Abstract: After death of animal, necrophagous insect invade the death boby for many reasons. These carcasses provide a nourishing substrate, eggs laying area, a breeding site, a refuge for this specific group of arthropod that can be used as valuable auxiliaries of justice. These organisms can help to determine the time elapse since death, the movement of the corpse after crime for Human beings, the abandon of elderly and the cause of death. The exploitation of these insect for criminal purpose is delicate since they are subject of attack by parasitoïds that can affect their life cycle witch is the main key of the use of insect on forensic research. The aim of this research work is to collected necrophagous insects and assess their level of parasitoïdism during their larval rearing in the laboratory under natural ambient air conditions during the dry season. The experiment was performed on two rat carcasses Rattus norvegicus at the field of the University of Yaounde 1. These cadavers were placed inside a wooden cage where the insects were captured during the decay process. After the larvae migration, they were carried to the laboratory alongside the beneath soil for rearing procedure until the emergence of the adulthood that were then identified and their level of parasitoïdism estimate. During the whole experiment, 1976 individuals were sample with 121 captured in the field and 1855 emerged from the rearing in the laboratory. These flies belongs to 2 orders (Diptera and Coleoptera), 6 families [(Calliphoridae, Muscidae, Sarcophagidae, Tachinidae (parasitoïds), Dermestidae and Histeridae (Coleoptera)].
