Abstract

The experiment was conducted to ascertain the efficacy of leaf powder of three botanicals (Azadirachta indica, Moringa Oleifera and Ocimum gratissimum) against Sitophilus granarius in stored wheat grains. Phytochemical screening of the leaves revealed the presence of flavonoid and phenol in Moringa, Alkaloids, flavonoids, Tannin, Glycosides and Saponin in A. indica while O. gratissimum contained Alkaloid, flavonoid, Tannin, Phenolic compound and Saponin. Adult S. granarius were cultured and exposed to different doses of the powder, 0g (control), 5, 10, 15, 20, 25 and 30g to assess their percentage mean mortality after 96hrs exposure. The result obtained showed that plant powder of M. oleifera recorded the highest percentage mean mortality of 93.33% after 96hrs exposure when compared with other treatments, followed by O. gratissimum (88.30%) then the least by A. indica (71.7%). The control (0g) does not evoke any weevil mortality. The leaf powder of M. oleifera evoked the highest percentage mean mortality. A. indica, M. oleifera and O. gratissimum had LD50 values of 4.40g, 2.70g, 3.00g and LD90 value of 32.40g, 9.80g and 10.80g respectively. It was concluded that the leaf powder of A. indica, M. oleifera and O. gratissimum could be used for the protection of stored wheat from S. granarius infestation.
