Entomofauna associada a cadáver de porco doméstico (Sus scrofa (L.)) em área urbana de Trindade, GO

Abstract

ABSTRACT: Insects may play different roles of interest to humans. It is event of forensic entomology, science that uses the knowledge about the insects and other arthropods as a tool to solve cases of crimes in various situations. This paper examined the diversity of the fauna insects in the process of ecological succession associated with different stages of decomposition of a corpse of domestic pig (Sus scrofa (L.)). The experiment was conducted in the Faculty União de Goyazes in the municipality of Trindade-Go. The study was done by means of the capture of insects using a Shannon trap modified and pitfall traps (pit fall). We collected 4590 species divided into seven orders. The most abundant orders were Diptera (65.82 %), Hymenoptera (18.91 %), Coleoptera (14.49 %). The families of Diptera more abundant were Calliphoridae (59.28 %), Muscidae (36.75 %) and Sarcophagidae (3.45 %). The family of Hymenoptera most abundant was Formicidae (99 %). The families of Coleoptera of forensic interest collected more abundant were Dermestidae (72.18 %), Cleridae (19.24 %), Histeridae (2.85 %), Scarabaeidae (2.41 % ), Carabidae (1.82 %) and Silphidae (1.05 % ). Dipteras had a preference for fresh phases and swelling while Coleopteras had predilection for stages of deterioration and drought. All the families identified have been found in recent studies, and demonstrate the importance of studies to understand the pattern of succession of insects in corpses, thus contributing to studies in medical criminal investigations.
