Necrophagous insects plays an important role, especially in forensic practice, especially in determining the time of death. This work was aimed to monitor necrophagous species of the Diptera order in selected localities of South Moravian Region - Rakvice and Sokolnice. Furthermore, these necrophagous species were identified with anatomical-morphological and molecular genetic methods, which have been compared to each other. For this purpose it was necessary to isolate a DNA segment and amplify cytochrome oxidase I (COI) gene by the PCR method and with further processing to obtain the sequence of selected individuals from the mitochondrial genome. The results of the experiment more coincided with morphological identification database BOLD outputs than with outputs from the BLAST database. Anatomical and morphological identification cannot always accurately determine the genus and species necrophags, the assesment is not dependent not only on the development stage of the insect and its condition, but also on the expertise of the determinator. Most accurater results are achieved with use the combination of anatomical and morphological and molecular-genetic methods of determination, which is confirmed by the results of this thesis.
