Tanacetum abrotanifolium (L.) Druce (Asteraceae) ekstraktlarının Sitophilus granarius ile Sitophilus oryzae (Coleoptera: Curculionidae)’ye uzaklaştırıcı etkilerinin zorunluluk testleri ile belirlenmesi

Repellent effects of Tanacetum abrotanifolium (L.) Druce (Asteraceae) stem and flower extracts were tested against Sitophilus granarius (L.) (Granary weevil) and S. oryzae (L.) (Rice weevil) (Coleoptera: Curculionidae) under laboratory conditions. Repellent effects of plant extracts were tested in no-choice set up. The stem and flower extracts were obtained using three different solvents that were hexane, ethyl acetate, and methanol. In no-choice set up, the most pronounced repellent activity was seen with the stem ethyl acetate extract (58.96%) for the rice weevil and with the stem ethyl acetate extract (71.40%) for the granary weevil. These results indicate that T. abrotanifolium has a potential in the control of both S. granarius and S. oryzae especially in the grain stores .
