Entomological investigations of the possible mosquito vectors of the yellow fever epidemic on the Jos Plateau, Nigeria, were carried out between 27 October and 15 November 1969.Of the 5 species of Aedes (Stegomyia) collected, Ae. luteocephalus was the most abundant in human-bait captures. Ae. aegypti, Ae. africanus, and Ae. vittatus were collected in low numbers. The aegypti larval index in the areas investigated was very low and the species was not considered to be the primary vector in the epidemic. Ae. simpsoni larvae were abundant, but no adults were collected on human bait.Six isolates of 5 different arboviruses were obtained: yellow fever from damaged Stegomyia sp.; dengue 2 from damaged specimens, probably all Ae. luteocephalus; Zika (2 isolates) from Ae. luteocephalus; Bwamba from Anopheles funestus; and a Nyando-group virus from An. gambiae.
1969年10月27日至11月15日期间，在尼日利亚乔斯高原对黄热病疫情可能的蚊媒进行了昆虫学调查。在采集到的5种伊蚊（埃及伊蚊亚属）中，黄头伊蚊在人饵诱捕中数量最多。埃及伊蚊、非洲伊蚊和条斑伊蚊的捕获数量较少。在所调查地区，埃及伊蚊幼虫指数非常低，该物种不被认为是疫情的主要传播媒介。辛普森伊蚊幼虫数量很多，但在人饵诱捕中未采集到成虫。获得了5种不同虫媒病毒的6个分离株：从受损的埃及伊蚊亚属物种中分离出黄热病病毒；从受损标本中分离出登革热2型病毒，可能均来自黄头伊蚊；从黄头伊蚊中分离出寨卡病毒（2个分离株）；从恶疟按蚊中分离出布瓦姆巴病毒；从冈比亚按蚊中分离出一种尼安多病毒群病毒。
