Estudo do impacto da construção de duas barragens na dinâmica populacional de mosquitos (Diptera: Culicidae) na região metropolitana de São Paulo

Abstract

Like any enterprise that locally modify the water regime, the construction of dams supply modifies the ecology of Culicidae, which may lead to the emergence of epidemic outbreaks. In the present study was studied and compared as was the response of this community in the construction of dams and Paratirinda Bitiriba-Mirim, between 2002 and Both are part of the Alto Tiete System Producer, responsible for supplying most of metropolitan Sao Paulo. Sampling took place at Shannon trapping method, based on data collected were calculated index of ecological components, such as wealth, constancy, abundance, similarity, and others.The analysis of these components revealed that the faunas of the two dams had different stages, soon had the impact difererentes reactions. In Biritiba Mirim was present a wildlife forestry, which greatly diminished with the flood, while the fauna associated with macrophytes and temporary breeding sites grew, this led to decreased diversity in the period studied. In forestry Paraitinga fauna was absent, so the modifications were minor qualitative and quantitative. We have found the
