Characterization of the complete mitochondrial genome and phylogenetic analysis of bean thrips Megalurothrips usitatus (Bagnall, 1913) (Thysanoptera: thripidae)

Abstract

Megalurothrips usitatus (Bagnall, 1913) (Thysanoptera: Thripidae) is a widely distributed pest in Asia that primarily affects the production of snap beans and cowpea. The complete mitochondrial genome of Megalurothrips usitatus has been sequenced and annotated in this study, which is 17,209 bp long and contains 13 protein-coding genes (PCGs), two rRNAs, and 22 tRNA genes. Most of the protein-coding genes (PCGs) start with ATG except ND4 using TTG. Meanwhile, eight PCGs stop with TAA, four PCGs have an incomplete stop codon, and the gene Cytb ends with TAG. Phylogenetic analysis showed that M. usitatus is closely related to Frankliniella intonsa and F. occidentalis, providing a basis for the study of the mitochondrial evolution of Thripinae.
