Molecular barcoding and phylogenetic analysis of Monochamus species (Coleoptera: Cerambycidae)

Monochamus species damage conifer trees. Some of them have further economic significance as vectors of the pinewood nematode, which causes pine wilt disease. Some species of Monochamus are difficult to distinguish using morphology. The cytochrome oxidase subunit I gene (COI) of mitochondrial DNA is usually taken as a good marker for species identification. We sequenced the full COI gene of 80 specimens belonging to seven species of Monochamus. We then examine the phylogenetic relationships among these species.
