Stream ecosystems may be strongly influenced in different ways by land use. The effects of land-cover patterns on Odonata community were studied in eight streams and seven lakes-dams of northeastern São Paulo State. The pattern analyzed was monoculture (sugar cane) vs. nature reserve in terms of Odonata species richness and similarity. Eighty-five Odonata species were sampled. The species richness was higher in the monoculture (33 species) than nature reserve (30 species) and 22 species were common to both areas. There was not verified relationship between land use and physical or chemical characteristics of the streams or lakes-dams water. These results suggest that some Odonata species are benefited and other affected by anthropogenic actions, although more studies are necessary to evaluate this hypothesis. There were ten new records for São Paulo State (Neoneura sylvatica, Coryphaeschna adnexa, Erythemis haematogastra, E. mithroides, Micrathyria longifasciata, M. pseudeximia, Planiplax machadoi, Lauromacromia sp., Tibiagomphus sp. and Aeschnosoma sp.).
