We present a population genetic study of Aedes aegypti in Brazil using isoenzyme markers. Four polymorphic loci were used to examine 11 mosquito collections at four periods in 2003. Samples from a dengue-endemic area (southeastern region) and a dengue-free area (southern region) connected by an important network of roads and railways were analyzed. The degree of genetic differentiation observed between populations is consistent with limited gene flow between them. There was no evidence of passive dispersion of Ae. aegypti by vehicles among the different routes linking metropolitan areas.
我们利用同工酶标记对巴西的埃及伊蚊进行了群体遗传学研究。2003年，我们在四个时间段使用四个多态性位点对11个蚊虫样本进行了检测。我们分析了来自登革热流行地区（东南部地区）和登革热非流行地区（南部地区）的样本，这两个地区通过重要的公路和铁路网络相连。观察到的种群间遗传分化程度与它们之间有限的基因流动一致。没有证据表明埃及伊蚊通过车辆在连接大都市地区的不同路线之间进行被动扩散。
