Cowpea weevil (Callosobruchus maculates) is a serious Cowpea pest which affects and destroys severely the grain within short period of 6 month in an open field and during storage period. This study aimed to evaluate the performance of hot pepper, black pepper, ginger and Moringa powder extracts and two storage methods against cowpea weevil. Laboratory experiment was conducted at plant protection laboratory of the faculty of Agriculture and Environmental Science-Somali National University during 15 June - 25 December, 2019. The design of experiment was laid out in completely randomized design (CRD) with five treatments and three replications. Hot pepper, black pepper, Moringa and ginger powders extracts at the same concentration of (4 gram) were applied on 20 insects in 100 gram of local cowpea variety as primary host for cowpea weevil. Meanwhile, two comparative storage methods of traditional and modern methods have been used to store 10 kg of cowpea in each method. The results indicated that all powder treatments were effective against cowpea weevil compared to the untreated control. Significant different at p<0.05 in the mean number of insect pests were found. The study showed that 4gram of each hot pepper and black pepper was the most effective one among the selected natural products in reducing the number of weevils at mortality number of (%100) insects/jar compared to the other concentration as well as control treatment. A significant difference of weight losses was observed between treatments, where the 4gram of hot pepper and black pepper were recorded the lowest level of weight loss at the mean numbers of (4.3, 5) insects/jar respectively comparing to the other treatments. On the other hand, hermetic storage was the most effective in reducing the pest infestation and weight loss of cowpea. This study recommended that applying; 4gram of each hot pepper and black pepper and using a hermetic storage reduce the number of cowpea weevil in cowpea grain.
