Abstract
In this study efficacy of essential and fixed oil of Laurus nobilis L., on controlling Aphis fabae Scopoli that grows on Vicia faba L. (Fabaceae) has been studied by experiments set up in the laboratories of Çukurova University Biology and Plant Protection Departments in 2016-2017. Fixed oils had previously been found to be effective on aphids according to death rate and Abbott test values, but they had also phytotoxic effects on plants. Therefore, the essential oils were preferred in the present study. In essential oil solution applications (prepared with hexane and glycerol monostearate), 100 µL mL-1 and overdoses caused significant phytotoxicity and according to the results hexane significantly caused the death of aphids, therefore, the study was continued without the use of hexane. The effects of hexane-free solutions prepared with glycerol monostearate were found statistically differences (p
