Abstract
Laboratory experiments were conducted to assess infection potential of C. maculatus (F.) (Coleoptera : Bruchidae) on four cowpea and faba bean varieties stored for 6 months. Infestation rates, loss in seeds weight and number of emerged beetles were the criteria used to assess the vulnerability of cowpea and faba bean to post-harvest Infestation. Cowpea local variety and faba bean Giza 843 showed a slight degree of resistance to insect infestation, therefore they can be stored safely for a relatively long period (6 months) with lowest rates of infestation and weight losses of stored seeds. The effect of store controlled temperatures 25°, 30° and 35°C 2°C on seed consumption, seed damage and losses of different cowpea and faba bean varieties was investigated. Results revealed that all the former parameters significantly (P > 0.05) decreased by the increase of store temperature. So, high temperature of 35°C or above can be used as an environmental element to store cowpea and faba bean seeds safely with the least damaged and losses of stored seeds for approximately 6 months.
