Abstract

This paper, which discusses the current status of conventional insecticides in the management of stored product insect pests in the tropics, shows that insect infestation in stored products is high in the tropics and may lead to 100% damage in severe cases. Conventional insecticides used in their management, such as permethrin, lindane, pirimiphos-methyl, phostoxin, methyl bromide and io-dofenphos, and their methods of application are also discussed.

Methods of storing grains and other grain products are inadequate and in most cases reduce the efficacy of insecticides thereby enhancing the multiplication of the insects. The problems associated with insecticide usage in disinfesting stored products are highlighted and suggestions are made for their solutions.

Résumé

Cette étude qui adresse le statut actuel des insecticides conventionnels dans la gestion des reserves de produits d'insectes nuisibles dans les tropiques révèle que l'infestation par des insectes de produits de reserve est élevé dans les Tropiques et que ceci peut atteindre, dans certains cas graves un niveau de dégats de 100 pour cent. Les insecticides conventionnels utilisés dans la gestion de ces produits et qui comprenuent le permethrin, le lindane, le pirimiphos-methyl, le phostoxin, le methyl bromide et l'iodofenphos ainsi que leurs méthodes d'application sont également discutés.

Les méthodes de conservation des grains et des produits de grains sont insuffisantes et dans la plupart des cas réduisent l'efficacité des insecticides ainsi promouvant la multiplication des insectes. Les problèmes qui s'associent à l'usage de l'insecticide dans la desinfection de produits en conservation sont soulignés de même que des solutions à ces problèmes sont suggérées.
