Field experiments were conducted in winter and summer seasons to study the efficiency of insect growth regulator (Altosid XR briquettes), monomolecular surface film (Aquatain) and synthetic pyrethroid insecticide (lambdacyhalothrin) and the extent of their impact in control programs. The efficacy of Altosid XR briquettes and Aquatain against culicine larvae and pupae was evaluated in selected pools under field conditions in Atreeb area, Qalyubiya Governorate. Altosid XR briquettes had long-lasting effect on mosquito population during winter than summer seasons. Monomolecular surface film, Aquatain had high effect on mosquito population at a dose of 2 ml/m2 than 1 ml/m2. The effect of treated-curtains with 10 ml/m2 lambdacyhalothrin insecticide on inhibit mosquito adults' entry was determined by using treated cotton and polyester curtains. Cotton-treated curtains were suitable than polyester treated curtains.
