The epidemic of Zika in the Western hemisphere has led to intense investigations of all species important in the transmission of Zika virus (ZikV), including putative mosquito vectors. Although evidence points to Stegomyia (= Aedes) (Diptera: Culicidae) mosquitoes as the primary vectors in nature among humans, there remains the possibility that other common mosquito species may be implicated in the rapid spread of the virus. Herein, field-caught Culex quinquefasciatus (Diptera: Culicidae) collected during June 2016 in different neighbourhoods in San Juan, Puerto Rico were examined for the presence of natural infection with ZikV. Stegomyia aegypti (= Aedes aegypti) from the same locations were also analysed. None of the Cx. quinquefasciatus tested showed natural infection for ZikV, whereas S. aegypti tested positive at seven sites. The present results suggest that Cx. quinquefasciatus was not involved in the transmission of ZikV in San Juan, Puerto Rico in 2016.
西半球的寨卡疫情引发了对寨卡病毒（ZikV）传播过程中所有重要物种的深入调查，包括假定的蚊媒。尽管有证据表明埃及伊蚊（=白纹伊蚊）（双翅目：蚊科）是人类中寨卡病毒在自然界的主要传播媒介，但其他常见蚊种仍有可能参与了该病毒的快速传播。在此，对2016年6月在波多黎各圣胡安不同街区野外捕获的致倦库蚊（双翅目：蚊科）进行了检测，以确定其是否自然感染寨卡病毒。同时也分析了来自相同地点的埃及伊蚊（=白纹伊蚊）。所有检测的致倦库蚊均未显示自然感染寨卡病毒，而埃及伊蚊在7个地点检测呈阳性。目前的结果表明，2016年在波多黎各圣胡安，致倦库蚊未参与寨卡病毒的传播。
