“…The presence of L. eximia during this phase corroborates the data obtained by Souza and researchers [48] as well as its presence in all seasons. The results of the fly species found in this study, approach the species identified in the study by Oliveira-Costa et al [7] in an experiment in the city of Rio de Janeiro, Brazil. More recently, Salem et al [52] report on their studies in Egypt, the results of Chrysomyinae specimens belonging to three forensically important.…”

“…In recent decades, there has although there are insect knowledge of the use records for forensic application, historically, the early works were influenced by studies by Jean Pierre Megnin in the second half of the nineteenth century [4]. Currently several publications on the subject has been discussed by several authors [5][6][7][8]. But in the center west of Brazil, the state of Mato Grosso; this issue is rarely addressed.…”

Forensic entomology is the science that uses insects found on bodies to set the Post Mortem Interval (PMI) among other investigations. The present work used DNA barcode based on the use of a standardized fragment of Cytochrome C Oxidase subunit I (COI). We undertook analysis of the taxa associated with carcasses, representing 15 dipterans species. Carcasses of pigs during the decomposition process were used, using a cutoff value of 3% for intra-and interspecific differentiation proves efficient for the dipteran of forensic interest. Species identification is more accurate in well studied and reviewed groups. It was observed that specific taxonomic groups were well separated. In the larger group a molecular study, including other mitochondrial genes and nuclear genes is necessary. The greater differentiation in Lucilia eximia probably requires review studies of the group.

“…In this study, calliphorid flies appeared on the carcasses at the fresh, bloated, and active decay stages of decomposition, whereas some individuals were previously observed during advanced and skeletonization stages (El-Ghaffar et al, 2008;Oliveira-Costa, Lamego, Couri, & Mello-Patiu, 2013& Zeariya et al, 2015, while Abouzied (2014) observed calliphorid flies during the fresh and bloated stages only. A total of 1017 individuals of Sarcophagids representing 3 species (Wohlfarhtia nuba, Sarcophaga hertipes, and Sarcophaga argyrostoma) were collected from this study.…”

Background: Forensic entomology is an increasing area of research, focuses on the violent crime, and deals with the necrophagous-feeding insects that typically decompose carcasses. The present study aimed to update the baseline data of the decay process and its associated successive waves of necrophagous flies on rabbits placed in an urban city (Cairo, Egypt) in spring season. Results: Six rabbits divided equally into two groups were used. The first group was killed by asphyxia via hanging and marked as the control (C), while the second group was intoxicated with rodenticide warfarin (WI). The fresh, bloated, active decay, advanced decay, and skeletal stages of decomposition were observed and defined in all carcasses. Out of 30 insect families collected, 3 families were more common (Calliphoridae, Muscidae, and Sarcophagidae). Thirteen insect families were collected of which Calliphoridae, Muscidae, and Sarcophagidae were common. A total of 10,121 individuals (immature and adult stages) of 26 species were collected, of which Chrysomya rufifacies was the most common species on both types of carcasses (14.7%) followed by Musca domestica, Chrysomya megacephala, Chrysomya albiceps, Muscina stabulans, Sarcophaga hertipes, Calliphora vicina, Musca sorbens, Lucilia cuprina, Sarcophaga argyrostoma, and Lucilia sericata (2.0-12.4%). The other 15 species were represented by small numbers (cumulatively 2.9%). Among the collected flies, Scathophaga litorea (Scathophagidae) was reported for the first time as a new report in Egypt. Unexpectedly, significantly more adults and immatures were attracted to WI than to C carcasses (P < 0.05). Conclusion: This study investigated the rabbit carrion dipteran necrophagous fauna as a model which may be of value for medico-legal cases.

“…Also, they are the first insects to reach the carcass, appearing in the first few hours after the death. Due to that and other aspects, they have been used as important forensic indicators (Battán Horenstein et al, 2010;Oliveira-Costa et al, 2014).…”

First list of parasitoids in flies of medical, veterinary, and forensic importance in Rio Grande do Sul – Brazil

et al. 2022

Necrophagous flies are of great importance for human and animal health. In places where their development occurs, parasitoids can be used as a tool to control these dipterans. In Brazil, the fauna of these parasitoids has been investigated in some regions. However, in Rio Grande do Sul, it is known the occurrence of only one species. Thus, this study aimed to create the first list of parasitoids in flies of medical and veterinary importance in Southern Brazil. Collections took place in the municipality of Pelotas (31º 42’ S; 52º 18’ W). Three replicates consisting of a 500 g bovine liver chunk placed in a tray were exposed to open air for 20 days. Then pupae were individualized and observed until their emergence. We identified 4,882 adult flies of Calliphoridae, Fanniidae, Muscidae, and Sarcophagidae. 4,040 parasitoids emerged, belonging to eight species, of which Nasonia vitripennis, Spalangia cameroni, Spalangia chontalensis, and Tachinephagus zealandicus are new records in Rio Grande do Sul state. Also, three undescribed species of the genus Aphaereta were collected. In spite of being the first attempt to inventory the fauna of hymenopteran parasitoids, this study may help in the development of management programs of these dipterans in the region.
