LC50 concentrations were measured after 24, 48, 72 and 96 hours, respectively. The SiO2 residues of traditional and their Nano particles were studied in leaves of mint, thyme, stems and soil, as well as the effect of drying and boiling techniques in the pesticide removal were also studied.</em>
<strong><em>The results indicated that</em></strong><em> the cumulative mortality rate of white fly and cotton aphid increased with increased pesticide concentration and/or increased time. The highest value of mortality in the tested insects was recorded in 96 hours of traditional SiO2 application. In case of silica Nano particles (SNPs), the highest mortality rate of white fly values were observed at concentration of 2.50 µg/ml after 48 hours of treatment. While, the same mortality value was observed at 2.50 µg/ml after 24h of treatment for A. gossybsii. These results indicate that A. gossybsii was more susceptible to silica and Nano-silica particles SNPs than B. tabaci and that the Nano-silica particles SNPs are more effective than the traditional silica.</em>
<strong><em>Conclusively,</em></strong><em> the results indicated that SiO2 of two forms plays the effective roles in integrated pest management and will be more effective when applied direct against white flies and aphis.</em>

The Sitophilus granaries was abundant in all months of studding, the rate of its infestation reach 28.5%. .Then, Sitophilus, zeamais, Sitophilus oryza 16.7%,and 13.9%, .The infestation rate decrease in Tribolium castanem, Sitotroga cerealell 11.5% and 9.8%, but Tyrophgus putresentiae and Dermatophagoids pteronyssinus available in few numbers 6.7% and 4.1%,. All pests increase in summer through July and august but when Spikes (Sanabil) was stored in a pottery pot, it did not get any pests during the study period. </em><br /> <em>The Tribolium castaneum was the most common infect the store wheat flour where the infestation reached 35.4% in July and August and decrease in December and January, then followed by the Lasioderma serrcon and Sitophilus granaries were infested reach about 22.4% and 15.The lowest incidence of infection emerged from Ephestia cauella and Corcya cephalonica were 3.5 ,1.9% consecutive.

<em>The obtained results showed that Arra 15 CV vines displayed the higher effect in most cases of their tested attributes compared with Arra 20 CV vines.
