Aedes vittatus Bigot is distributed throughout Africa, tropical Asia, and southern Europe and occurs in sylvatic as well as peridomestic environments where it readily feeds on humans. Although the vectorial capacity of Ae. vittatus is not well understood, this species is known to play a role in the maintenance and transmission of yellow fever, Zika, chikungunya, and dengue virus within its native range. In October 2019, after a routine inspection of mosquito-breeding containers in Jarabacoa, Dominican Republic, two Ae. vittatus females were captured via human landing catch method. After this finding, a CDC miniature light trap was deployed at the point of initial detection from 18:00 to 08:00 h, 2 d/wk from 3 to 31 October 2019. Potential larval habitats were also sampled via traditional dip method once per week spanning a 150 m radius from point of initial detection. In addition to the 2 adult females, 10 female and 2 male Ae. vittatus were captured. One Ae. vittatus larva also was found in a small puddle formed by an animal hoof print. Conventional PCR and Sanger sequencing were used to confirm morphological identification of collected specimens. This is the first detection of Ae. vittatus in the Dominican Republic as well as the Americas. Therefore, enhanced surveillance is needed to better understand the range and public health risks this potential invasive mosquito species may pose in the Dominican Republic, other Caribbean Islands, and/or the Americas.
