Abstract

Cette invention concerne une composition insecticide comprenant un mélange d'un liant polymère et d'une suspension d'un ou de plusieurs entomopathogènes. Le mélange comprend, en outre, une substance huileuse dans un rapport au liant polymère permettant la migration des entomopathogènes hors de ladite composition. Dans un mode de réalisation préféré de la composition, l'huile est mélangée avec les agents entomopathogènes et un enrobage à base d'alcool polyvinylique (PVA) est préparé à partir dudit mélange. La composition peut être pulvérisée sur une moustiquaire ou un filet, ou un vêtement, ou directement sur les surfaces visitées par les insectes nuisibles pour que l'agent entomopathogène les détruise avant qu'ils ne puissent infecter des êtres humains ou le bétail avec des pathogènes provoquant des maladies ou ne provoquent des nuisances.
