The aim of this work was to monitory and control of the immature mosquitoes around Dona Francisca Hydroelectric (DFH), Agudo, RS. There was a great concern to avoid the introducing of human diseases vectors in this place. Six areas were selected for sampling larva: The hotel swimming pool, the clubhouse near Jacui river, the station of water treatment, the administration square, workers lodgings and tyre fixing places. The collections were taken at three months intervals, during the building period of DFH (June/2000 to February/2001). Lectures were provided for about three thousand people in schools near DFH. No important epidemic species was found, only Aedes fluviatilis and other species of genus Culex, Limatus, and Orthopodomyia. The numbers of artificial breeding places and captured immature mosquitoes decreased throughout the study. There was not significant correlation between the number of mosquitoes captured and the environment factors (temperature, precipitation, and air relative humidity) probably due to the control and decreasing in artificial breeding places.
