One alternative to manage insect resistance to insecticides is through the use of botanical insecticides such as leaf extract of tobacco (Nicotiana tabacum) which has long been used for insect control. Tobacco leaves contain nicotine as the main active component, which was isolated in 1828, and the potency of nicotine is already well recognized (Gilbert, 2011). Sohail et al. (2012) report that tobacco water leaf extract at a concentration of 2% was effective against aphid, Toxoptera aurantii and Khapra, Trogoderma granarium (Sarmamy et al. 2011).
