“…1). Los especímenes fueron capturados en trampas de botellas cebadas con órganos de pollo (menudos: panza, corazón, hígado, cuello) con un vaso colector que contenía propilenglicol (Aballay et al, 2016), colocadas en la proximidades de hormigueros de Acromyrmex lundii (Guérin-Méneville) y también en ausencia de hormigueros. Se colectaron ejemplares de ambos sexos.…”

“…Tamaño: (rango): PEL = 2,02 -2,57 mm; EW = 1,77 -2,17 mm. Antecedentes biológicos: de los 69 ejemplares revisados en este estudio 68 ejemplares fueron colectados con trampas de botella descriptas en Aballay et al (2016) y cebadas en el interior con órganos de pollo (menudos: panza, corazón, hígado, cuello) con un vaso colector que contenía propilenglicol como conservante. El mayor porcentaje (88,5%) de los ejemplares fueron capturados en trampas de botellas cebadas con órganos de pollo ubicadas en torno a la entrada y en basureros de hormigas cortadoras Acromyrmex lundii (Guérin-Méneville) y el 11,5 % restante fueron capturados en trampas de botellas también cebadas con órganos de pollo, pero en ausencia de hormigueros.…”

12 especies del género Euspilotus fueron colectadas sobre cadáveres de vertebrados en descomposición y fueron incluidas en una clave para su identificación como especies de importancia forense (Aballay et al., 2013). Las especies de este género son en su mayoría depredadoras de larvas y huevos de insectos de cuerpo blando, por este motivo es frecuente colectarlas en hormigueros y cadáveres, donde se desarrollan

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...

“…A number of studies in deserts around the world have stressed the importance of darkling beetles as detritivores in xeric ecosystems, suggesting that they play an important role in the cycle of important soil nutrients (Matthews et al 2010). These insects can behave either as generalist herbivores (Flores & Debandi 2004, Bisigato et al 2015 or as consumers of the senescent vegetation (Ayal 2007, Pizarro-Araya 2010, Cheli 2009 or dead animals (Aballay et al 2016, Cheli 2009). On the other hand, darkling beetles are important prey items for numerous vertebrates, transferring energy from low to higher trophic levels (Ayal & Merkl 1994, Flores, 1998, Formoso et al 2012.…”

Arid lands provide several products and services to humankind, but human activities affect this environment, increasing the extinction risk of the native species.Thus, to successfully conserve the biodiversity of these ecosystems, it is necessary to identify which environmental factors infl uence the spatial distribution of the organisms that offer these benefi ts. Darkling beetles play a relevant role on the functioning of deserts. Although these insects are among the most abundant and diverse in these environments, there is no agreement on the relative importance that different environmental factors have as determinants of their spatial distribution. In this work, we assessed the role of climate, vegetation, and soil variables as factors that determine distribution patterns of darkling beetles within the Natural Protected Area Península Valdés (Northeastern Patagonia). Five groups of environmental units were identifi ed, each one with an exclusive tenebrionid species assemblage and different species diversity. The most infl uential environmental variables were temperature, precipitations, and soil texture. Results suggest that the magnitude of several ecosystem processes may vary among the groups of environmental units. We recommend prioritizing the conservation of the fi ve groups of environmental units and incorporating the darkling beetles-environment relationship in future conservation strategies for arid Patagonia.
