The first complete mitochondrial genome of Adelges tsugae Annand (Hemiptera: Adelgidae)

Abstract

Hemlock wooly adelgid (HWA), Adelgests ugae Annand (Hemiptera: Adelgidae), is a species native to Asia but later ravages Endangered hemlock forests (Tsuga spp.) in eastern North America. In this study, we obtained the first complete mitochondrial genome of HWA (16,509 bp in length) using meta-genomic sequencing method. The HWA mitogenome has a general gene annotation as other aphids, comprising 13 protein-coding genes, 22 transfer RNAs, and 2 ribosomal RNAs. Our phylogenetic result showed Aphidoidea is sister to Coccoidea and the newly sequenced mitogenome is put on the correct position, sister to Adelgeslaricis.
