Necrophagous insects are very useful bioindicators in determining of post-mortem interval. The objective of this work was to determine the influence of seasons in the process of colonization by insects of a corpse exposed in the open air. Three pigs of 50kg each, were used as bait on each season in the sub-sudanese zone of C?te-d'Ivoire. Harvesting of adult insects was done by a filleting net. Samples of eggs, larvae and pupae were taken from the cadavers and then breeded in the laboratory. The insects collected were Coleoptera and Diptera. Three groups of insects were identified in the dry season and five in the rainy season. The the families of Calliphoridae, Muscidae, Sarcophagidae, Cleridae, Histeridae and Dermestidae were the first group in the two seasons appeared at fresh corpse, swelling and active decomposition. In both seasons, the 2nd group was composed of Cleridae, Histeridae and Dermestidae with the exception of Muscidae and Fanniidae, which were collected only during the rainy season. The 3th group was constituted of Tenebrionidae and Dermestidae in the dry season and Calliphoridae, Stratiomyidae, Piophilidae, Muscidae, Histeridae, Cleridae and Dermestidae in rainy season. These insects were captured during the active decomposition and advanced decomposition stages. The Piophilidae, Stratiomyidae, The appearance of Scarabaeidae and Tenebrionidae form the observed in advanced decomposition stages and skeletonization were the 4th group in the rainy season. The 5th group was composed of Piophilidae, Stratiomyidae, Dermestidae and Tenebrionidae. These insect families could serve as indicators in forensic entomology expertise.
