Dusting of polyethelen and jute sacks with Fenitrotion 1%, Deltamethrin 1% and Bendiocarb 0.1% at the rate of 500 and 1300 mg/m2 using Manual duster were carried out and stored in open shaunas up to 3 months in Ismailia and Gharbia governorates to evaluate the persistence against 4test insects (sitophilus oryzae(L.), Rhizopertha dominica(F.), Trogoderma granarium Everst and Tribolium castaneum (Herbst) adults. Considering pest mortality and germination. Results indicated that :- - Tested insecticides were more persistence on polyethelen sacks than on Jute fabrics. - Protection of stored wheat graing was more succeesful in Ismailia governorate than in Gharbia governorate at all storage periods and tested doses. - Fenitrothion insecticide was more effective in moiety in killing tested insects on the two doses and experimental sacks at the two governorates. It gave complete protection (100%mortality) With high dose (1300mg/m2) using polyethelen sacks for the three storage months, in Ismailia governorate However, gradual decrease in protection was occured when using Jute sacks (70/mortality) - Residual efficiency of bendiocarb at 1300 mg/m2 was the least, it gave a complete protection of grain (100% mortality) for one month only in the two governorate, and decreased after 2 and 3 on months in polyethelen sacks showing 81%, 70% and 79%, 74% in Ismailia and Gharbia governorates, respectively whereas, sharp decrease of efficiency was detected with Jute sacks, it gave 19% and12% mortality after 3 months in the tested governorate, respectively . - Deltamethrin insecticide gave intermediate in its efficiency on both tested sacks and doses in the two governorates . - The treatments did not impair the germination of seeds under various treatments at the two tested governorates.
