“…Se han capturado ejemplares de la familia Cleridae desde los primeros estados de descomposición, estados en que fueron citados por diversos autores (Rodriguez & Bass, 1983;Byrd & Castner, 2000) . En este estudio no se encontraron larvas de esta familia, mientras que Anderson et al, (1996), las recolectaron a partir del día noventa y cuatro de exposición.…”

IntroducciónSe han estudiado las especies de coleópteros necrófagos asociadas a cadáveres de cerdos. El experimento se ha realizado durante las cuatro estaciones del año y en dos ambientes distintos, exponiendo los cadáveres al sol y a la sombra. Algunas especies de coleópteros aparecen frecuentemente asociadas a los cadáveres pues se alimentan de carroña o de los artrópodos que se encuentran en ese medio cadavérico. Los estadios larvarios de estos coleópteros, son necrófagos (Braack, 1987;Catts & Goff, 1992). También se ha estudiado la participación de estos coleópteros en el proceso de descomposición, constatando si hubo o no, distribución exclusiva de especies por zonas y estaciones, y comprobando si su acción depredadora alteró el proceso de descomposición.Los resultados de este estudio servirán para documentar datos de las especies que puedan ser útiles a la entomología forense, disciplina que combina la entomología con las ciencias médicas legales y forenses, con el fin de esclarecer algunas de las incógnitas que generalmente rodean a los cadá-* c/ Albalate nº 13. 22510 Binaced (Huesca). M. Castillo-Miralbés (*) RESUMENLa finalidad del estudio es averiguar cuáles son los coleópteros necrófagos más frecuentes en un hábitat carroñero, utilizando cadáveres de cerdos, en la comarca de La Litera en Huesca, durante las cuatro estaciones del año y en dos ambientes distintos, al sol y a la sombra. En total se identificaron dieciocho especies pertenecientes a cinco familias de coleópteros. Palabras clave: Coleoptera, Cleridae, Cholevidae, Dermestidae, Nitidulidae, Silphidae, necrófagos, carroña, Huesca, España. ABSTRACTMain species of "Necrophagous Coleoptera" collected on pig carrion in "La Litera region" (Huesca)The purpose of the investigation carried out was to find out which are the "Necrophagous Coleoptera" arriving to carrion most frequently. Domestic pig carcasses were exposed in two different sites (sun and shade) during the four seasons of the year in "La Litera region", Huesca. Eighteen "Coleoptera species" were identified taxonomically belonging to five different families.

“…1-4). Rodriguez & Bass (1983), em cadáveres humanos, encontraram Histeridae na fase inchada e no começo da fase de putrefação, coincidindo com o pico populacional destes insetos no presente estudo. Cleridae, Dermestidae e Scarabaeidae foram encontradas na maior parte na fase seca, também coincidindo com o encontrado por aquele autor.…”

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%).

“…On each site, a "IHM -0172SI" thermohygrometer recorder was installed to record daily atmospheric temperatures and relative humidity. Rainfall data were provided by the Meteorological Service of SODEXAM -Abidjan (Société d'Exploitation et de Developpement Aeroportuaire, Aeronautique et Meteorologique).The choice of domestic pigs as biological material is explained by the fact that it is considered an excellent model for the decomposition of the human corpse (Anderson and Van Laerhoven, 1996, Rodriguez and Bass, 1983, Catts and Goff, 1992. There were six (06) pig corpses in the study, two (02) per site and one (01) per grid.…”

Article InfoThe aim of this work was to demonstrate the existence of a diverse necrophagous entomological fauna and the order in which these insects appear to colonize a decaying corpse in the open air in the southern forest zone of Côte d'Ivoire. At the three sites selected in the city of Abidjan, Calliphoridae Diptera (1058±129.73 individuals trapped), Sarcophagidae (317.33±14.38) and Muscidae (152.33±11.46), occurring between the 1st and 14th post mortem days, were the first group of insects that colonized the exposed pig carcasses. Between the 14th and the 28th day post mortem, a second group mainly composed of Piophilidae Diptera (767±87.30 individuals harvested) and Coleoptera belonging to the Cleridae (803.33±73.64) and Histeridae families(15.67±1.85), appeared. The family of Stratiomyidae (339.67±49.76 individuals trapped) occurred between the 35th and 42nd post mortem days. These formed with the Piophilidae and the Cleridae, the third group that stayed until the 91st day post mortem. During the advanced decomposition phase, the Coleoptera Dermestidae, Tenebrionidae and Trogiidae appeared. They were added to the necrophagous insects of the third group to constitute the fourth group.The identification of the necrophagous Diptera trapped, made it possible to note the preponderance of the genera Piophila spp. and Chrysomya spp. They represented for 29.12% and 26.57% respectively of the total number of Diptera trapped. The least represented genera were Musca spp. and Calliphora spp. with 5.78% and 3.45% of the total number of Diptera harvested. For Coleoptera, the Cleridae family was the most represented with 91.01% of the total number of individuals harvested at the three sites.As part of an entomological assessment to date a death, these first results give an overview of the entomological fauna existing in the Guinean zone of Côte d'Ivoire and the way it gradually colonizes, a corpse exposed to the outdoors.
