Mitochondrial DNA B Resour. 2022 Feb 7;7(2):358-360. doi: 10.1080/23802359.2022.2035280. eCollection 2022.

Abstract

Leptinotarsa decemlineata Say 1824, an invasive and globally devastating beetle, inflicts great damage to potato crops worldwide. The complete mitogenome of L. decemlineata is described in this study. It is a 16,741 bp long circular DNA molecule with a high A + T content of 76.9%, containing a typical 37 gene pattern. All PCGs (protein-coding genes) initiate with typical ATN codons. Most PCGs use TAN as a stop codon, whereas ND4 and COX3 use the incomplete codon TA as the stop codon. The lengths of rrnL and rrnS genes are 1,337 bp and 811 bp, respectively. All 22 tRNAs ranged from 62 to 77 bp. Phylogenetic analysis of Chrysomelidae indicated that L. decemlineata clusteres with three other Chrysomelinae species, which is consistent with previous analyses.
