Necrophagous insects are very important bioindicators in determining the post mortem interval. The objective of this Works was to determine the diversity of Necrophagous insects involved in the décomposition process of a cadaver exposed in the open air in the Sudano-Guinean (Bouaké) and Sub-Sudanese (Korhogo) zones of Côte d'Ivoire.

Twelve pig carcases were used in each agro-ecological zone. Harvesting of adult insects has been done by various traps. Egg samples, larvae and pupae were collected on the corpses then breeded in the laboratory. The necrophagous insects order collected were Beetles and Diptera. In the Diptera, 17 species grouped into six families were collected in each agro-ecological zone. Calliphoridae and Histeridae were the richest in species. Necrophagous insects were collected at various stages of decomposition during all seasons and at both study areas. These could serve as indicators in forensic entomology investigation.
