Description Background: Storage pests cause extensive damages to stored products and are responsible for huge post-harvest losses affecting the quality, the quantity, and the germination potential of stored grains and seeds. This study aimed to investigate the variability of traditional methods of storage and conservation of maize seeds practised by farmers to propose alternative measures for a significant reduction of post-harvest losses of seeds. Methods : Using participatory research approaches, we surveyed farmers from 21 randomly selected villages in 5 districts in southern Benin. Data were collected on the storage structures of the 3 certified and most produced maize seeds varieties. The forms under which maize seeds are stored, as well as the damage caused by the major storage insects were determined. Results: Results showed that most farmers store maize seeds in the form of grains and spathe. Following the laboratory observation of the three maize varieties studied, the DMR / QPM variety produced only in the district of Zagnanado has a low abundance of storage insects and a low rate of post-harvest losses. Sitophilus zeamais is the most abundant pest of the three maize seed varieties followed by Prostephanus truncatus. The variety 2000 SYN EE was the most attacked by storage insects. The most promising post-harvest agricultural practice is the storage of maize with spathe saved in jute bags, in granaries or cribs. Conclusions: Storage insects contribute to the depreciation of the quality of grains, loss of grain and reduction of their germinability in stock. Improving farmers awareness of these post-harvest practices could help to reduce the damage of storage insects. (2022-03-24)
