Aedes (Stegomyia) aegypti (l.) and Aedes (Stegomyia) albopictus (Skuse) are the most important vectors of the dengue and yellow-fever viruses. Both took advantage of trade developments to spread throughout the tropics from their native area: A. aegypti originated from Africa and a. albopictus from South-East Asia. We investigated the relationships between A. aegypti and A. albopictus mosquitoes based on three mitochondrial-DNA genes (cytochrome b, cytochrome oxidase I and NADH dehydrogenase subunit 5). Little genetic variation was observed for a. albopictus, probably owing to the recent spreading of the species via human activities. For A. aegypti, most populations from South America were found to be genetically similar to populations from South-East Asia (Thailand and Vietnam), except for one sample from Boa Vista (northern Amazonia), which was more closely related to samples from Africa (Guinea and Ivory Coast). This suggests that African populations of A. aegypti introduced during the slave trade have persisted in Boa Vista, resisting eradication campaigns.
埃及伊蚊（白纹伊蚊亚属）和白纹伊蚊（白纹伊蚊亚属）是登革热病毒和黄热病病毒最重要的传播媒介。它们都利用贸易发展从原生地传播到整个热带地区：埃及伊蚊起源于非洲，白纹伊蚊起源于东南亚。我们基于三个线粒体DNA基因（细胞色素b、细胞色素氧化酶I和NADH脱氢酶亚基5）研究了埃及伊蚊和白纹伊蚊之间的关系。白纹伊蚊的遗传变异很少，这可能是由于该物种最近通过人类活动传播所致。对于埃及伊蚊，除了来自博阿维斯塔（亚马孙河以北地区）的一个样本与来自非洲（几内亚和科特迪瓦）的样本关系更密切外，南美洲的大多数种群在基因上与来自东南亚（泰国和越南）的种群相似。这表明在奴隶贸易期间引入的非洲埃及伊蚊种群在博阿维斯塔持续存在，抵抗了根除行动。
