Amorphous silica dust (Oryacide) was used to control adults of Sitophilous granarius at concentrations of 200, 400, 600, 800 and 1 000 ~g silica dust/g wheat. Adults of S. granarius were placed in the three classes of wheat grains (hard, soft & durum)and incubated at 20°C and 28 ± 1 °C and 65 ± 5 % R.H. Mortality counts were estimated after 48 and 168 hrs. Toxicity increased with increase
lower concentration and temperature. Percent reduction of progeny reached 66.66 - 75.0 % in some wheat classes. Silica dust gave high percentages of mortality after long-term storage at the four periods (1, 8, 16, and 24 weeks) at 500 and 1000 ~g/g w. Seed germination was not affected by treatment by silica dust.
