Abstract

This study was carried out to evaluate toxicity and residual effect of chemical insecticide deltamethrin, biological insecticide Beauveria bassianaa and phosphate fertilizer. This Evaluation was conducted against Callosobruchus maculatus (F.) adults and Rhyzopertha dominica (F.). Results indicated that biological insecticide was the most effective material that still kills adults of C. maculatus and R. dominica till the end of the storage period (3months). The chemical insecticide caused a complete death for C. maculatus adults till the end of the storage period while it decreased with time for adults of R. dominica. All treatments did not affect seed germination and water absorption.
