Abstract

The petroleum oil fractions, kerosene, solar and a lubricant were tested against Sitophilus oryzae L. infesting grains . The residual effect of such oil fractions was also studied . Results showed that the medium fraction (solar) produced higher residual effect than the lower (kerosene) and the higher fraction ( lubricant ). Rate of 15m1 fraction/ kg ‘kheat could be recommended for the control of S. oryzae ( L.) in wheat grains. This dose gave 100% mortality up to 20 weeks after treatment. for kerosene, 22 weeks for solar and 18 weeks for the lubri­cant. Grain germination was not affected by oil treatments.
