The complete mitochondrial genome sequence of cabbage looper, Trichoplusia ni (Lepidoptera: Noctuidae)

Abstract

Trichoplusia ni is a polyphagous insect that feeds on many crops plants of economic importance. In this paper, we presented the complete mitochondrial genome of T. ni. The circular mitochondrial genome size is 15,239 bp, containing 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNA), two ribosome RNA genes (rRNA), and a control region of 1103 bp in length. The base composition of the genome is as follows: A of 38.9%, T of 41.6%, C of 11.5%, and G of 8.0%, with a total G + C content of the mitochondrial genome 19.5% and A + T of 80.5%. The phylogenetic Neighbour-Joining (NJ) tree was constructed to validate the taxonomic status of T. ni, exhibiting a closest relationship with Spodoptera litura and Spodoptera frugiperda. The research of the complete mitochondrial genome of Trichoplusia ni is able to provide a reference taxonomic relationships and more data of the insect for further.
