This study was conducted to observe the effects of dried tobacco leaf smoke on controlling aphids in a laboratory and a greenhouse. Insecticidal activity of tobacco smoke against Aulacorthum solani in an acrylic cage was higher when a burley cultivar, rather a flue-cured cultivar, was used. Mortality of A. solani, Aphis gossypii, and Myzus persicae was 63.9%, 94.4%, and 97.2%, respectively, after 50mg of tobacco smoke on their host plants in an acrylic cage. Mortality of M. persicae after tobacco smoke was used was higher in eggplant than in Chinese cabbage. When 100 g and 200 g of flue-cured tobacco were smoked in a $100m^2$ greenhouse for 2 h, the control values against A. solani were 28.9% and 95.4%, respectively; the control value after 14 h of smoking was more than twice the value after 2 h of smoking. The control value against A. gossypii was more than 80% after tobacco smoke was used in a greenhouse in an organic cucumber farm. Tobacco smoke can be an effective control against aphid pests in greenhouses if an appropriate amount of tobacco and smoking time on the basis of the greenhouse conditions are used.
