Abstract

Vegetable oil at a dosage of 1ml/kg bean seed, Phaseolus vulgaris (L.), showed insecticidal effectiveness against Zabrotes subfasciatus (Boheman) infesting stored beans. The active oil fraction appeared to be the triglyceride component. Oleic acid appeared to be the only effective fatty acid of the ones tested. Linolenic and arachidonic acid showed some insecticidal effect.
