Introduction: Aedes fluviatilis(Lutz, 1904) is considered a potential vector of yellow fever and dengue viruses and is naturally infected by Wolbachia.
Methods: In March 2018, during a field activity in the municipality of Saboeiro, 163 mosquito larvae were collected in a dammed area of the Jaguaribe River.
Results: Of the larvae collected, 143 (87.7%) were identified asAe. fluviatilis.
Conclusions: We report the first documentation of Ae. fluviatilis in the municipality of Saboeiro, northeastern Brazil. It is important to conduct additional entomological surveys to characterize the local Culicidae fauna. Ignoring the presence and dispersion of this vector could be a public health risk.
