Abstract

Four petroleum fractions extracts from solar, lubrication oil, kero­sene and paraffin oil were treated on certain glass, polyethylene and cotton fabric (Dammur) to evaluate their efficiency and persistence against adults of Callosobruchus maculatus F. for different periods ex­tending up to six months. Results revealed that the persistence of frac­tions on different surfaces had differed according to the type of surface used. Solar fraction was the most persistent followed by kerosene, lubri­cation oil then paraffin oil. Glass surface was the most ideal to retain toxicity followed by polyethylene and cotton fabric (dammur).
