The conventional agriculture production uses chemical products, tillage and other technics harmful
to the soil and health the living beings. Because of that grown producers have been looking for
alternative approaches of production. Otherwise, there are few studies about monitoring of soil
quality, which may subsidize the management of natural resources in agroecologic systems.
This work aimed to the evaluate of the soil quality in agroecossystems, using ants as ecologic
bioindicators. Ants has big potential as bioindicators because they are insects with high
geographical distribution, easy sampling and sensitive to environmental changes. Samples were
collected on four rural properties localize in three municipalities of the state of Paraná (Rio Azul,
Porto Vitória e Biturana), Brazil using the TSBF method (ANDERSON & INGRAM, 1993) with
parcels of 25 x 25cm and 0-10, 10-20 and 20-30cm depth, with five replicates per area. The soil
of three areas were evaluated: corn monoculture, corn intercropped with green manure and
forest area near the cultivated areas. In all properties, the forest area had diversity index and
species richness of ants higher than the cultivated areas. This aspect is important in agroecologic
systems, because the forest areas act as ?hot spot? of the species. In Biturana the forest area
had the highest species diversity of ants, indicating to be more conservated than in the other
municipalities. Although the distribution of the species did not clearly presented a standard in
relation to the use of green manure, probably as a result of the short time of use, some phenomena
were observed that better need to be investigated. MenosThe conventional agriculture production uses chemical products, tillage and other technics harmful
