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 …
