1993 Two rates ( 5 & 10 ppm a.i. ) of chlorpyrifos-methyl were applied to wheat grains, stored in tightly-closed glass jars ( each 5 L capacity ) under the laboratory conditions for 12 months . Insecticide residues and its insecticidal activities were evaluated at different intervals. The results showed that, the percent losses in chlorpyrifos-methyl after 12 months were 52.81 % and 59.11 % for the lower and higher rates, respectively, without any insecticidal activity to the insects : Trogoderma granarium and Tribolium confusum . The degradation pattern of the insecticide was triphase with t 0.5 = 34 weeks.Al-Rajhi, D. H; A. Tag-EL-Din; H. I. Hussein; S. Mostafa
