A diversificacao da propriedade agricola e o uso de sistemas agroflorestais trazem diversos beneficios para o agroecossistema, pela consequente atracao de inimigos naturais e reducao de insetos herbivoros. As formigas constituem um grupo importante de insetos em agroecossistemas. O objetivo com esse trabalho foi analisar a ocorrencia de diferentes guildas de formigas em tres estrategias de restauracao florestal comparadas com uma floresta em estagio avancado de sucessao em um sistema agricola. Para este fim foram realizadas coletas mensais de formigas durante os meses de fevereiro a julho de 2013 em uma propriedade agricola, em diferentes areas de ambientes florestais e agroflorestais. Observou-se com este experimento que as formigas predadoras ocorrem mais frequentemente em areas com vegetacao em estagio sucessional avancado, e que formigas cortadeiras ocorrem mais frequentemente em ambientes de vegetacao em estagio inicial de sucessao. Ant fauna in agroecosystems and their role in agroecological transition. ABSTRACT: The diversification of farm and agroforestry systems bring many benefits to the agroecosystem, the consequent attraction of natural enemies and the decrease of herbivorous insects. The ants are a important group of insects in agroecosystems. The aim of this experiment was to analyze the occurrence of different guilds of ants in three forest restoration strategies compared with a forest in an advanced stage of succession in an agroecosystem. For this purpose, ants were collected monthly during the months from February to July of 2013 on a farm, in different areas of forest and agroforestry environments. It was noted in this experiment that the predatory ants occur more frequently in areas with vegetation successional stage advanced, and that the leaf cutting ants occurred more frequently in environments of vegetation in early stages of succession.
