Abstract– Plant products in form of essential oils may serve as suitable alternatives to synthetic pesticides for repellent and antifeedant activity. In the present investigation Citrus limon leaf and peels oil were used for insecticidal activity. The maximum percent repellency (PR) was recorded 100% at 16μl of C. limon leaf and peel essential oil respectively against stored-grain insect pests Sitotroga cerealella. The consumption by third instar larva was significantly reduced to 68.12% and 59.64% of the control against C. limon leaf and peel oil respectively. These studies showed strong insecticidal activity of both essential oils and its potential role as a fumigant against S. cerealella for future as they are relatively safe, inexpensive, and are readily available in many parts of the world.
