The Asian tiger mosquito, Aedes albopictus, is a common mosquito in East and Southeast Asia, but its habitats have expanded to the American, African and Australian continents, Europe and many other areas. Aedes albopictus can transmit some important arboviruses that cause human mortality. To control the global spread of this mosquito, genetic analyses of A. albopictus populations have been undertaken throughout the world. In Japan, however, few attempts have been made to characterize the population structures of these mosquitos. In this study, adult A. albopictus populations were sampled from seven parks in the urban area of Tokyo, and analyses of the mitochondrial cytochrome c oxidase subunit 1 (COI) gene base sequences revealed small genetic variations. Only three haplotypes were identified, and most of the samples belonged to a single haplotype. In addition, despite a developed international trade network, no establishment of A. albopictus populations from multiple origins was found. We also evaluated the genetic diversity outside Tokyo using data from a previous study for comparison and found that the genetic diversity in the urban area of Tokyo was lower than that in Nagasaki City (Japan) and in other countries, including the USA and Italy, where A. albopictus populations from Japan have been established.

日本东京市区的亚洲虎蚊（Aedes albopictus）显示出低的细胞色素C氧化酶亚基1多样性
亚洲虎蚊（Aedes albopictus）是东亚和东南亚的常见蚊子，但其栖息地已扩展到美洲，非洲和澳大利亚大陆，欧洲等许多地区。白纹伊蚊可以传播某些重要的虫媒病毒，导致人类死亡。为了控制这种蚊子的全球传播，已经在世界范围内对白化曲霉种群进行了遗传分析。但是，在日本，很少有人试图描述这些蚊子的种群结构。在这项研究中，从东京市区的七个公园中采样了成年的白线虫种群，并分析了线粒体细胞色素C氧化酶亚基1（COI））基因碱基序列显示出较小的遗传变异。仅鉴定出三种单倍型，并且大多数样品属于单个单倍型。此外，尽管国际贸易网络发达，但仍未发现来自多个起源的白带线虫种群。我们还使用先前研究的数据进行了比较，评估了东京以外地区的遗传多样性，发现东京市区的遗传多样性低于长崎市（日本）和其他国家（包括美国和意大利）已经确定了来自日本的白带菌种群。
