Abstract

104 words

This study seeks to develop safe, effective and environmentally friendly alternatives to the conventional organophosphate-based insecticides and generate better understanding of storage insect pest population dynamics so as to identify appropriate measures for controlling the pests. Three experiments will be carried out; laboratory bioassays, field efficacy studies and ecological studies. Insect mortality, grain damage, grain moisture content, insect species and spectrum will be assessed to determine efficacy and persistence of the protectants. In the ecology studies; population dynamics and the effectiveness of insect exclusion on grain damage will be determined and these will give a guide as to when grain protectants can be applied.
