Complete mitochondrial genome of a parasitoid, Trichogramma chilonis (Hymenoptera: Chalcidoidea: Trichogrammatidae) and phylogenetic analysis

Abstract

Trichogramma chilonis is a kind of ovoid parasitic wasp, which has important application value in the biological control of pests. In this study, we sequenced and analyzed the complete mitogenome T. chilonis to compare mitogenomic structures and reconstruct phylogenetic relationships. The complete mitogenome sequence of T. chilonis is circular, 16,176 bp in size and encodes 13 protein-coding genes (PCGs), 2 ribosomal RNA genes (rRNA), 22 transfer RNA genes (tRNA), and a control region (CR). Nucleotide composition is highly biased toward A + T nucleotides (85.2%). All 13 protein-coding genes (PCGs) initiate with the standard start codon of ATN and terminate with the typical stop codon TAA/TAG. Phylogenetic analyses were performed using amino acids of 13 PCGs showed that T. chilonis is closely related to Trichogramma ostriniae.
