Resumo: OBJECTIVE: To describe the culicidae fauna in an area impacted by environmental changes caused by the construction of a dam. METHODS: The studied area was the Porto Primavera dam construction site in Southeastern Brazil. Monthly culicidae samples were taken in six exploratory sites in the pre-filling period and in one fi xed site, one year before (1997-1998) and after the first filling (1999-2000). Adult mosquitoes were captured in the morning with an aspirator and with Shannon and CDC traps during the evening twilight period. Immature stages were captured using a ladle in the larger breeding sites and with a pipette in the smaller ones. RESULTS: In the pre-filling period of the dam, a total of 944 immature culicidae specimens, from ten species, were captured. A total of 14,932 adults were captured, including 7,031 mosquitoes from ten species in the exploratory points and 7,901 specimens from eight genera in the fixed site. After the first stage of the dam filling, the immature stages total was 1,201, from four genera, and the captured mosquitoes total was 5,912, from nine genera. There was a population reduction of the genera Aedes and Psorophora and an increase of the following species populations: Aedeomyia, Anopheles, Culex (Melanoconion), Mansonia and Uranotaenia. CONCLUSIONS: The environmental changes caused due to the construction of the Porto Primavera Dam contributed to an increase in the population density of some culicidae vectors, causing a nuisance and the potential risk of the transmission of pathogens to humans.

OBJETIVO: Descrever a fauna Culicidae em área sob impacto da modificação ambiental causada pela construção de represa. MÉTODOS: Foi estudada a área onde estava sendo construída a Represa Porto Primavera no município de Presidente Epitácio, SP. As capturas dos culicídeos foram realizadas mensalmente, em seis pontos exploratórios antes do seu enchimento e em um ponto fixo, um ano antes (1997-1998) e outro depois do primeiro enchimento (1999-2000). Mosquitos adultos foram capturados com aspirador, no período matutino, e com armadilhas de Shannon e CDC, no período crepuscular vespertino. Os imaturos foram coletados por meio de conchadas nos criadouros maiores e com pipeta, nos menores. RESULTADOS: No período anterior ao enchimento da represa foram coletados 944 exemplares de culicídeos imaturos, distribuídos em dez gêneros. O total de adultos foi de 14.932, dos quais 7.031 mosquitos (em dez gêneros) foram capturados nos pontos exploratórios e 7.901 espécimes, distribuídos em oito gêneros, no ponto fixo. Após a primeira etapa de enchimento da represa, o total de imaturos foi de 1.201 exemplares, distribuídos em quatro gêneros, e o total de mosquitos capturados foi de 5.912, distribuídos em nove gêneros. Houve redução populacional de espécies dos gêneros Aedes e Psorophora e aumento no número de espécimes dos gêneros Aedeomyia, Anopheles, Culex (Melanoconion), Mansonia e Uranotaenia. CONCLUSÕES: As mudanças ambientais decorrentes da construção da Represa Porto Primavera favoreceram o aumento da densidade de algumas populações de culicídeos vetores e que geram incômodo, com riscos potenciais de transmissão de patógenos para humanos.
