ABSTRACT: The study on the effects of botanicals for the management of storage insects in beans was conducted at the plant pathology laboratory of the National Agricultural Research Institute (NARI) in The Gambia. The objective was to determine the most effective rate of neem leaf (Azadirachta indica) and pepper (Capsicum annuum) fruit powders in the management of Acanthoscelides obtectus on beans. The experiment was laid out in a Completely Randomized Design (CRD) with 10 treatments replicated five (5) times. A chemical called GRANOFORCE seed dressing chemical powder was used as the standard check, while the untreated was used as a control. The duration of the experiment lasted for 90 days. Data were obtained from the number of adult mortalities, the number of live insects, the weight of damaged seeds, the weight of healthy seeds, the number of seeds germinated, and temperature and humidity of the laboratory. There were significant differences among the treatments tested at p
