The Efficacy of <em>Xylopia Aethiopica</em> and <em>Piper Guineense</em> Seeds Powder on <em>Sitophilus Oryzae</em> Mortality

Abstract

Efficacy of Xylopia aethiopica and Piper guineense seeds powders in the control of Sitophilus oryzae was investigated. In the laboratory experiment, the Xylopia aethiopica and Piper guineense seeds powders were applied at rates of 0gm (control), 10gm, 25gm, 50gm, 100gm kg^-1 respectively for the control of Sitophilus oryzae. Xylopia aethiopica and Piper guineense seeds powders at the rates of 100gm kg^-1 respectively were found to having effective potentials in the control of Sitophilus oryzae. Piper guineense seed powder from the experiments conducted were generally more efficacious as having the potentials in the control of insect pests as seen in tables 1-3 of this study.
