Abstrakt: A storage experiment was conducted in Bante, central Benin between autumn 1994 and spring 1995. The maize was harvested 1, 3, and 7weeks after physiological maturity and stored for up to eight months. The main results were: (a) Leaving the maize in the field for extended periods after physiological maturity resulted in severe grain losses after eight months of storage; (b) Most of the grain losses were attributed to Prostephanus truncatus; (c) Early harvested maize had a higherproportion of mouldy grain; (d) Harvest date had no consistent effect on the level of aflatoxin contamination; (e) Based on a participatory evaluation of maize quality by local farmers, the economic value of maize stored for eight months was highest in maize harvested three weeks after physiological maturity.
