(Skuse, 1894), a mosquito originating in Asia, has been introduced to Africa since the 2000s. The mosquito is not only a nuisance but is capable of transmitting various arboviruses. The current study summarized our entomological surveys in the Democratic Republic of Sao Tome and Principe during 2000 to 2016. Adult mosquitoes were collected by sweep nets, human landing catches, and Centers for Disease Control (CDC) light traps, and the immatures were collected from water-filled habitats at 15 sentinel sites and reared to adulthood. Species identification was performed based on morphologic characteristics. Fragments of the cytochrome C oxidase subunit I () and the surface protein () genes were amplified for mosquitoes collected in Principe. New records of four mosquito species were reported. was identified in 2015. The larvae were found distributed over the nation and were predominately in artificial water-holding containers (488/2698, 18.1%). The highest positive rate was observed in used tires in Príncipe (114/250, 45.6%). Mitochondrial DNA analysis revealed low genetic diversity among the invasive populations, but all tested specimens were superinfected by . The ability of to adapt to new environments and its involvement in disease transmission make the surveillance and control of this species particularly important.
源自亚洲的一种蚊子（Skuse，1894年）自21世纪以来已传入非洲。这种蚊子不仅令人讨厌，而且能够传播多种虫媒病毒。当前的研究总结了我们在2000年至2016年期间在圣多美和普林西比民主共和国进行的昆虫学调查。通过扫网、人诱捕和疾病控制中心（CDC）诱蚊灯诱捕收集成年蚊子，并从15个监测点的积水生境中收集幼虫并饲养至成年。根据形态特征进行物种鉴定。对在普林西比收集的蚊子，扩增了细胞色素C氧化酶亚基I（）和表面蛋白（）基因的片段。报告了四种蚊子的新记录。于2015年被鉴定。发现幼虫分布于全国，主要存在于人工蓄水容器中（488/2698，18.1%）。在普林西比的废旧轮胎中观察到最高阳性率（114/250，45.6%）。线粒体DNA分析显示入侵种群的遗传多样性较低，但所有测试标本都被超感染。适应新环境的能力及其在疾病传播中的作用使得对该物种的监测和控制尤为重要。
