“…In the present study, Calliphoridae was observed to be the most diverse dipterous family represented by 6 species; this is contrary to Silva et al [46] and Mabika et al [47] where Muscidae was the most diverse family in their study. Among Calliphoridae, Chrysomya albiceps was numerically dominant one as observed in the studies of Abd El-bar & Sawaby [16] , Polat & Kökdener [38] , and Keshavarzi et al [48] , since this species was considered a very good competitor with others in regard with its feeding on the corpse as well as its predatory behavior on the other larvae infesting the carrions as mentioned by Tantawi et al [21] , Ibrahim et al [23] and Silva et al [46].…”

This study gives out the identification of insect faunal waves colonizing decomposing carrions of rabbits and guinea pigs treated with certain drug agent (tramadol) in Cairo, Egypt. Each of six rabbits and six guinea pigs is divided into 2 groups, where the first was killed by tramadol and the second group was killed by asphyxia as a control experiment. Generally, decomposition process was observed to have a slower rate in winter. Reaching to the skeletal stage was delayed in tramadolintoxicated carcasses in comparing to the control carcasses. A total of 12966 arthropod individuals (Immature stages and adults) were collected. In concern of class Insecta, 67 species belonging to 6 Insecta orders and 2 Arachnida orders, 37 families and 51 genera were identified from this study during winter and summer seasons. Significantly lower numbers of immatures were observed and collected in the present study from the treated carcasses. The proportions of adult insects were also significantly different in control carcasses when compared with tramadol intoxicated ones in both winter and summer season for both rabbits and guinea pigs. This study provides background for the influence of tramadol on the colonizing wave of arthropod fauna which is of relevance to forensic science. We can conclude that drugs and toxins present in a decomposing body may alter the rate of insect invasion of that body.

“…The abundance of M. domestica (with a total of 707 individuals) was higher compared to any other species of the Order Diptera, similar to what has been reported in previous studies (Battan-Horenstein & Gleiser, 2018). Other studies described other species of Muscidae, such as Ophyra albuquerquei Lopes, 1985 as the predominant in vertebrate carcasses (da Silva et al, 2014). In the present study, M. domestica was found mostly in larval form in the fresh-swollen decomposing state.…”

La presente investigación evalúa la entomofauna cadavérica en vertebrados marinos varados en la costa central del Perú. Se determinó la diversidad de la entomofauna presente en diferentes estados de descomposición de 291 carcasas de 18 especies de vertebrados marinos. Cada vertebrado fue asignado a uno de los cinco estados de descomposición del cadáver: (1) fresco, (2) hinchado, (3) descomposición activa, (4) descomposición avanzada y (5) restos esqueléticos. Con relación al número total de cadáveres y de riqueza de especies, las aves fueron las dominantes. Las cuatro especies de vertebrados con mayor número de cadáveres correspondieron a Otaria flavescens (Shaw, 1800), Sula variegata (Tschudi, 1843), Pelecanus thagus (Molina, 1782) y Phalacrocorax brasilianus (Gmelin, 1789). La descomposición avanzada y los restos esqueléticos fueron los cadáveres más frecuentes. Los cuatro Órdenes de la entomofauna cadavérica presentes fueron Dermaptera, Hymenoptera, Coleoptera y Diptera, siendo Tenebrionidae y Muscidae las dos familias más abundantes. Para los coleópteros las cuatro especies principales fueron Phaleria gayi, Dermestes maculatus, Phaleria maculata y Dermestes frischii, y para los dípterosfueron Musca domestica, Lucilia sericata, Sarcophaga sp., Piophila casei y Calliphora nigribasis. Con relación a los servicios ecosistémicos, se observó la siguiente secuencia con base en la riqueza y abundancia de especies: necrófagos > necrófilos > omnívoros. Los índices de diversidad alfa y beta mostraron diferentes patrones según el estado de desarrollo de la entomofauna, el estado de descomposición de los cadáveres, los años de evaluación y según los cuatro cadáveres de vertebrados más frecuentes.

“…Family Calliphoridae was represented by two species (C. albiceps and L. cuprina) in this study. However, C. albiceps was the numerically predominant calliphorid species in our study as noticed in the other studies of Abd El-bar and Sawaby ( 2011) and Keshavarzi et al (2015), since this species was considered a very good competitive with other species in concern with its feeding on the carcass as well as its predatory behavior on the other maggots infesting the cadavers as stated by Silva et al (2014).This explains the occurrence of dead maggots of S. ruficornis and W. magnifica near the cadavers throughout the experiments and also explains its dominance over the other calliphorid maggots as stated by Al-Mesbah et al (2012).…”

This work aims to compare between the forensic insect species, their succession patterns and decomposition stages of rabbit corpses killed with different methods in Qena city, Egypt. Four experiments were carried out during this study for four successive seasons. Four rabbits were placed in each experiment, the first two rabbits received a double LD50 of tramadol hydrochloride and cypermethrin via ear vein injection. The third rabbit was slaughtered while the fourth rabbit was euthanized with air injection (control). The LD50 of tramadol and cypermethrin in male rabbit was calculated from logarithmic scale and found to be 132 mg/kg and 126 µ|/kg body weight, respectively.Currently, a total of 14271 insect individuals were collected from the screened bodies belonging to three orders, thirteen families and seventeen species. Moreover, corpses were colonized by different insect life stages (11689, 352 and 2230 individuals) included dipteran flies, Coleopteran and Hymenopteran insects, respectively The total number of species collected in summer was lower than in other seasons. Tramadol-treated rabbits decayed with similar rate to the control corpses during all seasons except in winter. As well as, decomposition process was significantly prolonged in cypermethrin killed rabbits during all seasons. However, slaughtered carrions decayed faster than control in winter and spring. Maggots deposited on cypermethrin-intoxicated carrions were very few and have been dead after few days from oviposition. Density of maggots collected from control corpse was loweras compared to the slaughtered one and higher than that on tramadol treated corpse. Therefore, these results are recommended to be taken in criminal investigations.
