This research reports the data on nine ground beetle families and their trophic groups surveyed, in the municipality of Laranjeiras (10º48'23"S and 37º10'12"O), Sergipe. Specifically where investigated the family beetle richness and abundance in managed and restoring environments; characterize their trophic groups among the phytofisionomies; and infer about the environmental conditions in the sites. This work deals with data on nine Coleoptera families collected from January to September 2008 using pitfall traps, in four agroecosystems named Atlantic forest fragment (FMT), 1-year reforesting system (ZRI) and 2-year reforesting system (ZR II) and grazing (PST). Dominance, richness, abundance, diversity and equitability indices were analyzed at family level. According to richness, the agroecosystems can be ranked as PST and ZR II (both with seven families), ZR I (with six families) and FMT (with five families). However, the sites strongly superpose in relation to family composition. When it comes to morph-species number the sequence of areas in decreasing order was: FMT, ZR I, ZR II and PST. The greatest abundance was found at FMT representing nearly twice the number of the others and, among these, the grazing area was the less abundant. The pattern of richness and abundance found are influenced by community structure, which was clearly structured by Scarabaeidae dominance in FMT. For this survey, pitfall location at the forest fragment edge may have influenced on the richness sampled. The richest and most abundant family was Scarabaeidae with 51 morph-species and 431 individuals, and was dominant at all sites. The diversity indices for the agroecosystems studied, allow us grouping them as follow: ZRII, PST, ZR I e FMT. Consequently, equitability presented inversed tendency, so can be grouped in the following order ZR II, ZR I, PST and FMT. Despite of that, family abundance was equitativelly distributed for all sites, leading to higher diversity, except for FMT. Family level analyses allow making important inferences about ground beetles, and are useful to evaluate environmental quality. The data suggest that reforesting areas are more similar to grazing area than to forest fragment, considering the pattern of abundance and richness of the analyzed Coleoptera families. So, ground beetle can indicate environmental quality, especially Scarabaeidae since abundance pattern was sensible to environmental conditions.
