ABSTRACT
Carrion breeding insects may be of great utility in crimes briefing. Studies on forensic entomology are restricted to few localities in Brazil and very few of them were done in the cerrado vegetation (a type of Savannah) until now. This work aimed to survey the main species of dipterans associated with the decomposition process of Sus scrofa and the insect succession pattern in carcasses in the Cerrado. The study was carried out in the dry and humid season of the year, in two cerrado vegetation profiles in Uberlândia, MG. Two pig carcasses were placed in each vegetation profile and time period of the year. The decomposition process was slower and insects were more abundant in the dry season. Differences in temperature, air humidity and pluvial precipitation seemed to be the main physical factors responsible for the differences in the time of decomposition of the pig carcasses between the two seasons. Fourteen species of dipterans (59,467 specimens) bred in the decomposing carcasses. Chrysomya albiceps (Wiedemann) was the species more abundantly breed in the two periods. The other species that breed in the carcasses were C. putoria (Wiedemann), Hemilucilia segmentaria(Fabricius), Lucilia eximia(Wiedemann) (Calliphoridae), Peckia (Pattonella) intermutans(Walker), Peckia (Squamatoides) trivitatta(Curran), Sarcodexia lambens(Wiedemann) (Sarcophagidae), Musca domestica(L.), Ophyra aenescens(Wiedemann), Stomoxys calcitransL. (Muscidae), Fannia pusio(Wiedemann), Fannia sp. (Fanniidae), Hermetia illuscens L. (Stratiomyidae) and Phoridae sp. The Cerrado of this region presents many dipterans potential forensic indicators.
RESUMO
Os insetos podem ser de grande utilidade no auxílio de elucidações de crimes. Estudos de entomologia forense ainda estão restritos a poucas localidades no Brasil e são escassos na vegetação de cerrado. Este estudo teve por objetivo identificar as principais espécies de Diptera associadas ao processo de decomposição de carcaças de suínos Sus scrofa e o padrão de sucessão de insetos nesse tipo de substrato. Foram realizados dois experimentos nos períodos seco e úmido do ano em duas áreas de cerrado no município de Uberlândia, MG. Foram utilizadas duas carcaças de suínos em cada ambiente e período do ano. O processo de decomposição foi mais lento no período seco, assim como a maior quantidade de insetos coletados. Diferenças na temperatura, umidade e precipitação pluviométrica parecem ter sido os principais responsáveis pelas diferenças nos tempos de decomposição entre os dois períodos do ano. Quatorze espécies (59.467 espécimes) foram coletadas nas carcaças em decomposição. Chrysomya albiceps (Wiedemann) was the species more abundantly breed in the two periods. The other species that breed in the carcasses were C. putoria (Wiedemann), Hemilucilia segmentaria(Fabricius), Lucilia eximia(Wiedemann) (Calliphoridae), Peckia (Pattonella) intermutans(Walker), Peckia (Squamatoides) trivitatta(Curran), Sarcodexia lambens(Wiedemann) (Sarcophagidae), Musca domestica(L.), Ophyra aenescens(Wiedemann), Stomoxys calcitransL. (Muscidae), Fannia pusio(Wiedemann), Fannia sp. (Fanniidae), Hermetia illuscens L. (Stratiomyidae) e Phoridae sp. O cerrado dessa região apresenta vários dípteros potenciais indicadores forenses.
