Summary

As comunidades da fauna edáfica refletem claramente diferenças na vegetação e práticas de manejo. Esta pesquisa teve o objetivo de avaliar a abundância e equidade da macro e mesofauna do solo frente ao tipo de manejo agrícola em áreas de plantio de café sob três tipos de manejo: sistema convencional – CONV, agroecológico – AGRO, agroflorestal – SAF, avaliados em duas épocas de coleta. Para a avaliação da macro e a mesofauna edáfica hipogéica, foram coletados blocos de solo de 20 x 20 x 10 cm, sendo coletado, primeiramente, todo o resíduo vegetal sobre a superfície do solo. O solo e a serapilheira foram colocados em funis de Berlese por sete dias, e os pitfalls instaladas no campo por 72 horas. Mensurou-se a abundância, riqueza, diversidade dos animais do solo e os grupos funcionais. Por fim, conclui-se que as épocas de coleta influenciaram a abundância de fauna, riqueza e diversidade de grupos; os grupos da fauna edáfica coletados estiveram presentes em todos os sistemas de manejo com café, a exceção do grupo Opilionida; nos pittfalls a riqueza foi maior a do solo e da serapilheira; os grupos formicidae e micrófagos foram os dominantes nos agroecossitemas avaliados.

Summary translation

The edaphic faunal contributes to the decomposition of organic matter and soil structure, so their identification and quantification are essential to understand the biological interactions of the soil/plant. The edaphic faunal communities clearly reflect differences in vegetation and management practices. This research aimed to evaluate the abundance and fairness of the macro and mesofaunal of the soil against the type of agricultural management in coffee growing areas in three types of management: conventional system, CONV, agroecology, AGRO, agroforestry, SAF, and forest, MATA, next to each management system, valued at two times of collection. For the evaluation of macro and mesofaunal hypogeum edaphic, were collected all the litter on the soil surface and soil blocks from 20 x 20 x 10 cm. Soil and litter were placed in Berlese funnels for seven days, and pitfalls traps installed in the field for 72 hours. The variables were the abundance, richness, diversity and soil animal functional groups. The collection periods influenced the abundance of wildlife richness and diversity of groups. The groups collected edaphic faunal are present in all management systems with coffee, except for the group Opiliones. Traps pitfalls wealth was greater than that of soil and leaf litter. The groups were Formicidae and microphagous dominant in agroecossitems evaluated in both samplings.
