| Popis: | Bactrocera biguttula is an African olive fruit fly that does not attack cultivated olives but rather develops in the fruits of wild species of Olea and Noronhia. The complete mitochondrial genome of an individual specimen was characterized in comparison to other Bactrocera. The phylogenetic relationships of B. biguttula with other Dacini were investigated, with special focus on B. oleae, an agricultural pest known to attack cultivated and wild olives. The sequence had a total length of 15,829 bp, and included the typical features of insect mitogenomes, similarly to the other Bactrocera analysed. Start codons included ATG, ATC, ATT, and TCG (in COI). The majority of stop codons (TAA) were fully encoded, whereas in some cases only TA or T were present. The complete sequence was biased towards A + T, with a positive AT-skew and a negative GC-skew. The predicted cloverleaf structure of tRNA(Ser1) showed absence of the DHU arm, a common feature in insects and other Metazoans. Phylogenetic reconstruction showed that B. biguttula and B. oleae are sister species, having diverged from a common ancestor < 10 Myr ago. This result warrants future genomic comparisons between these two closely related species for investigating the specific adaptations to the different hosts. (C) 2018 Elsevier B.V.
