We investigated the historical demography of Anopheles albimanus using mosquitoes from five countries and three different DNA regions, the mitochondrial cytochrome oxidase subunit I gene (COI), the single copy nuclear white gene and the ribosomal internal transcribed spacer two (ITS2). All the molecular markers supported the taxonomic status of a single species of An. albimanus. Furthermore, agreement between the COI and the white genes suggested a scenario of Pleistocene geographic fragmentation (i.e., population contraction) and subsequent range expansion across southern Central America.
我们使用来自五个国家的三种不同 DNA 区域(线粒体细胞色素氧化酶亚基 I 基因(COI)、单拷贝核白基因和核糖体内部转录间隔区 2(ITS2))的蚊子来研究按蚊的历史人口动态。所有的分子标记都支持按蚊的分类地位是一个单一的物种。此外,COI 和白基因之间的一致性表明了更新世地理分裂(即种群收缩)的情景,随后在中美洲南部地区扩展。
