Description

Byline: Salih Karaborklu, Abdurrahman Ayvaz and Semih Yilmaz Abstract.- In this study we have tested fumigant toxicity of ten aromatic plant essential oils on red flour beetle, Tribolium castaneum, and bean weevil, Acanthoscelides obtectus, under laboratory conditions. The plant samples were collected from different sites of Turkey, air dried at room temperature and the essential oils were obtained by steam distillation, using a Clevenger-type apparatus. Laurel and myrtle essential oils showed strong fumigant activity against A. obtectus and T. castaneum adults at different concentrations. Estimated LC50 and LC99 values for A. obtectus adults were 45.31 and 70.75 ul/l air for myrtle, 27.36 and 43.05 ul/l air for laurel or tansy oils, respectively. The T. casteneum were more resistant to myrtle and laurel than A. obtectus and lethality values were estimated as 92.80 (LC50) and 159.03 (LC99) ul/l air for myrtle 56.98 and 89.73 ul/l air for laurel oils, respectively.
