Complete mitochondrial genome of the pumpkin fruit fly,<i>Bactrocera depressa</i>(Diptera: Tephritidae)

Abstract

In this study, we sequenced the complete mitochondrial genome (mitogenome) of the pumpkin fruit fly, <i>Bactrocera depressa</i> (Diptera: Tephritidae), which is an economically damaging pest of pumpkin and turban squash. The 15,832-bp-long complete mitogenome of the species consists of a typical set of genes, with an arrangement typical of insects. Of the 13 protein-coding genes (PCGs), 12 have a typical ATN start codon, whereas the <i>COI</i> gene begins with TCG, which has been identified as the start codon for all <i>Bactrocera COI</i> genes. The 1004-bp A + T-rich region of <i>B. depressa</i> is the third longest, after <i>B. minax</i> and <i>B. scutellata</i>, of the <i>Bactrocera</i> species for which the whole mitogenome has been sequenced. Phylogenetic analysis using the 13 PCGs of <i>Bactrocera</i> species indicated that <i>B. depressa</i> is a sister to the sister group containing <i>B. tau</i> and <i>B. cucurbitae</i> with the highest nodal support (Bayesian posterior probability =1.0).
