Abstract:
The tea geometrid, Ectropis obliqua Prout (Lepidoptera: Geometridae), is a major pest of tea plantation and poses a considerable economic threat to tea industry. We have sequenced the complete mitochondrial genome of E. obliqua. The entire genome is 16,535 bp in length with an A + T content of 81.32% (GenBank accession No. KX827002). The tea geometrid mt genome encodes all 37 genes that are typically found in animal mt genomes, consists of 13 protein-coding genes (PCG), two ribosomal RNA genes, and 22 transfer RNA genes. The gene order is consistent with other sequenced mt genome of moths and butterflies in Ditrysia. The A + T-rich region is 1523 bp long and consisting of the motif 'ATAGA', a 19 bp poly-T stretch, and a tandem repeat sequence with seven 194 bp repeat units. Phylogenetic analysis was performed using 13 PCG with 16 moths showed that E. obliqua clusters with other Geometridae species.
