Control of insects in stored products is very important. Sitophilus granarius (Linnaeus, 1758) (Coleoptera: Curculionidae) and Tribolium castaneum (Herbst, 1797) (Coleoptera: Tenebrionidea) are two important insect species that cause damage to stored products. The need for alternative drugs that can be used to control of pests in stored products is increasing day by day. In this study, the usability of plant extracts obtained from Achillea phrygia Boiss. et Bal.(Compositae), Prangos ferulacea (L.) Lindl. (Apiaceae) ve Salvia wiedemannii Boiss. (Lamiaceae) plants to control S. granarius and T. castaneum were investigated. At the end of 72 hours, the highest contact activity among the plants tested on S. garanarius showed P. ferulaceae hexane with 74% and A. biserrata methanol extract with 71%, respectively. The highest activity on T. castaneum was obtained by A. biserrata ethyl acetate extract at 42% after 72 hours. On the other hand, the highest repellent activity on S. granarius was obtained from P. ferulaceae ethyl acetate extract (52%) after 24 hours. All plant extracts showed high repellent effect on T. castaneum.
