摘要

Certain plants by nature possess secondary metabolites, which act as antifeedants, oviposition deterrents, larvicidal and insect growth regulators (Vasantharaj David, 2008). It is known from literature sources that monoterpenes act as attractants/ repellants, whereas sesquterpenes and diterpenes exhibit considerable biological activity in relation to toxins and hormones produced by plants, many of which act as antifeedents. Alkaloids, coumarins, phenols, terpenes and polyphenols have antifeedant andgrowth inhibiting effects (Koul, 2005; Pavela, 2007). Such botanical pesticides are highly effective, safe and ecologically acceptable (Senthil Nathan and Kalaivani, 2005). Many plants belonging to Leguminosae and Solanaceae contain such as tomatin, chaconine, leptine, demissive, solanin etc., which act as feeding deterrents (Bennet and Wallsgrove, 1994; Ananthakrishnan, 1999).
