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

Abstract

In this study, we sequenced the complete mitochondrial genome (mitogenome) of the pumpkin fruit fly, Bactrocera depressa (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 COI gene begins with TCG, which has been identified as the start codon for all Bactrocera COI genes. The 1004-bp A + T-rich region of B. depressa is the third longest, after B. minax and B. scutellata, of the Bactrocera species for which the whole mitogenome has been sequenced. Phylogenetic analysis using the 13 PCGs of Bactrocera species indicated that B. depressa is a sister to the sister group containing B. tau and B. cucurbitae with the highest nodal support (Bayesian posterior probability =1.0).
