M. de  aAnts as bioindicators of the soil quality in agroecologic systems.  c2008  aThe 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.1 aAQUINO, A.
