摘要

The Xingu River has a huge hydroelectric potential, specifically in the Volta Grande, where the hydroelectric power station of Belo Monte will be installed. For the implementation of this construction project an environmental impact study was necessary, considering the fauna, flora and the social aspects. In order to perform the faunistic analysis of grasshoppers species in the area of direct influence of the construction project of Belo Monte, an inventory was carried out using entomological nets from November/2007 to August/2008. It was collected 2652 grasshoppers, which belonged to 3 families, 10 subfamilies, 18 tribes, 42 genera and 71 species. The faunistic analysis demonstrated that 74% of the species were classified as rare or minimal and with regard to constancy 54.9% were classified as accidental. The highest levels of diversity and richness of grasshoppers occurred in the area A2 that will be flooded to form the hydroelectric lake, which may cause local extinction of these species
