Entomofauna epigeica no conjunto serrapilheira-solo como bioindicadora de manejo em sistemas agrícolas e variações climáticas

Abstract

The epigeic invertebrate entomofauna is highly sensitive to management practices and climatic conditions, serving as bioindicators of soil quality. This study aimed to analyze the dynamics of epigeic entomofauna across different agricultural systems and environmental variations. Sampling was conducted using pitfall traps in five systems: a) agroforestry system, b) native fruit species consortium, c) passion fruit orchard, d) moringa cultivation, and e) a reference forest fragment, during two seasons: autumn and summer. The collected organisms were classified into taxonomic groups (Order, Class, or Family) and analyzed for relative frequency, abundance, richness, litter accumulation, and ecological indices, including Shannon-Weaver (H') and Pielou (e). A total of 3,049 and 3,789 organisms were captured in autumn and summer, respectively. Litter volume was higher in summer, particularly in agroforestry and moringa systems, suggesting enhanced soil quality through increased organic matter and habitat provision. Collembola and Formicidae were the dominant groups in autumn, with Formicidae prevailing across all systems in summer. The highest Shannon-Weaver diversity indices (H') were recorded in the moringa system during summer, followed by the native species consortium. The findings highlight that epigeic invertebrates are effective bioindicators, demonstrating the sustainability and soil quality of these agroecosystems.
