A laboratory study with the objective of investigating the effects of neem seed and leaf powder against adult bean weevil was
conducted at an animal research laboratory. The study had one factor neem seed powder at rates of 2, 4 and 6% w/w and
control group and another factor of neem leaf powder at rates of 2, 4 and 6% w/w and control group. The treatments were
applied with three replications. Data were collected on dead adult weevils only. The dead adult weevils were counted within 7,
21 and 42 days after the infested bean was treated by neem seed powder and leaf powder. The collected data were subjected to
one way ANOVA procedures. Results showed that there were significant differences (p<0.05) in the mean percent mortality of
A. obtectus among the different concentration of seed and leaf powder with time of storage. The highest mean mortality
percent were recorded at the 6% w/w concentration. The 2, 4 and 6% w/w concentration rates of neem seed powder killed
about 68.39, 73.6 and 87.15% of adult weevils, respectively throughout the storage period. Whereas the leaf powder treatment
killed 66.17, 70.28 and 82.57% adult weevils respectively. It is concluded that the application 6% w/w of both neem seed and
leaf powder are effective in the control of bean weevil and could be used as an alternative control option in integrated stored
pest management strategies by small scale farmers.
