Urutaú Natural Reserve is a protected area located in the south of Misiones province, Argentina, near Posadas Capital. This location is characterized by warm and humid climate that promote great flora and fauna diversity. Regarding the mosquito fauna, from 194 species recorded for Misiones province, 66 species are actually registered for Candelaria and 88 for Capital Department. It is known that many of them are vectors of pathogens and parasites that cause human and animal diseases. Our goal was to know the mosquito community in order to consider their importance in pathogens and parasites transmission and evaluate the performance of different capturing techniques. The study was performed between September 2018 and May 2019 through four surveys. We sampled both, adults and immature stages using light traps (CDC and Fabric trap) at night and nets with aspirators (Net/Asp) during the day. Immature stages were collected from different water bodies under the ground, foliar axils and tree holes. A total of 2541 adults and 24 immature individuals were collected. Comparing the number of species and the number of individuals captured as adult with different methodologies, Net/Asp was the most effective in capturing diversity of species while CDC captured significantly higher number of individuals but with lower diversity (P
