The present study, which aims to contribute to the valorization of Capsicum chinense, focuses on ethnobotanical investigations and evaluation of insecticidal activity on Sitophilus zeamaïs and Aphis craccivora, as well as the germination power of infected maize and peanut grains treated and not treated with Capsicum chinense leaf powder. To do this, the moisture content of corn and peanuts was determined by the techniques: drying in the sun and in the oven. The insecticidal effect of the powder was tested on maize and peanut kernels infected by the AGRAR (2013) method, followed by a test of the germination potency of these treated grains. The average moisture values of corn and groundnut kernels are 14.51% and 12.25% respectively. The results show, a higher insecticidal efficacy of Capsicum chinense leaf powder on Sitophilus zeamaïs and Aphis craccivora with doses (2, 4 and 8 g). The average germination rates of maize and peanut kernels infected and treated with this powder are: (16.5%; 63%; 99.5%) and (21.25%; 96.5%; 99.75%), respectively. This study could be a bio-insecticide alternative for the peasant community in the conservation of cereal and legume products.
