A corpse constitutes for different species of insects a nourishing substrate, an egg-laying site, a refuge or even an ecological niche. The objective of our study is to know the influence of the conditions of exposure of pig corpses on the composition of the entomological necrophagous fauna in the Guinean zone of Côte d'Ivoire. Twelve pig corpses were exposed under four conditions at the National Agronomic Research Center of Adiopodoumé. The experimental set-up consisted of three series of four types of wire mesh cages each containing a freshly slaughtered pig body: one witness exposed on the ground, one semi-submerged, one wrapped in a shroud and one suspended from a gallows. Two orders of insects were collected: Diptera and Coleoptera represented respectively by seven and eight families. Chrysomya albiceps was most abundant in control and packed cadavers with 14.93 and 11.81% of total Calliphoridae numbers, respectively. Fanniidae, Piophilidae, Muscidae and Stratiomyidae, were not found on the hanging corpses. The family of Coleoptera Histeridae was the most diverse; that of Geotrupidae was not collected from the hanging corpses. The high Shannon index on witness, wrapped and semi-submerged corpses reflects a cohabitation of many species present on these corpses. The high values of Equitability at the level of these same types of cadaver, demonstrated an equitable distribution of species within the corpse ecosystem.
