Abstract The study sites were located on the south valley university land in Qena city, Egypt. Study was conducted for one year at two different habitats. For each season, two sites were selected, one outdoor habitat and the other indoor habitat. Sites for carcass placement were chosen on the roof of faculty of science (outdoor environment) and at room on the basement of the faculty (indoor environment).The rabbits, Oryctolagus cuniculus, are chosen to simulate the soft skin of a new baby and they were characterized by a relatively uniform size. The mentioned rabbits were purchased locally with different colors but comparable in size. On the delivery day of each season, rabbits were weighed, and then euthanized with air injection to mimic the normal death case without any chemicals or drugs. After death, the animals were immediately delivered post-mortem to the research sites in an appropriate man-made plastic traps which were designed specifically to allow insect access, but prevent them escaping. For this purpose, each trap was composed from two parts, the lower part was designed for placement of dead rabbits, while the upper part act as collection chamber of insects. Five holes were made on the sides of lower part to allow access for the insects to oviposit on the carrions, but without attempts to escape because they were made their way to the upper part of trap to be collected. Then, animals were immediately placed into plastic traps and left exposed to natural conditions. Each rabbit was placed on its side. All rabbits were placed within one hour of the time of death. A tray containing sawdust was placed under each cage to facilitate the collection of larvae leaving carrions for pupation Three experiments were conducted in each season. Four rabbit carcasses were placed in each experiment, two at the indoor habitat and two at the outdoor habitat. All efforts were made to keep cadaver disturbance to a minimum during taking samples. All rabbits were placed on their side. Observations, photographs, temperature, humidity readings and sample collections were made daily at varying times of the day according to each experiment. The temperatures and humidity readings were taken with digital thermometer. |
