与许多其他热带国家一样，莫桑比克面临着节肢动物传播的病毒（虫媒病毒）疾病的高风险，最近该国北部发生了两次登革热病毒暴发。埃及伊蚊（伊蚊）和伊蚊（伊蚊）等重要病媒物种的发生。除了其他几种森林媒介外，该国还报告了白纹伊蚊（Skuse），这可能表明一些具有公共卫生重要性的虫媒病毒的传播可能涉及多媒介系统。因此，了解现有和新的重要病媒物种的发生和分布，对于制定系统的传播监测和病媒控制方法至关重要。本研究的目的是绘制莫桑比克北部尼亚萨省可能传播与人类和兽医相关的虫媒病毒的蚊子种类的发生和分布情况。2016年4月在莫桑比克北部尼亚萨省拉戈区进行了现场昆虫学调查。对蚊虫孳生场所进行检查，收集未成熟蚊虫，饲养成蚊。利用分类键对成蚊进行形态鉴定。利用解剖的雄性生殖器和基于序列条形码（cox1 mtDNA）基因的分子系统发育分析，证实了黄头伊蚊（Stegomyia）的形态鉴定。共捕获92只成蚊幼虫。其中16只（17.39%）形态鉴定为伊蚊。luteocephalus。其余标本属于伊蚊。埃及伊蚊（n = 4, 4.35%）；全国已知分类群为维塔伊蚊24只（26.09%）、格纳米按蚊1只（1.09%）、雾状库蚊28只（30.43%）、亚单纯库蚊18只（19.57%）、短喙弓形虫1只（1.09%）。雄性生殖器和系统发育分析证实了伊蚊的身份。本研究收集的黄头虫标本。据我们所知，这是第一次检测到伊蚊。莫桑比克境内的黄头虫是黄热病病毒（YFV）、寨卡病毒（ZIKV）和非洲登革热病毒（DENV）的媒介物种。鼓励进一步研究伊蚊的作用。黄头虫在莫桑比克虫媒病毒性疾病传播中的作用。
Mozambique, same as many other tropical countries, is at high risk of arthropod-borne virus (arbovirus) diseases and recently two dengue virus (DENV) outbreaks occurred in the northern part of the country. The occurrence of some important vector species, such as Aedes (Stegomyia) aegypti (Linnaeus) and Ae. (Stg.) albopictus (Skuse), besides several other sylvatic vectors, have been reported in the country, which may indicate that the transmission of some arboviruses of public health importance may involve multiple-vector systems. Therefore, knowing the occurrence and distribution of existing and the new important vectors species, is crucial for devising systematic transmission surveillance and vector control approaches. The aim of this study was to map the occurrence and distribution of mosquito species with potential for transmitting arboviruses of human and veterinary relevance in Niassa Province, Northern Mozambique. Field entomological surveys were undertaken in April 2016 in Lago District, Niassa Province, northern Mozambique. Breeding sites of mosquitoes were inspected and immature stages were collected and reared into adult. Mosquitoes in the adult stages were morphologically identified using taxonomic keys. Morphological identification of Aedes (Stegomyia) luteocephalus (Newstead) were later confirmed using dissected male genitalia and molecular based on the phylogenetic analyses of the sequenced barcode (cox1 mtDNA) gene. A total of 92 mosquito larvae collected developed into adults. Of these, 16 (17.39%) were morphologically identified as Ae. luteocephalus. The remaining specimens belonged to Ae. (Stg.) aegypti (n = 4, 4.35%), Ae. (Aedimorphus) vittatus (n = 24, 26.09%), Anopheles garnhami (n = 1, 1.09%), Culex (Culiciomyia) nebulosus (n = 28, 30.43%), Eretmapodites subsimplicipes (n = 18, 19.57%) and Toxorhynchites brevipalpis (n = 1, 1.09%), taxa already known to the country. Male genitalia and phylogenetic analyses confirmed the identity of Ae. luteocephalus specimens collected in this study. To our knowledge, this is the first detection of Ae. luteocephalus in Mozambican territory, a vector species of yellow fever virus (YFV), Zika virus (ZIKV) and dengue virus (DENV) in Africa. Further studies are encouraged to investigate the role of Ae. luteocephalus in the transmission of arboviral diseases in Mozambique.
