The complete mitochondrial genomes of aphids Aphis fabae mordvilkoi, A. craccivora, Myzus persicae from Aphidinae as well as Therioaphis tenera and Appendiseta robiniae from Calaphidinae were sequenced and compared with the genomes of other aphid species.A. fabae mordvilkoi, Th. tenera and A. robiniae mitogenomes were sequenced and analyzed for the first time. The annotation of A. craccivora and M. persicae were corrected compared to what was previously published. According to our data there is no translocation of tRNA-Tyr gene in A. craccivora mitogenome and this aphid species has an ancestral type of mitochondrial gene order.A + T content in all 5 mitogenomes was higher than 80%. A + T content in the Th. tenera CR was 59.5% which is untypically low. CRs of all 5 studied mitogenomes had 2 conserved motifs at their ends and extended G + C rich region. A. craccivora, M. persicae and Th. tenera had large tandem repeats inside the CRs.Detailed molecular analysis of all 5 aphid mitochondrial genomes showed the importance of a deep understanding of the molecular organization of all the functional regions of the mitochondrial DNA, which helps to avoid mistakes during genome annotation.
