This investigation was conducted to compare the soil ant fauna of an eucalypt plantation to that of a second growth forest; both áreas located in the Zona da Mata of Minas Gerais, Brazil. Tuna fish, honey and cracker baits were used to collect ants along a transect and pitfall traps were distributed in central 900 m of each site. A total of 64 species belonging to 26 genera were collected in the 12 weekly samples; 54 species were captured in the forest and 45 in the Eucalypíus granais plantation. A total of eight species presented frequencies above 10% in at least one area. Species richness was higher in the second growth forest. Additional studies should be considcred for further generalizations of the results.
