Most packaged food products are attacked and penetrated by insects. Causing reducing food quality. Since, different ways are investigated for controlling stored-product pests without application of chemical methods. So, the present study included laboratory methods to evaluate the effectiveness of two packaging materials, polyethylene and cellophane with silica nano particles to prevent or minimize the insect infestation and grain wastage resulting by the attack of wheat grain by confused flour beetle, Tribolium confusum. Studies made to determine the protecting capacity of the two packaging materials through assessing some parameters, number of adults infested poly ethelene and cellophane bags, percentage weight loss of grains, the results revealed that cellophane was the better packaging material than polyethelene, so polyethylene was the susceptible packaging material because it had maximum number of holes as a result penetrations by insects into them. Also, treatment the two types with packaging materials with different concentrations of nano silica protect the treated packaging materials from insect infestation and the protection increase with the increase of the concentration of silica nano particles

大多数包装食品都会受到昆虫的攻击和渗透。导致食品质量下降。因此，人们研究了在不使用化学方法的情况下控制储藏害虫的不同方法。因此，本研究采用实验室方法来评估两种包装材料（聚乙烯和带有二氧化硅纳米颗粒的玻璃纸）的有效性，以防止或最大程度地减少由于混淆的谷盗（Tribolium consumum）攻击小麦谷物而造成的昆虫侵扰和谷物浪费。研究通过评估聚乙烯和玻璃纸袋成虫侵染的数量、谷物失重百分比等参数来确定两种包装材料的防护能力，结果表明，玻璃纸是比聚乙烯更好的包装材料，因此聚乙烯是最好的包装材料。易受影响的包装材料，因为它有最多数量的孔，导致昆虫侵入。此外，用不同浓度的纳米二氧化硅处理这两种类型的包装材料可以保护处理过的包装材料免受昆虫侵扰，并且随着二氧化硅纳米颗粒浓度的增加，保护作用增强
