Phylogenetic relationships among Tsushima Island (highlighted in red) and various other populations of Locusta migratoria. The original tree was constructed by Tokuda et al. (2010) using the neighbor-joining method based on a combined dataset of 2181 bp, including sequences of cytochrome b, cytochrome oxidase subunit I, NADH dehydrogenase subunit II, and 12S ribosomal RNA. Bootstrap values are provided for nodes supported by more than 50% in 1000 pseudoreplicates. This figure has been reproduced with permission and some modifications. For a detailed explanation, see Tokuda et al. (2010).
