Abstract

Various neem products were compared with copra oil, palm oil and 0.25% diazinon dust for protection of stored maize against the grain weevil, Sitophilus zeamais Motsch. Maize kernels treated with neem oil or ash were damaged less than the control. Although copra and palm kernel oil reduced S. zeamais attack, these edible oils were not as effective as neem oil. Neem wood ash was however, less effective than 0.25% diazinon dust. Neem derivatives inhibited oviposition and/or deterred feeding.

Résumé

Les divers produits de neem etaient comparés avec (l'huile des noix de coco et l'huile de palme pour la protection du mais stocké, contre l'insecte Sitophilus zeamais Motsch. Des grains du mais traités avec de l'huile de neem ou la cendre du bois de neem étaient moins détruits que le contrôle. Bien que l'huile de copra et l'huile d'amende de palme ont reduit l'attaque de S. zeamais, ces huiles comestibles n'étaient pas éfficaces comme l'huile de neem. Cependant, la cendre de bois de neem, était moins éfficace que 0.25% de poudre de diazinon. Les produits tirés de neem ont empêché la ponte et l'alimentation.
