The purpose of the study was to determine influence of natural essential oils, i.e. coriander and petitgrain oils on mortality of foxglove aphid (Aulacorthum solani Kalt.) occurring on tobacco. The above mentioned oils were used at the concentration of 0.02, 0.05 and 0.1%. The mortality of pest was evaluated 24, 48 and 72 hours after treatment. Natural essential oils such as coriander oil and petitgrain oil may be useful in the control of foxglove aphid (A. solani). After application of these oils mortality of the pest was significant and amounted to 81.20–99.47% and 89.80–99.50%, respectively (72 hours after treatment).
