An overwintering population of has been documented in the Capitol Hill neighborhood of Washington, DC, since 2011. Mitochondrial cytochrome oxidase I () sequence data presented in a previous study traced the origin to the New World. Here, we use microsatellite and 14,071 single nucleotide polymorphisms along with mitochondrial DNA (mtDNA) sequences on Washington samples and samples from potential sources to further narrow the origin of this population. Genetically, Washington are closest to populations in Florida, meaning this is the most likely source. Florida experienced the first mosquito-borne transmission of dengue in the United States after decades of absence of this disease, as well as local transmission of chikungunya and Zika in recent years. This suggests that the Capitol Hill, Washington, DC population of is capable of transmitting viruses such as dengue, chikungunya, and Zika in modern US city environments.
自 2011 年以来,华盛顿特区国会山地区已经记录到了一种越冬种群。先前的一项研究中提出的线粒体细胞色素氧化酶 I(COI)序列数据表明其起源于新世界。在这里,我们使用微卫星和 14071 个单核苷酸多态性以及华盛顿州蚊子样本和潜在来源样本的线粒体 DNA(mtDNA)序列,进一步缩小了该种群的起源范围。从基因上讲,华盛顿州的蚊子与佛罗里达州的蚊子种群最为接近,这意味着佛罗里达州最有可能是其来源地。佛罗里达州在数十年没有这种疾病之后,首次发生了蚊媒传播的登革热,近年来还发生了基孔肯雅热和寨卡病毒的本地传播。这表明,华盛顿特区国会山地区的这种蚊子能够在现代美国城市环境中传播登革热、基孔肯雅热和寨卡病毒等病毒。
