Abstract: Acetone extracts of plants Azadiarachta indica (neem), Citrullus colocynthus (Tuma), Moringa oleifera and new chemistry insecticides emamectin benzoate and thiamethoxam at a concentration of 5 %, 10 %, and 15 % were evaluated for their repellent and mortality effect against Cryptolestes ferrugineus. The results showed that maximum percent repellency (90%) was achieved in plant extract of Azadiarachta indica at a concentration of 5 % after an interval of 72 hours, while minimum percent repellency (3.03%) was recorded in plant extract Moringa oleifera after an interval of 72 hours at a concentration of 15%. Maximum mean mortality (78.43 %) was recorded in Thiamethoxam at 15% concentration after an interval of 72 hours and minimum mean mortality (5.08 %) was recorded in plant Moringa oleifera after an interval of 24 hours at 5 % concentration. From these results it was concluded that plant extracts are more effective as repellent while new chemistry insecticides had high toxic effects as compared to plant extracts against Cryptolestes ferrugineus
