The current study was carried out at the Department of Zoology and Entomology, Faculty of Science, Al-Azhar University, Nasr City, Cairo, Egypt by using the dog, Canis lupus familiaris and the rabbit, Lepus cuniculus carcasses as human models. Eight dog carcasses and eight rabbit carcasses were employed in four seasons. The relative abundance of insect species that collected in dog carcasses placed outdoor during the study period was arranged as follows: Chrysomya albiceps, followed by Musca domestica, Dermestes maculatus, Piophila casei, Hister sp., Monomorium pharoensis, Musca sorbens, Necrobia rufipes, Sarcophaga carnaria, Nasonia vetripennis, Calliphora sp., Wohlfartia magnifica, Megaselia scalaris, Chrysomya megacephala, Lucilia sp., Vespa orientalis, Creophilous maxillosous, Stomoxys calcitrans, Dolichovespula sp., Cataglyphis bicolor, and Phormia regina, while the number of occurrence of insect species collected in dog carcasses placed indoor, were arranged as follows: Nasonia vetripennis, followed by Chrysomya albiceps, Dermestes maculatus, Musca sorbens, Megaselia scalaris, Necrobia rufipes, Monomorium pharoensis, Hister sp., Musca domestica, Sarcophaga carnaria, Calliphora sp., Creophilous maxillosous, and Wohlfartia magnifica. On the other hand, the abundance of insect species collected in rabbit carcasses placed outdoor during the study period was arranged as follows: Chrysomya albiceps, followed by Musca domestica, Piophila casei, Hister sp., Dermestes maculatus, Monomorium pharoensis, Nasonia vetripennis, Musca sorbens, Sarcophaga carinaria, Megaselia scalaris, Wohlfartia magnifica, Lucilia sericata., Calliphora sp., Vespa orientalis, Creophilous maxillosous, Cataglyphis bicolor, Chrysomya megacephala, Necrobia rufipes, and Dolicho vespula sp., whilethe frequency of insect species collected from rabbit carcasses placed indoor, were arranged as follows: Nasonia vetripennis, followed by Chrysomya albiceps, Dermestes maculatus, Megaselia scalaris, Musca sorbens, Musca domestica, Monomorium pharoensis, Hister sp., Sarcophaga carnaria, Calliphora sp., and Cataglyphis bicolor. In order to estimate the postmortem interval (PMI), the life table of Chrysomya albiceps as the first and predominant fly arrive the carcass was studied on dog and rabbit carcasses placed outdoors and indoors.
