Dípteros muscoides (Díptera: Muscomorpha) associados a carcaças de porcos domésticos Sus scrofa L. coletados no Parque Estadual da Pedra Branca, RJ, Brasil

Abstract

CHAPTER I - In the field of forensic entomology, the taxonomic identification is essential to proceed to any procedure. Insects are important in the decomposition of cadavers. The use of these insects in medico criminal investigation is the object of forensic entomological studies; the flies are generally attracted to cadavers and one of the most important contributions is to estimate the postmortem interval. The scanning electron microscopy, which allows rapid and accurate identification of different species of forensics flies, has been highlighted as it allows better visualization of the external morphology of immature and some adults. The aim of this study is to describe some ultrastructures of five flies in the Muscidae Family, Morellia humeralis, Biopyrellia bipuncta, Ophyra aenescens, O. albuquerquei and O. chalcogaster, all examined by scanning electron microscopy to help increase the anatomical database on flies of forensic importance.
