中文摘要：

本研究通过收集中国的栖北散白蚁Reticulitermes speratus（Kolbe）种类,进行线粒体DNA细胞色素氧化酶Ⅱ（COⅡ）基因扩增测序,将所得序列与日本和韩国的R.speratus COⅡ序列进行比较分析,进而比较东亚地区R.speratus种类的亲缘关系和迁徙路线。结果显示中国与韩国、中国与日本分别存在相同的R.speratus亚种,且R.speratus在东亚地区的最有可能迁徙路线是先从中国迁徙到日本,再从日本传播到韩国。

英文摘要：

In this study,Reticulitermes speratus（ Kolbe） were collected in China and a portion of the mitochondrial gene encoding for the cytochrome oxidase subunit Ⅱ（ COⅡ） was sequenced. In order to compare the phylogenetic relationship and migration route of R. speratus in east Asia,Gen Bank data of Korean populations,southern and northern Japanese populations were used. According to the comparative analysis of the sequences,it was suggested that the same R. speratus subspecies existed in China and Japan,China and Korea,respectively,and R. speratus migrated into the Japanese main islands from east China,and Korean populations diverged from Japanese populations.
