Dates are exposed to many insects pest in all its stages of maturity. Ephestia cautella is the major insect pest attacking dates at harvest time and storage particularly Siwy and Frihy cultivars. Five insecticides (tracer, radiant, coragen, pleo and achook) from new groups were selected as safe alternatives to human and environment against E. cautella in storehouse of Siwy and Frihy dates. Three concentrations of each insecticide (single, half and double concentrations) were sprayed on clean and untreated fruits of each cultivar for storing. The single concentration was a prescribed concentration, based on the recommended concentration to be used on different crops. Half concentration did not appear to be effective in all insecticides used on both cultivars, the double concentration was achieved 100% mortality during larvae stage period and single concentration was effective particularly in radiant while tracer was the lowest influence on insects. Data exhibited no significant changes in the main chemical composition of these treated dates. The residual levels of tested insecticides in the fruit were studied after 28 days from application
