The use of different practical vegetal coverings and cultural seems to act directly on soil mesofauna. The objective of this work was to evaluate the variations of the groups of soil mesofauna n different systems of handling of the ground. The treatments had consisted of three areas: castor bean (Ricinus communis L.), pasture (Brachiaria decumbens) and native woods. In each area 21 samples had been removed, seven for treatments, three times. The soil mesofauna extracted using a modified Berlese-Tullgren apparatus. In the evaluation of the ecological behavior ofmesofauna, the total number of individuals was mensured and had been made comparisons of the communities using: the Shannon index and the Pielou index. Pertaining ones to filo Arthropoda had been identified to 13 taxonomics groupsin the three areas in study, being all. In the area and castor bean lesser diversity in the structure of the community of arthropods was verified, evidencing the influence of the culture systems on the population of soil mesofauna, diminishing its density and diversity in relation to the native woods area.
