Coleoptera associated with pig carcass exposed in a forest reserve, Manaus, Amazonas, Brazil

Abstract

L.M. Coleoptera associated with pig carcass exposed in a forest reserve, Manaus, Amazonas, Brazil. Biota Neotrop. 10(1): http://www. biotaneotropica.org.br/v10n1/en/abstract?inventory+bn03110012010. Abstract:The Coleoptera fauna of forensic importance associated with Sus scrofa Linnaeus, 1758 carcass decomposition in Ducke Reserve, Manaus, Brazil, was determined. A total of 41 species, belonging to six families and 11 subfamilies were collected. Staphylinidae presented the higher richness with 17 species sampled, followed by Histeridae, with 11 and Scarabaeidae with nine species. Euspilotus azureus (Sahlberg, 1823) (Histeridae), Aleochara sp. (Staphylinidae) and Oxelytrum cayennense (Stürm, 1826) (Silphidae) occurred in all stages of decomposition. Omalodes lucidus Erichson, 1824 and Scapomegas auritus Marseul, 1855 (Histeridae) are recorded for the first time in the Amazon, being also reported for the first time associated with a decomposing carcass. The fauna differs from those of other Brazilian regions, emphasizing the importance of studies to determine the regional insect fauna of forensic importance that can be used in criminal investigations.

Temporal distribution of blowflies of forensic importance (Diptera: Calliphoridae), in man-size domestic pigs carcasses, in the Forest Reserve Adolpho Ducke, Manaus, Amazonas, Brazil

“…The published Brazilian studies on forensic ecological communities, that used domestic pigs as models, also used pseudoreplicates (CarvalhO et al 2000;CarvalhO et al 2001CarvalhO et al , 2004marChiOri et al 2000;Oliveira-da-silva et al (2006);BarBOsa et al 2010;Biavati et al 2010;Mise et al 2010).…”

“…Half of the published studies aimed at bionomic aspects (Fraga 2004;Oliveira-da-silva et al 2006;BarrOs-de-sOusa et al 20012. The other half covered taphonomic and ecological aspects mise et al 2010;ururahy-rOdrigues et al 2010). Studies of community ecology are fundamental to the formation of databases and to point out the best forensic indicators for the Amazon region, as well as for other Brazilian regions.…”

Papel dos besouros (Insecta, Coleoptera) na Entomologia Forense

“…Duas espécies são conhecidas colonizadoras de carcaças no Brasil: Oxelytrum discicolle (Brullé, 1840), encontrada em São Paulo e no Sul do país [50 -52]; e Oxelytrum cayennense (Sturm, 1826), espécie endêmica da Floresta Amazônica [35,53].…”

“…Nos últimos anos, além de estudos desenvolvidos no Paraná [50,56,57], importantes contribuições para o conhecimento da coleopterofauna associada a carcaças no Brasil foram dadas com pesquisas em áreas de Floresta Amazônica [12,35,53], Cerrado [38] e Caatinga [21,47,58]. Grande riqueza de coleópteros habitando as carcaças está presente, por exemplo, nos trabalhos de Luederwaldt [44], Mise et al [50] e Santos et al [58] que coletaram respectivamente 62, 112 e 88 espécies.…”

“…Por exemplo, aparentemente, besouros das famílias Dermestidae e Cleridae preferem ambientes mais áridos [21,38,47,58], embora haja registros em menor abundância para outros ambientes [37,50], enquanto os da família Silphidae são exclusivos de ambientes mais úmidos, não sendo registrados no Nordeste do país [35,53]. Essas diferenças assinalam a importância da coleta de dados locais para a prática da entomologia forense no Brasil.…”
