Abstract

The experiment lasted for a period of 3 weeks. The insecticidal property of Capsicum annum agamst Callosobruchus muculatus (cowpea weevil) was investigated in the laboratory. Mortality rate of cowpea weevil was tested using Capsicum annum at different grams ranging from 1g, 1.5g and 2g of the powder against 20 adult cowpea weevils. The experiment was carried out in replicates. The percentage mortality rates were 17.33 (86.65%), 18.00 (90.00%) and 19.69 (98.35/o) were observed after 2 weeks of subjecting the adult cowpea weevil to Capsicum annum of 1g, 1.5g and 2g. the efficacy of the plant powders on the emergence rate was also investigated within a period of 3 weeks. The values obtained within these weeks were analyzed in means, standard deviation and ANOVA. The mean and standard deviation values for plant powder were (28.67) (±1.155), (2.33) (±0.577) and (0.33) (±0.577). The values show significant difference at (P<0.05). It was observed that the powders reduced the emergence rate of weevil. Therefore, the plant powders should be used to protect stored cowpea from pest infestation.
