Abnormal Succession of Insect Fauna on Pig Carcasses in Tandil (Argentina, Buenos Aires Province)

Abstract

This project was an attempt to reconstruct a death in dubious circumstance which happened in December 2002 in Tandil (Buenos Aires Province). Although the body was in open air, the entomological expertise discovered signs of delayed colonization. In this experiment, pig carcasses used as models to reconstruct the case. One was placed in shadow and another in sunlight (control). The hypothesis was that the climate and the topography affect the necrophagous insect succession in a mountain site. The families of Coleoptera found on the baits were: Silphidae, Dermestidae, Cleridae, Histeridae; of Díptera: Calliphoridae, Sarcophagidae; Asilidae; of Hymenoptera: Formicidae, Encyrtidae and Vespidae.

Associational Patterns of Scavenger Beetles to Decomposition Stages

“…Because there is usually uniformity in the trophic roles and habits of species belonging to a particular family of the cadaveric community and studies in the temperate region and other regions of Argentina are still scarce , we aimed to describe and analyze the composition, abundance, and diversity of cadaveric beetles at the family level, including also an analysis at the species level. We also intended to establish possible colonization patterns of beetles and their association with decomposition stages in vertebrate corpses, as well as with the rest of the cadaveric fauna, in a semirural area in the temperate region of Argentina.…”
