- Abstract
The immense sampling effort used in ecological research on dung beetles (Coleoptera: Scarabaeidae: Scarabaeinae) has required large amounts of human feces to conduct experiments in the field. Thus, the amount of human feces available can be an important limiting factor for research. Therefore, dung from large omnivorous mammals, such as pig, has been used to reduce this limitation. Here, we evaluated how the type of diet can influence the attractiveness of omnivorous-mammal feces to Amazonian dung beetles. We sampled dung beetles in 10 fragments of Amazon rainforest in July 2018 (dry season) and March 2019 (rainy season), using pitfall traps baited with swill pig dung (household waste-based diet), grain pig dung (maize soybean-based diet), and human feces (control) in Juína, Mato Grosso, Brazil. In all, 2,080 individuals from 51 species of dung beetles were collected. Between the pig dung evaluated, higher total abundance and species richness was captured with grain pig dung. However, the species composition and community structure were similar between pig dung types. Additionally, grain pig dung captured total species richness, species composition, and structure similar to that for human feces. Thus, although grain pig dung did not sample total abundance similar to human feces, this type of dung can be efficient for an accurate survey of the total species richness, species composition, and structure of dung beetles in the Amazon rainforest.
