Özet

In this study, insecticidal effects of the essential oils obtained from plantsOcimum basilicumL.,Rosmarinus officinalisL. andArtemisia dracunculusL. on confused flour beetle (Tribolium confusumdu Val., 1863 (Coleoptera: Tenebrionidae)) and bean weevil (Acanthoscelides obtectus(Say), 1831 (Coleoptera: Bruchidae)) adults were tested in laboratory conditions. In this context,T. confusumandA. obtectusadults were exposed to essential oils at 10 and 20 mu L/petri doses for 24, 48, 72 and 96 h. All of the essential oils used in the study caused mortalities at different rates in two application doses but end of the 96 h all mortality rates were obtained similar (O. basilicum98.3%,R. officinalis98.3%,A. dracunculus93.3% againstT. confusumadults; O. basilicum100%,R. officinalis100%,A. dracunculus100% againstA. obtectusadults). It was determined that the effects of essential oils onA. obtectusadults were greater thanT. confusumadults. Especially when the dosage was 20 mu L, the death rate increased up to over 95% after 96 h for all types. The mortality rates increased with increasing exposure period at the 48, 72 and 96 h. in all applications. The results of the study suggest that essential oils fromO.basilicumandR.officinaliscould have a potential as control agents againstA. obtectusandT.confusumadults under storage conditions.
