Pesticidai efficiency of the mineral oil CAPL-2 at 1.5 , 0.75% and Organophotiphorous pesticide, actellic at full (385 cm³ / 100L) and 1/10 (38.5cm³ /100L) recommended rate and for the mixture of CAPL-2 at 0.75% + actellic at 1/10 (38.5cm³ /100L) recommended rate were determined against cabbage aphid by their spraying on cabbage plants highly infested with aphid while their effect against cotton leafworm were determined by collecting leaves samples directly and after different periods of spraying and transferred to laboratory where they were introduced to 4^th instar larvae of cotton leafworm. Results obtained indicated that actellic at full (385 cm³ / 100L) recommended rate showed the highest effect aga•nst both two studied insects followed by the mixture of mineral oil CAPL-2 at 0.75% + actellic at 1/10 (38.5cr•j /100L) recommended rate and CAPL-2 at 1..F.%. Therefore the mixture is preferred than oil alone or pesticide alone for reducing their quantity, costs and less polluted to the environment.
