In Burkina Faso, the food post- harvest conservation remains a major constraint. A survey to understand farmers' perceptions of post-harvest conservation of cowpea and Bambara groundnut was carried out in nine villages of Hauts-Bassins. This survey was followed by an evaluation of samples taken from stocks of these legumes. The results show that farmers retain their crops of Bambara groundnut and cowpea at home in bags, sealed and unsealed devices. The use of traditional methods is the most widespread. According to farmers, the insects are responsible for the essential of post-harvest losses of legumes. Laboratory analysis of the samples collected, helped to identify six (6) insect species distributed in the orders of Coleoptera and Hymenoptera. Callosobruchus maculatus Fab. and Callosobruchus subinnotatus Pic. are the most abundant species. Knowledge of post-harvest strategies in a traditional rural environment is an essential prerequisite for the development of methods and structures for effective protection of stored products. Such knowledge opens the way for the definition of methods for detection of infestations and loss estimation, the recommendation of rational methods of control, preventive as well as curative.

Abstract: (french)
Au Burkina Faso, la conservation post-récolte des denrées alimentaires demeure une contrainte majeure. Une enquête visant à appréhender la perception paysanne de la conservation post récolte du niébé et du voandzou a été réalisée dans neuf villages des Hauts-Bassins. Cette enquête a été suivie d’une évaluation d’échantillons prélevés dans les stocks de ces légumineuses. Les résultats montrent que les producteurs conservent leurs récoltes de voandzou et de niébé à la maison dans des sacs, des dispositifs hermétiques et non hermétiques. L’utilisation des méthodes traditionnelles est la plus répandue. Selon les producteurs, les insectes sont responsables de l’essentiel des pertes post-récoltes des légumineuses. L’analyse au laboratoire des échantillons collectés a permis d’identifier six (6) espèces d’insectes répartis dans l’ordre des Coléoptères et des Hyménoptères. Callosobruchus maculatus Fab. et Callosobruchus subinnotatus Pic. sont les espèces les plus abondantes. La connaissance des stratégies post-récolte en milieu paysan est un préalable indispensable à la mise au point de méthodes et de structures permettant une protection efficace des produits stockés. Une telle connaissance ouvre la voie à la définition de méthodes de détection des infestations et d'estimation des pertes, à la recommandation de méthodes rationnelles de lutte préventives aussi bien que curatives.
