Diversidade e aspectos da biologia de Fanniidae e Muscidae (Diptera: Muscomorpha) atraídos e criados em vários tecidos/substratos de origem suína em Uberlândia, MG

Abstract

The superfamily Muscoidea is composed by families, Anthomyiidae Fanniidae and Muscidae. The individuals of this taxon may be scanvengers or predators and their larvae can be found in many habitats of which stands out the animal organic matter. In this presente study, were collected flies in the urban area of Uberlândia-MG with the main purpose to acquire knowledge about the richness and biological aspects of the necrophagous species of the family Muscidae and Fanniidae for forensic interest. Four traps were used with diferente tissues and parts of the swine (brain, liver, intestine, muscle and lung) to atract the flies. The traps mentioned were exposed in an open area of the Umuarama Campus of the Federal University of Uberlândia. The total of individuals that were collected belonging to four species of Muscidae and at least one of Fanniidae were 480 (fourhundred and eighty). The substrates were taken to the laboratory for monitoring of the larval development until the emergence of the adult flies. Emerged 18 (eighteen) individuals belonging to the genus Fannia sp (Fanniidae). The swine tissue that was most atractive substrate to the flies was the liver (n= 281) while the brain showed the highest rate of creation (n= 17). Musca domestica was the most abundant species among the drawn flies and Fannia sp1was the only one that developed in substrates. The data and information obtained about the fauna drawn and the ones that developed are important so that the cientific comunity can know the species of the region that are decomposing the organic matter. The information about the degree of the attractiveness of the flies species to diferent tissue/organs increases knowledge about potential necrophagous species for forensic interest. The data concerning the de development time of the species is very important to forensic entomology because it helps to estimate the postmortem time.
