax (Coleoptera: Tenebrionidae).
abstract: Flour beetles of the genus Tribolium are all pests of stored products and cause severe economic losses every year. The American black flour beetle Tribolium audax is one of the important pest species of flour beetle, and it is also an important quarantine insect. Here we sequenced and characterized the complete mitochondrial genome of T. audax, which was intercepted by Huangpu Custom in maize from America. The complete circular mitochondrial genome (mitogenome) of T. audax was 15,924 bp in length, containing 37 typical coding genes and one non-coding AT-rich region. The mitogenome of T. audax exhibits a gene arrangement and content identical to the most common type in insects. All protein coding genes (PCGs) are start with a typical ATN initiation codon, except for the cox1, which use AAC as its start codon instead of ATN. Eleven genes use standard complete termination codon (nine TAA, two TAG), whereas the nad4 and nad5 genes end with single T. Except for trnS1 (AGN), all tRNA genes display typical secondary cloverleaf structures as those of other insects. The sizes of the large and small ribosomal RNA genes are 1288 and 780 bp, respectively. The AT content of the AT-rich region is 81.36%. The 5 bp conserved motif TACTA was found in the intergenic region between trnS2 (UCN) and nad1.
