This study was conducted during the period from December 2021 to February 2022 in the Dakar area. It was conducted to contribute to the inventory of acarofauna, entomofauna and nematofauna of imported or local cereals in Senegal. In this context, sampling was carried out in the markets of Sandaga, Tilène, Gueule Tapée and in village Diofior village. Thus, out of 16 samples of incubated cereal varieties, observation and identification of specimens obtained after sorting and extraction revealed the only presence of insects; mites and nematodes were not found in our stocks. Insects were composed of 961 specimens belonging to the Order Coleoptera (42.87%) with eight species Oryzaephilus surinamensis (14.98%), Cryptolestes ferrugineus (11.86%), Rhyzoperta dominica (8.63%), Sitophilus oryzae (5.20%), Tribolium castaneum (1.87%), Prostephanus truncatus, Carpophilus sp. and an unknown species (0.10%); the Order Lepidoptera with a single species Ephestia cautella (50.05%); the Order Psocoptera (5.93%), the Order Hymenoptera (0.72) and the Order Hemiptera (0,41). The species found in the last three orders were not identified. Results obtained showed that the local cereals are much more contaminated than imported ones. In addition, it also revealed an important diversity of insects in imported cereals, with a much more marked similarity between Senegal-Mali and China-Thailand.
