Abstract
Studies were carried out to examine the insecticidal properties of powdered extract of four (4) plant species namely, Allium sativum (L.) (bulb); Drimia maritima (L.) (Baker.) (bulb); Erythrina senegalensis (L.) (stem bark); and Khaya senegalensis (Desr.) (stem bark) against maize weevil (Sitophilus zeamais Motschulsky) infestation on stored maize (Zea mays).The efficacies of the plants powders at four (4) levels of concentration of 0.5g; 1.0g; 2.5g; and 5.0g on maize weevil (Sitophilus zeamais Motschulsky) mortality monitored over 24hrs, 48hrs, 72hrs, and 96hrs intervals were assessed and compared to the industrially formulated insecticide, Coopex (Permethrin 0.5%) using standard method. Results obtained revealed that powdered extract of the four (4) plants species evaluated showed varying degree of efficacies at certain levels of concentration. The infested maize grain treated with bulb powder of Allium sativum (L.) and stem bark powder of Khaya senegalensis (Desr.) proved to be the most efficacious with recorded Lethal Dose (LD50) 0.07g and 0.08g, respectively after 24hr. Bulb powder of Drimia maritima (L.) (Baker) and stem bark powder of Erythrina senegalensis (L.) had Lethal Dose (LD50) of 5.10g and 0.20g, respectively after 24hr. On the strengths of these findings it is evident that Allium sativum (L.) and Khaya senegalensis (Desr.) are potential plant materials for bio-control of maize weevil (Sitophilus zeamais Motschulsky) infestation on stored maize grains.

Key words: Sitophilus zeamais, Allium sativum, Drimia maritima, Erythrina senegalensis, Khaya senegalensis and Maize, grain storage.
