A research was conducted to test the efficacy of the powder of Aframomum melegueta, Cymbopogon citrates, Moringa oleiferaand Actellic Dust Insecticide against adult Sitophilus zeamais in stored maize grain. The various treatments were admixed with 10maize grain each and infested with adultweevil. 5, 10, 15, 20, 25 and 30g of the plant powder and 0.2g of synthetic powder/10grain was the ratio of mix. The treatments were kept in petri-dishes in an incubator for a period of 96hrs. The experiment was laid out in a completely randomized design of 8 treatments and 3 replicates. The mortality of weevils to the plant powders and the synthetic powder were recorded. Highest percentage mortality of 80% was recorded in the plant powder at 25 and 30g dose respectively. The highest weevil mortality percentage recorded at 25 and 30g in all the plant treatments coincide with that recorded in the synthetic powder. Maize was not affected by weevil at dose 20 and 30g likewise at 0.2g of the synthetic powder. The results of the study show that all the botanicals were effective in the treatment and prevention of maize weevil from invading stored-grain and their use should be advocated in prolonging the longevity of stored-product.
