Sarcophagidae (Insecta: Diptera) atraídos por diferentes tecidos suínos em decomposição em área agropastoril de Uberlândia-MG.

Abstract

Several species of flies use decomposing organic matter as food source, in their immature and/or adult forms, and play an important role in the decomposition of animal carcasses. These species can be used as indicators for Forensic Entomology. The present work was carried out in two areas: one forest area and the other pasture area belonging to the Experimental Farm of the Federal University of Uberlândia. Flies from the Sarcophagidae family were captured with traps baited with swine tissues: liver, muscle, brain and intestine, during four days in two periods of 2015, one in the summer in February and the other in August/September in the winter. Throughout the experiment were collected 2.921 individuals of the family Sarcophagidae, belonging to at least 41 species. Flies were more abundant in the dry period. Brain tissue was more attractive than the other tissues for Sarcophagidae. Flies were also more abundant in the forest environment. The genus Oxysarcodexia presented greater abundance with 2.139 individuals and greater diversity with 11 species. The species: Nephochaetopteryx orbitalis, Titanogrypa (Cucullomyia) larvicida, Sarcophaga (Lipoptilocnema) crispula, Oxysarcodexia major, Dexosarcophaga carvalhoi, Peckia (Peckia) chrysostoma and Ravinia advena occurred exclusively in the dry environment. The following species were found exclusively in the forest: Dexosarcophaga carvalhoi, Oxysarcodexia marjor, Nephochaetopteryx pallidiventris, Oxysarcodexia admixta, Oxysarcodexia angrensis, Oxysarcodexia carvalhoi and Oxysarcodexia culminiforceps. The information presented in the present study is of ecological importance and for Forensic Entomology.
