In Niger, considerable damage is recorded on seed legumes during their storage. For this, chemicals are used for the preservation of these foodstuffs. The objective of this study is to understand the use of storage insecticides against pests in Cowpea. A survey was carried out using structured sowing questionnaires with 404 producer heads of households in 16 target villages.The study shows that 91.8% of operators use insecticides for the conservation of cowpeas, mainly approved products (76%), namely Phostoxin (55.94%), Justoxin (16.58%), Rambo (0, 50%), Lamda super 2.5 EC (1.73%), Calthio (0.99%) and non-approved products (16%), namely Executor (5.20%) and Superdelvap (10.89%). This use of chemicals varies depending on the Regions (Dosso, Tillaberi, Maradi).Thus, the study also showed that 65.1% of households use phostoxin in the Dosso region compared to 29.5% and 63% respectively in the Maradi and Tillabéri regions. Up to 40% of producer households use super delvap, which is an unauthorized product to prevent damage of [Callosobruchus maculatus (Fab.)] From Cowpea at Maradi.

Abstract: (french)
Au Niger, des dégâts considérables sont enregistrés sur les légumineuses à graines pendant leur stockage. Pour cela, des produits chimiques sont utilisés pour la conservation de ces denrées. L’objectif de cette étude est d’appréhender le mode d’utilisation des insecticides de stockage contre les bioagresseurs de Niébé. Une enquête a été réalisée en utilisant les questionnaires semis structurés auprès de 404 producteurs chefs des ménages dans 16 villages cibles.L’étude fait ressortir que 91,8% des exploitants utilisent des insecticides dans la conservation du Niébé principalement les produits homologués (76%) à savoir Phostoxin (55,94%), Justoxin (16,58%), Rambo (0,50%), Lamda super 2.5 EC (1,73%), Calthio (0,99 %) et les produits non homologués (16%) à savoir Executor (5,20%) et Superdelvap (10,89%). Cette utilisation des produits chimiques varie en fonction des Régions (Dosso, Tillaberi, Maradi).Ainsi, l’étude a aussi montré que 65,1% des ménages utilisent le phostoxin dans la Région de Dosso contre 29,5% et 63% respectivement dans les Régions de Maradi et de Tillabéri. Jusqu’à 40% des ménages producteurs utilisent du super delvap qui est un produit non homologué pour prevenir les dégats de la bruche [Callosobruchus maculatus (Fab.)] de Niébé à Maradi.
