Biological activity of four vegetable oils on Callosobruchus maculatus (Fabricius) (Coleoptera Bruchidae)
REDIA 87, 39-47
Abstract: The effectiveness of four vegetable oils - virgin olive oil, second pressing olive oil, oleaster oil and sunflower oil - has been evaluated on the longevity and the fecundity of adults and the embryonic and post-embryonic survival rate in Callosobruchus maculatus (Fabricius) (Coleoptera Bruchidae), under laboratory conditions. These oils reduce very significantly adult longevity when concentrations vary from 0.1 to 0.8 ml/50 g. No eggs were laid on Vigna unguiculata Linné (cowpea) seeds treated with second pressing olive oil at a concentration of 0.8 ml. Olive and oleaster oils reduced significantly the embryonic survival rate at a concentration of 0.8 ml/50 g. No adult emerged from seeds treated with olive and oleaster oils for nine months. The 3 major fatty acids found in these oils were palmitic acid, linoleic acid and oleic acid. The results obtained about longevity and fecundity of adults could be linked to fatty acids. The four oils do not affect germination of the cowpea seeds.
