Abstract

The stick tea thrips, Dendrothrips minowai Priesner (Thysanoptera: Thripidae), is a major pest of tea plantation and poses a considerable economic threat to tea industry. The mitochondrial genome of D. minowai have been sequenced and annotated completely. The entire genome is 14,631 bp in length with an A + T content of 78.53% (GenBank accession No. MF582634). The stick tea thrips mt genome encodes all 37 genes that are typically found in animal mt genomes, consists of 13 protein-coding genes, two ribosomal RNA genes, and 22 transfer RNA genes. The gene order is unique and different from that of the other thrips. The A + T-rich region is 149 bp long and contains two poly-T stretchs. Phylogenetic analysis was performed using 13 protein-coding genes with six thrips showed that D. minowai and other five Thripidae species were clustered into a branch, which is formed a sister clade to H. aculeatus (family Phlaeothripidae).

Highlights

  • The stick tea thrips, Dendrothrips minowai Priesner (Thysanoptera: Thripidae), is a major pest of tea plantation and poses a considerable economic threat to tea industry

  • The mt genome of D. minowai encodes all 37 genes usually found in animal mt genomes, including 13 protein-coding genes (PCG), two ribosomal RNA genes, and 22 transfer RNA genes

  • All 22 tRNA genes usually found in the mt genomes of insects have been identified in D. minowai, 18 tRNA genes are encoded by the J-strand and the other four genes are encoded by the N-strand

Summary

Introduction

The stick tea thrips, Dendrothrips minowai Priesner (Thysanoptera: Thripidae), is a major pest of tea plantation and poses a considerable economic threat to tea industry. KEYWORDS Mitochondrial genome; Dendrothrips minowai; Thysanoptera; tea pest The stick tea thrips, Dendrothrips minowai Priesner (Thysanoptera: Thripidae), is a major pest of tea. The stick tea thrips samples were collected from the tea plantation at Yongchuan, Chongqing, China in 2016, subsequently identified to species by morphology.
