Diversity of coprophagous scarab beetles (Coleoptera, Scarabaeidae) collected with flight intercept trap in the Southern Pantanal, Brazil. Biota Neotrop. 10(2): http://www.biotaneotropica.org.br/v10n2/en/abstract?article+bn03410022010.Abstract: Coprophagous scarab beetles play an important ecological role in the ecosystems; however, studies on diversity of such insects are scarce for distinct biomes. The present study aimed to identify the Scarabaeidae coprophagous species which occur in the Pantanal of Mato Grosso do Sul. This study was carried out at the Nhumirim ranch (Embrapa Pantanal), located in the Nhecolândia sub-region of the Pantanal, from June 1992 to May 1993. For insect sampling, two window flight traps (1 × 1 m) were set up monthly during two to four consecutive days. The traps were placed in an open native grassland area (native pasture) and in a cerradão (dense savanna) area, remaining active from 19:00 PM to 07:00 AM, when caught insects were removed and fixed in 70% alcohol solution. It was collected 19587 individuals of Scarabaeidae, belonging to two subfamilies (Aphodiinae and Scarabaeinae), 11 genera, and 21 species. Resumo: Os besouros coprófagos desempenham grande importância ecológica dentro dos ecossistemas, porém, escassos são os estudos de diversidade desses insetos em diferentes biomas. Assim, desenvolveu-se o presente estudo com o objetivo de identificar as espécies de Scarabaeidae coprófagos que ocorrem no Pantanal de Mato Grosso do Sul. O trabalho foi desenvolvido na fazenda Nhumirim (Embrapa Pantanal), sub-região da Nhecolândia, no período de junho de 1992 a maio de 1993. Para a coleta dos insetos foram instaladas mensalmente duas armadilhas luminosas do tipo "janela" (1 × 1 m), por um período consecutivo de dois a quatro dias. As armadilhas foram alocadas em área de campo (pastagem nativa) e de cerradão (vegetação densa), sendo acionadas às 19:00 horas e desligadas às 07:00 horas do dia seguinte, quando os insetos capturados eram retirados e acondicionados em frascos etiquetados contendo álcool 70%. Foram coletados 19587 exemplares de Scarabaeidae, pertencentes a duas subfamílias (Aphodiinae e Scarabaeinae), 11 gêneros e 21 espécies. As espécies encontradas no Pantanal Sul-Mato-Grossense pertencem aos gêneros Ataenius, Aphodius, Ateuchus, Canthidium, Dichotomius, Labarrus, Nialaphodius, Ontherus, Trichillum, Trichiopsammobius e Uroxys. Dentre os Aphodiinae, Ataenius sp.2 (96,17%) foi a mais abundante. Canthidium sp.1 (0,39%), Dichotomius sp. (0,28%) e D. bos (Blanchard, 1843) (0,16%) foram as mais abundantes dentre os Scarabaeinae. Com relação ao comportamento reprodutivo de nidificação, 42,86% das espécies coletadas apresentaram hábito paracoprídeo (escavadores) e 57,14% endocoprídeo (residentes).

“…Our knowledge of dung beetle communities and their ecological function in Brazilian pastures is still embryonic (Mendes & Linhares, 2006;Silva et al, 2006). An important step towards a more comprehensive evaluation of the potential for native Brazilian dung beetles to act as effective biological control is to improve our understanding of the distribution and functional roles of native beetle communities in introduced pastures across a range of distinct geographical regions.…”

Abstract. 1. Cattle pastures dominated by introduced grasses are a characteristic component of many tropical landscapes in Brazil, yet little information is available concerning the insect communities that inhabit these novel ecosystems.2. Dung beetles are a conspicuous element of pasture insect communities, and make a significant contribution to dung decomposition, parasitic fly control, and soil bioturbation.3. We sampled dung beetle assemblages in twelve introduced pastures near Viçosa, Minas Gerais, Brazil. We used pitfall traps baited separately with cow and horse dung, and collected a total of 456 dung beetles, comprising 23 species from 13 different genera. We analysed patterns of alpha and beta diversity, community structure, and species composition among pastures and bait types.4. Cow dung harboured significantly more species, but a similar abundance of dung beetles compared with horse dung. However, both dung types supported species exclusive to that type, and hosted a distinct dung beetle community structure and composition.5. Although livestock (cattle and horses) was introduced to Brazil less than 500 years ago, our data suggest that novel and well-structured dung beetle communities are actively exploiting these novel food resources in Brazilian pasturelands.

“…Due to edge effects, these places have fewer fruits and more insects. All fragments studied belong to a pasture matrix used for cattle ranching, which would explain the greater number of beetles, once they use feces for feeding and reproduction (MENDES & LINHARES 2006). The greater consumption of beetles in the small fragments can be explained by the extension of the edge, which facilitates the entrance of beetles in areas of the forest.…”
