Ecology and Safer Management of Storage Insect Pests in Sorghum Smallholder Farming Systems

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.
Cette étude vise à développer des alternatives sûres, efficaces et respectueuses de l’environnement aux insecticides conventionnels à base d’organophosphates et à générer une meilleure compréhension de la dynamique des populations d’insectes ravageurs des greniers afin d’identifier les mesures appropriées pour lutter contre ces ravageurs. Trois expériences seront réalisées:les bio-essais en laboratoire, les études d’efficacité sur le terrain et les études écologiques. La mortalité des insectes, les dommages du grain et la teneur en eau des grains, les espèces d’insectes et leur spectre seront évalués afin de déterminer l’efficacité et la persistance des protecteurs. Concernant les études sur l’écologie, la dynamique des populations et l’efficacité de l’exclusion des insectes sur les dommages du grain seront déterminées et celles-ci donnerontun guide pour savoir quand les protecteurs des céréales peuvent être appliqués.

The 2012 RUFORUM Biennial Conference is the third in the series. The main objective of the Biennial conferences is to provide a platform for agricultural research for development stakeholders in Africa and beyond to actively exchange findings and experiences, while at the same time learning lessons towards improving performance of the agricultural sector and ultimately people’s livelihoods. The biennial conference is RUFORUM’s most comprehensive meeting for the diversity of stakeholers in agriculture. It is especially dedicated to graduate students and their supervisors, grantees in RUFORUM member universities and alumni. It is a platform for peer review, quality control, mentorship, networking and shared learning. The third Biennial Conference was attended by 657 participants.This record contains an extended abstract accepted under the theme of Integrated Crop Management
