Carcaças de vertebrados são exemplos marcantes de recursos efêmeros e pontuais (Hanski 1986), sendo colonizadas por diferentes espécies de animais, dentre as quais se destacam os insetos, principalmente das ordens Diptera e Coleoptera. O estudo da sucessão dessas espécies, bem como o tempo em que vivem na carcaça, pode servir para determinar em quais circunstâncias a morte ocorreu e ainda estimar o intervalo post mortem (IPM) (Keh 1985;Catts & Goff 1992) dentro do escopo da Entomologia Forense.A utilização de insetos em estimativas de IPM tem se baseado principalmente por estes serem as primeiras espécies de animais a encontrar um cadáver, utilizando-o como fonte protéica, sítio de cópula e estímulo a oviposição. Uma outra característica importante é de que, como em qualquer comunidade recém-formada, haverá colonização do ambiente por tantas espécies quanto o recurso permitir, desencadeando um processo de sucessão heterotrófica que, se constante, pode ser altamente informativo (Catts & Goff 1992 ABSTRACT. A study of the Coleoptera (Insecta) fauna that inhabits Sus scrofa L. carcass in Curitiba, Paraná. This paper sought to assess the Coleoptera fauna associated with carcasses of Sus scrofa L., 1758, which is usually used as model in Forensic Entomology. The addition and sequential substitution of insect species could be used to estimate the post mortem interval (PMI). The present study took place in Centro Politécnico (UFPR), between september 2005 to september 2006. A pig weighting 15 kg was sacrificed each season and put inside a cage. Sampling is made daily in a tray placed below the carcass and in a Shannon modified trap, and each 14 days in five pit-fall traps. 4,360 beetles were collected, belonging to 112 species of 26 families, 12 were considered of forensic potential. The active collecting made in the tray was responsible for the largest number of beetles (2,023 specimens), followed by the modified Shannon trap (2,016 specimens) and by the pit-fall traps (324 specimens). Staphylinidae was more abundant in the modified Shannon trap, while Silphidae was more abundant in pit-fall traps. The main habits found are predator/parasite (55%) and omnivorous (38,05%), with only a few species considered necrophagous (1,31%).

“…In cases in which the mummification of the body takes place, even indoors, these beetles can accelerate the skeletonisation process (Voigt, 1965;Schroeder et al, 2002) and, even so, adults and larvae can be found associated with the remains years after death (Byrd and Castner, 2010). In the present study, three individuals of Dermestes haemorrhoidalis Küster, 1852 and 330 individuals of D. maculatus were collected.…”

Beetles (Insecta, Coleoptera) associated with pig carcasses exposed in a Caatinga area, Northeastern Brazil

The species richness, abundance and seasonality of Coleoptera fauna associated with pig carcasses exposed in a Caatinga area were examined. Tray, pitfall and modified Shannon traps were settled together to collect these insects during two seasons (dry and rainy). 4,851 beetles were collected, belonging to 19 families and 88 species. Staphylinidae (2,184) and Histeridae (1,264) were the most abundant families and accounted for 71.1% of the specimens collected. Scarabaeidae (15)

“…La especie Dermestes maculatus ha sido reconocida como un importante componente de la entomofauna cadavérica por estar asociada con la descomposición, tanto en cadáveres humanos como en animales (richardson & Goff, 2001;Schroeder et al, 2002). Las larvas de esta especie han sido colectadas en cadáveres desde los 7 días , 5 meses (Schroeder et al, 2002) hasta 1 a 2 años (oliva, 1997) después del deceso, dependiendo de las condiciones ambientales en que se encuentre el cadáver.…”

IntroduccIónLa aplicación fundamental de la entomología forense es estimar el tiempo trascurrido desde la muerte de una persona hasta el descubrimiento del cadáver, lo que se denomina Intervalo Post Mortem (PMI, siglas en inglés). Generalmente hay dos métodos utilizados en entomología forense para estimar el PMI: el ciclo de vida de las especies colonizadoras primarias y los patrones Rev. Mus. Argentino Cienc. Nat., n.s. 19(2): 225-234, 2017 ISSN 1514-5158 (impresa) ISSN 1853 Asociación y estratificación de la entomofauna cadavérica a diferentes profundidades en el suelo como indicadores complementarios en largos intervalos post mortem Abstract: Association and stratification of cadaveric entomofauna at different depths in the ground as complementary indicators in long post-mortem intervals. In this study the composition of carrion entomofauna in the ground below the carcass one month after the death was e�amined, identifying strata and associas one month after the death was e�amined, identifying strata and associaone month after the death was e�amined, identifying strata and associations to different ground depths. three carcasses were e�amined: two horses and a cow, placed in sandy soil during the spring, summer and autumn in a natural environment in Mendoza. Soil samples were taken from ground surface every 10 cm below the corpse up to a depth of 60 cm. A total of 11,452 specimens (8,576 in autumn, 2,339 in summer, and 537 in spring), belonging to 24 different species belonging to 11 families was collected. Indicator species allowed differentiation of strata in sampled soil under corpses. In spring a first stratum was defined with pupae of Piophila casei (Linnaeus) (Piophilidae) between the surface and 30cm depth and a second stratum was defined at a depth between 40 to 60cm with pupae of a species of Phoridae and eggs of Histeridae. In summer only one stratum was defined by the abundance of puparia of Chrysomya albiceps (Wiedemann) (calliphoridae), located between the surface and 30cm depth. In autumn only one stratum was determined by larvae of Dermestes maculatus de Geer (dermestidae) located between the surface and 20cm depth. the entomological composition varies with depth and between seasons, abundance was higher on the surface. calliphoridae and dermestidae were associated with superficial layers and the genera Euspilotus Lewis (Histeridae) and Omorgus Erichson (trogidae) to deeper layers of the soil.Key words: cadaveric entomofauna, association, stratification, soil, long PMI Resumen: En el presente trabajo se e�aminó la composición de entomofauna cadavérica en el suelo debajo de cadáveres identificando estratos y asociaciones con diferentes profundidades a un mes de producido el deceso. Se utilizaron tres cadáveres (dos caballos y una vaca) dispuestos en suelo arenoso en primavera, verano y otoño en un ambiente natural de Mendoza. Los muestreos se realizaron en el suelo debajo de los cadáveres hasta 60 cm de profundidad. Se colectaron 11452 ejemplares (8576 en otoño, 2339 en verano y 537 en prima...
