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 (Azadirachtaindica) and pepper (Capsicumannuum) fruit powders in the management of Acanthoscelidesobtectus 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 < 0.05. The application of the botanical extracts significantly reduced the weight of damaged seeds, increased the weight of healthy seeds, and increased the rate of germination compared to the untreated (control). The results of the experiments revealed that all the treatments (plant powders and GRANOFORCE chemical powder) were toxic to the insect. The application of neem leaf powder at 70 grams significantly increased the mortality of storage insects more than all the other rates of the botanical extracts tested, except the application of neem at 60 grams in all the months. Similarly, all the rates of the botanical extracts increased mortality, reduced the number of living insects, reduced seed damage, and increased seed viability more than the control. None of the plant powders caused 100% mortality at 90 DAT. All plant powders, especially neem powder, at a considerable rate (at 70 grams) can be recommended to farmers for bean weevil control. The neem was more potent and was close to the standard check (GRANOFORCE chemical powder) and can be used in the integrated pest management of bean weevil in storage.
