Biological invasions have critical impacts on native biodiversity and human societies and especially on oceanic islands that are fragile and threatened ecosystems. The invasive tiger mosquito Aedes (Stegomyia) albopictus (Skuse, 1894) native to Southeast Asia has been introduced during the past 30 years almost everywhere in the world, including the Americas, the Pacific, Europe and Africa. It has been reported for the first time in the Gulf of Guinea in 2000, first in Cameroon, then in Bioko Island in 2003 and more recently in Gabon in 2007. Here we report the first record of Ae. albopictus on São Tomé Island. Although we cannot estimate precisely the year of introduction on São Tomé Island, it most likely arrived within the last 10 years. By sequencing the mitochondrial cytochrome c oxidase gene from individual adults, we detected three haplotypes already present in mainland Africa. More studies are needed to explore the dynamics of its expansion and competition with insular native mosquitoes.
生物入侵对本地生物多样性和人类社会有着至关重要的影响，对脆弱且受到威胁的海洋岛屿生态系统影响尤甚。原产于东南亚的入侵性白纹伊蚊（学名：埃及伊蚊白纹亚种，斯基斯，1894年）在过去30年里几乎被引入到了世界各个地方，包括美洲、太平洋地区、欧洲和非洲。2000年在几内亚湾首次有相关报道，先是在喀麦隆，然后于2003年在比奥科岛，最近在2007年在加蓬也有发现。在此，我们报告白纹伊蚊在圣多美岛的首次记录。尽管我们无法精确估计其被引入圣多美岛的年份，但很可能是在过去10年内到达的。通过对单个成年个体的线粒体细胞色素c氧化酶基因进行测序，我们检测到了在非洲大陆已经存在的三种单倍型。需要开展更多研究来探索其扩张动态以及与岛屿本地蚊子的竞争情况。
