          Abstract

          In this study, performed in a remnant of Brazilian Atlantic Forest, three types of dung from animals with distinct alimentary habits were utilized, in order to verify possible differences of attractivity of these dungs to the Scarabaeinae and the influence of seasonality in the attractivity. Three habitats were sampled: edge, clearing and forest core, each with 40 pitfall traps. A total of 2,137 beetles were collected from August 2005 to July 2006. Canthidium sp. 1 (43%) and Dichotomius sericeus (41%) were the most abundant species. From the total number of beetles collected, 80.5% were attracted to human dung, 11% to jaguar dung, 7.8% to waterbuck dung and 0.7% to the control. The species Canthidium sp.1, Canthidium sp. 2, Ateuchus sp., Canthon nigripenne, Canthonella sp. and D. sericeus came to all three bait types. Eight species were found in the baits with human dung, where Canthidium sp.1 (49%) and D. sericeus (39%) were the most common. A significant difference in attractiveness of the different baits was observed; the highest abundance found in traps baited with human dung (F = 36.59; g.l. = 3; p < 0.0001). A significant difference in richness was observed between rainy and dry seasons (F = 12.29; g.l. = 1; p < 0.001), the highest richness found in the dry season.

          Nesse estudo, realizado em um remanescente de Floresta Atlântica Brasileira, três tipos de fezes de animais com distintos hábitos alimentares foram utilizados para verificar possíveis diferenças de atratividade dessas fezes por Scarabaeinae e a influência da sazonalidade nessa atratividade. Três habitats foram amostrados: borda, clareira e núcleo da floresta, cada um com 40 armadilhas de queda ("pitfall"). Um total de 2137 besouros foi coletado de agosto de 2005 a julho de 2006. Canthidium sp. 1 (43%) e Dichotomius sericeus (41%) foram as espécies mais abundantes. Do número total de besouros coletados, 80,5% foram atraídos para fezes humanas, 11% para fezes de jaguar, 7,8% para fezes de cobo e 0,7% para o controle. As espécies Canthidium sp.1, Canthidium sp. 2, Ateuchus sp., Canthon nigripenne, Canthonella sp. e D. sericeus foram aos três tipos de isca. Oito espécies foram encontradas nas iscas com fezes humanas, onde Canthidium sp.1 (49%) e D. sericeus (39%) foram as mais abundantes. Diferença significativa de atratividade por diferentes iscas foi observada; a maior abundância foi evidenciada em armadilhas iscadas com fezes humanas (F = 36.59; g.l. = 3; p < 0.0001). Diferença significativa foi observada na riqueza entre as estações chuvosa e seca (F = 12.29; g.l. = 1; p < 0.001) sendo a maior riqueza verificada na estação seca.
