ABSTRACT:     The soil fauna is one of the bioindicators of soil quality that has greater sensitivity, being easily altered by changes that occur in natural and agricultural ecosystems. The objective of this work was to evaluate the density and diversity of the soil macrofauna and the functional groups of the epigeal macrofauna that are most representative in no-tillage, pasture, eucalyptus cultivation  and  native  savanna  systems  in  Uruçuí,  Piauí,  Brazil.  Five  soil  management  systems  were  used:  pasture  (PAS);  no  tillage soybean in corn straw (NT1); no tillage of corn under straw of mombaça grass (NT2); eucalyptus (EUC), in addition to a savanna  area  used  as  a  reference  (FA).  Fauna  collection  was  performed  using  pitfall  traps  containing  4%  formaldehyde.  The  fauna  was  evaluated  by  the  number  of  individuals  per  trap  per  day,  wealth,  average  wealth,  Shannon’s  diversity  index  and  Pielou’s uniformity index. The data was subjected to analysis of variance, and when significant, was subjected to the Friedman test. The pasture system had the least impact on edaphic fauna when compared to native savanna forest and when compared to management systems and the collembola, orthoptera and diptera groups were the most abundant in the studied management systems.

RESUMO:       A  fauna  do  solo  é  um  dos  bioindicadores  da  qualidade  do  solo  que  possui  maior  sensibilidade,  sendo  facilmente  alterada por mudanças que ocorrem nos ecossistemas naturais e agrícolas. O trabalho teve como objetivo avaliar a densidade e diversidade da macrofauna do solo e os grupos funcionais da macrofauna epígea mais representativos em sistemas de plantio direto, pastagem, cultivo de eucalipto e Cerrado nativo em Uruçuí, Piauí, Brasil. Foram utilizados cinco sistemas de manejo do solo: (i) pastagem (PAS); (ii) plantio direto de soja sob palhada de milho (SPD1); (iii) plantio direto de milho sob palhada de capim mombaça (SPD2); (iv) eucalipto (EUC), além de (v) uma área de Cerrado usada como referência (MN). Foi realizada coleta da fauna, por meio de armadilhas do tipo pitfall contendo 4% de formol. A fauna foi avaliada pelo número de indivíduos por armadilha dia, riqueza, riqueza média, índice de diversidade de Shannon e índice de uniformidade de Pielou. Os dados foram submetidos à análise de variância, e quando significativo, foram submetidos ao teste de Friedman. Os grupos aranae, blattodea, scorpionidae e  thisanura  foram  drasticamente  afetados  pelos  sistemas  de  manejo  utilizados  em  relação  à  condição  natural.  O  sistema  de  pastagem foi o que apresentou menor impacto sobre a fauna edáfica quando comparado a mata nativa de cerrado.
