In Brazil the numbers of malaria are cause for concern, especially in the “Legal Amazon” region, where climatic conditions favor the development of the mosquito transmitter. One of the regions with a high infection rate is the Juruá valley. The breeding of the vectors are not well characterized, as well as species of mosquitoes present in each one. In the present work, five types of breeding-sites: excavations, fish-farm tanks, reservoirs, lagoons and creeks were identified and a total of 10 species of Anopheles collected. The highest abundance was of An. peryassui (31%), An. triannulatus (28.3%) and An. darlingi (22.5%).
