Abstract
Abstract The objective of this study was to evaluate the capacity as bioindicators of litter arthropodofauna in pasture restoration in the Atlantic Forest Biome. Areas of native forest under natural regeneration, and pastures treated with different ecological restoration techniques were evaluated, with pitfall traps. The sampling period was from April/2017 to October/2018, bimonthly. Families Ptiliidae, Staphylinidae, and Leiodidae, species Pheidole cf. sarcina (Formicidae) and Mastigoceras sp. 1 and Szeptyckitheca sp. 1 (Collembola) were indicators of well-conserved areas, whereas families Cicadellidae and Delphacidae, Formicidae species Wasmannia auropunctata (Roger, 1863) and Camponotus melanoticus Emery, 1894 were indicators of degraded areas. From the springtail community, species richness is a metric that can be used as a bioindicator. It was observed that all taxonomic identification levels allowed for the differentiation of the environmental conditions of the sampling areas, with less specific identification levels, such as family, possibly indicating changes in areas under the restoration process.

Summary
Insects constitute the most diverse faunal group (Lewinsohn & Prado, 2005) and are involved in almost all ecological processes that occur in ecosystems (Lavelle et al, 2006) They are notable for being one of the main groups providing ecosystem services, directly or indirectly benefiting humans through regulation, provision, support, and cultural services (Schowalter et al, 2018; Dangles & Casas, 2019). Within this group, the ants (Hymenoptera: Formicidae) are an exceptional group because of their abundance, diversity, and functional importance, and are known as ecosystem engineers (Jones et al, 1994). There are negative changes in the community of insect fauna (Bourg et al, 2016; Salomão et al, 2018), ant fauna (Silva et al, 2007), and springtail fauna (Rusek, 1998; Zeppelini et al, 2009)
