The pests of stored products, are one of the factors effecting quantity and quality of foods during their storages. Plant based insecticides are new compounds that can control insect pests without negative effect on environment and food safety. This study had done in order to investigate effect of essential oil of Cichorium intybus and Utrica dioica in different treatment duration (24, 48 and 72 hours) on mortality of larval and adult stages of Oryzaephilus surinamensis. The experiments were done at entomology laboratory of Islamic Azad University of Tabriz during 2018, based on a complete randomized design in 25±1 °C and 60±5% of humidity. Investigation had done in 4 replications and 25 insects per unit. Based on LC50 value from probit analysis of mortality percent least LC50 value to Oryzaephilus surinamensis obtained in adult insects and by essential oil of C. intybus Highest LC50 value also belong to larval stage with essential oil of this plant. Results of line-effects showed that in C. intybus essential oil mortality of larval were more than adults. But essential oil of U. dioica caused different changes and adult insects showed more sensitivity to U. dioica essential oil than larvae of pest. The results detected that essential oil of C. intybus and U. dioica had a suitable control on O. surinamensis.
