A survey of restriction fragment polymorphism in mitochondrial DNA (mtDNA) of 17 populations of the mosquito Aedes albopictus was undertaken. The mtDNA size was estimated to be about 17.5 kbp. The level of polymorphism was low, with over 99% of the fragments being shared in common among the 17 populations. Three populations, Mauritius, Singapore, and Hong Kong, contained individuals with both the ancestral and novel mtDNA haplotypes. We conclude that the low level of mtDNA polymorphism in A. albopictus is a result of recent range expansion and that the mixture of haplotypes is a likely result of human-aided gene flow among populations.
对17个白纹伊蚊种群的线粒体DNA(mtDNA)限制性片段多态性进行了调查。估计mtDNA大小约为17.5千碱基对。多态性水平较低,17个种群中超过99%的片段是共有的。毛里求斯、新加坡和香港这三个种群中既有祖传的mtDNA单倍型个体,也有新的mtDNA单倍型个体。我们得出结论,白纹伊蚊mtDNA多态性水平较低是近期分布范围扩张的结果,单倍型的混合可能是种群间人为辅助基因流动的结果。
