This study evaluated the Scarabaeinae beetle community in pastures with varying levels of degradation in the municipality of Itaituba, Pará, Brazil. Sampling was conducted in 20 distinct areas during both dry and rainy seasons, using pitfall traps baited with dung, meat, banana, and a control. A total of 2,478 individuals were collected, representing 33 species and nine genera. The rainy season showed significantly higher abundance and species richness compared to the dry season. Dung was the most effective bait in terms of abundance and richness. NMDS and PERMANOVA analyses revealed significant differences in species composition between seasons, but not among bait types. Abundance was negatively influenced by fire and positively associated with soil moisture, and proximity to water sources and cattle corrals. Species richness was positively correlated with the proximity and size of forest fragments, and negatively with soil compaction. The findings indicate that even in anthropized environments, micro-scale environmental variables significantly affect the structure of Scarabaeinae communities. The study highlights the importance of sustainable management practices, such as forest fragment conservation and fire control, for maintaining local biodiversity.
