蚊子，特别是埃及伊蚊，正在成为研究入侵生物学的重要模型。我们研究了79个Ae群体中12个微卫星座位的遗传变异。埃及人，来自六大洲的30个国家，并用它们来推断历史和现代的入侵模式。我们的结果支持两个亚种Ae。Aegypti formosus和Ae.埃及伊蚊是遗传上截然不同的单位。天哪。非洲以外的埃及伊蚊种群来源于非洲祖先种群，是单系进化的。这两个亚种同时出现在东非(肯尼亚)和西非(塞内加尔)。在农村/森林环境(肯尼亚的拉拜区)，这两个亚种在遗传上保持不同，而在城市环境中，它们自由地进入。非洲以外的种群具有高度的遗传结构，可能是由于最近的创始人效应、离散的不连续栖息地和低迁移率的组合。撒哈拉以南非洲的祖先种群的基因结构较少，亚洲的种群也是如此。介绍了Ae.埃及人到新大陆的时间与16至18世纪的跨大西洋航运不谋而合，紧随其后的是19世纪末从新大陆或地中海盆地现已灭绝的人口传入亚洲。马斯卡伊蚊是伊蚊的遗传姊妹种。埃及伊蚊..这项研究提供了一个遗传多样性的参考数据库，可以用来确定这种入侵物种经常发生的新引入的可能来源。许多群体和地区的遗传独特性对试图控制Ae具有重要意义。埃及伊蚊，尤其是对种群进行基因改造的方法。
Mosquitoes, especially Aedes aegypti, are becoming important models for studying invasion biology. We characterized genetic variation at 12 microsatellite loci in 79 populations of Ae. aegypti, from 30 countries in six continents and used them to infer historical and modern patterns of invasion. Our results support the two subspecies Ae. aegypti formosus and Ae. aegypti aegypti as genetically distinct units. Ae. aegypti aegypti populations outside Africa are derived from ancestral African populations and are monophyletic. The two subspecies co-occur in both East Africa (Kenya) and West Africa (Senegal). In rural/forest settings (Rabai District of Kenya) the two subspecies remain genetically distinct whereas in urban settings they introgress freely. Populations outside Africa are highly genetically structured likely due to a combination of recent founder effects, discrete discontinuous habitats, and low migration rates. Ancestral populations in sub-Saharan Africa are less genetically structured, as are the populations in Asia. Introduction of Ae. aegypti to the New World coinciding with trans-Atlantic shipping in the 16th to 18th Centuries was followed by its introduction to Asia in the late 19th Century from the New World or from now extinct populations in the Mediterranean Basin. Aedes mascarensis is a genetically distinct sister species to Ae. aegypti s.l.. This study provides a reference database of genetic diversity that can be used to determine the likely origin of new introductions that occur regularly for this invasive species. The genetic uniqueness of many populations and regions has important implications for attempts to control Ae. aegypti, especially for methods using genetic modification of populations.
