What does this research mean for the field?

Aedes albopictus exhibits low global genetic variation due to recent human-mediated spread, whereas South American Aedes aegypti populations largely derive from South-East Asia, with the exception of a relict African lineage in northern Amazonia that likely persisted since the slave trade.

Abstract

埃及伊蚊 (Stegomyia) aegypti (L.) 和白纹伊蚊 (Stegomyia) albopictus (Skuse) 是登革热和黄热病毒最重要的传播媒介。它们都利用贸易发展从原产地传播到热带地区：A. aegypti 起源于非洲，A. albopictus 起源于东南亚。我们基于三种线粒体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 A. aegypti 与 A. albopictus 蚊子的关系。A. albopictus 的遗传变异很小，可能是由于该物种最近通过人类活动传播。A. aegypti 的大多数南美种群与东南亚（泰国和越南）种群在遗传上相似，只有来自博阿维斯塔（北亚马逊）的一个样本与非洲（几内亚和科特迪瓦）的样本关系更近。这表明，奴隶贸易期间引入的非洲 A. aegypti 种群在博阿维斯塔生存下来，并抵抗了消灭措施的影响.
