Entomologia forense : Importância da identificação das moscas necrófagas no município de Bacabal-MA

Abstract

Forensic entomology is an area of forensic science that encompasses the study of mites, some arthropods and, in particular, insects found on corpses. This highlights its importance for criminal expertise, thus establishing the relationship between biology and the legal system, since it helps, through forensic procedures, to verify, prove or demonstrate the veracity of a situation or analysis, as occurs in cases of violent deaths. In this sense, there is a greater emphasis on flies from the families Sarcophagidae, Muscidae and, above all, Calliphoridae, all of which belong to the order Diptera and of great forensic importance. In view of this, this study had the general objective of dealing with the importance of identifying the scavenger flies found in the municipality of Bacabal - MA, as well as their development stages. Therefore, for this to be possible, was used as a methodology to carry out a field research in three different places, in which samples were collected using traps, and a laboratory survey for the metamorphic verification of the collected samples, which subsequently had their data quantitatively planned. With the research, it was possible to verify that the flies, in fact, have a fast life cycle, since four days after placing the trap in Povoado Limeira there was already the presence of pupae in the soil. Along with this, configuring itself as another evidence of such speed, eight days after the larvae were placed for rearing, one of them completed the development cycle. In summary, all the defined objectives were achieved, from installing traps and capturing flies to metamorphic observation and sample identification, thus resulting in a total of 7 species of the Calliphoridae family: Chrysomya albiceps (Wiedemann, 1819), Chrysomya megacephala (Fabricius, 1794), Cochilomyla macellaria (Fabricius, 1775), Hemilucilia souzalopesi (Mello, 1972), Hemilucilia benoisti (Séguy, 1925), Hemilucilia segmentaria (Fabricius, 1805) e Lucilia eximia (Wiedemann, 1819).
