From September 1998 to September 1999, four censuses were carried out to get information about the number of colonies of paper wasps, their float and kind of substratum used in the campus of Universidade Federal de Juiz de Fora, in Juiz de Fora town, MG. Five genus were found in the campus: 65,25% belongs to Mischocyttarus genus, 23,72% to Polistes, 7,73% to Protopolybia, 3,13% to Polybia and 0,17% to Protonectarina, with an average of 287,75 active colonies. The number of waspss colonies was more abundant during the hot and damps seasons (From September 1998 till the middle of March 1999), suffering a big reduction during the cold and dry season (April 1999 to September 1999). Mischocyttarus, Polistes and Polybia demonstrated a higher level of synanthropy than Protopolybia and Protonectarina, that presented foundations only on vegetation. Polybia presented a great reduction in the number of colonies, due mainly to anthropic action and parasitic infestation by Tachinidae.
