Temporal Population Dynamics of Storage Insect Pests and their Management Using Safer Grain Protectants in Maize Smallholder Systems of Zimbabwe

Abstract: 
The study aims to determine peak flight activity periods and develop a safer and more efficacious grain protection strategies using different combinations of new and commercial diatomaceous earths (DEs), biopesticides and minimal pyrethroids against the major pests of stored maize over two storage seasons (2011/12 and 2012/13). The study also seeks to assess grain damage by resident versus incoming infestations. The treatment materials will initially be tested in the laboratory, and the best candidates will be further tested on-farm and onstation at the Institute of Agricultural Engineering (IAE) in Harare. Storage insect population dynamics through pheromone trap catches will also be conducted on-station at IAE.
L’étude vise à déterminer les périodes de pointe d’activité de vol et à développer des stratégies de protection des graines, plus sûres et plus efficaces, au moyen de différentes combinaisons de nouveaux insecticides et des insecticides diatomites commerciaux (DEs), les biopesticides et les pyréthroïdes minimales contre les principaux ravageurs du maïs stocké pendant deux saisons de stockage (2011 / 12 et 2012/ 13). L’étude vise également à évaluer les dommages des graines causés par des infestations résidantes par rapport aux infestations entrantes. Les matériaux de traitement seront d’abord testés dans le laboratoire, et les meilleurs candidats seront en outre testés à la ferme et à la station de l’Institut de génie agricole (IAE) à Harare. La dynamique des populationsd’insectes ravageurs de stockage à travers les captures par piège en phéromone sera également menée à la station de l’IAE.

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 Integrated Crop Management
