The component of important ancient Herbal, Ferula assafoetida contains sulphur compounds and trepans derivation. This plant was used as natural insecticide against Lepidoptera and homoptera in the Iran. In the current study, the effects of F. assafoetida on the adults of Tribolium confusum were evaluated. The few sap of plant was transferred to university of Birjand from Kerman province. Extract of saps were prepared using ethanol 90 percent and diluted with acetone. Adults (72 hours olds) of T. confusum were selected from insectary room in the entomology laboratory. Final concentrations were 0, 20000, 40000, 60000, 80000 and 100000 ppm. Experiments were performed in the three replications and used from acetone as control treatment. Results showed that 20000 and 40000 ppm were not significantly difference in comparison to the control. The difference among two concentrations 60000 and 80000 ppm with 43 and 55 percent of mortality with control was siginificant. The highest mortality was appeared in the 100000 ppm. Results suggest that only 100000 ppm is appropriate dose to recommendation against T. confusum. The economic importance of F. assafoetida is open discussion to evaluate using of its extract against store pests.
