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.

亚马逊蜣螂（鞘翅目：金龟科：金龟科）对杂食性哺乳动物粪便的吸引力取决于它们的饮食：对生态监测的影响

蜣螂（鞘翅目：金龟子科：金龟子科）生态研究中使用的大量采样工作需要大量人类粪便进行实地实验。因此，可用的人类粪便量可能是研究的重要限制因素。因此，来自大型杂食性哺乳动物（例如猪）的粪便已被用于减少这种限制。在这里，我们评估了饮食类型如何影响杂食性哺乳动物粪便对亚马逊蜣螂的吸引力。我们在 2018 年 7 月（旱季）和 2019 年 3 月（雨季）在亚马逊雨林的 10 个碎片中采样了蜣螂，使用以泔水猪粪（家庭垃圾为基础的饮食）、谷物猪粪（以玉米+大豆为基础的饮食）作为诱饵的陷阱饮食）和巴西马托格罗索州 Juína 的人类粪便（对照）。一共 2, 收集了来自 51 种蜣螂的 080 只个体。在评估的猪粪之间，谷物猪粪捕获了更高的总丰度和物种丰富度。然而，猪粪类型之间的物种组成和群落结构相似。此外，谷物猪粪捕获的总物种丰富度、物种组成和结构与人类粪便相似。因此，虽然谷物猪粪没有采样与人类粪便相似的总丰度，但这种类型的粪便可以有效地准确调查亚马逊雨林中蜣螂的总物种丰富度、物种组成和结构。猪粪类型之间的物种组成和群落结构相似。此外，谷物猪粪捕获的总物种丰富度、物种组成和结构与人类粪便相似。因此，虽然谷物猪粪没有采样与人类粪便相似的总丰度，但这种类型的粪便可以有效地准确调查亚马逊雨林中蜣螂的总物种丰富度、物种组成和结构。猪粪类型之间的物种组成和群落结构相似。此外，谷物猪粪捕获的总物种丰富度、物种组成和结构与人类粪便相似。因此，虽然谷物猪粪没有采样与人类粪便相似的总丰度，但这种类型的粪便可以有效地准确调查亚马逊雨林中蜣螂的总物种丰富度、物种组成和结构。
