Abstract: Field experiments were carried to evaluate five programs with three sprays of application using nine insecticides belongs to five different chemical groups on reducing the infestation of cotton bollworms, pink bollworm Pectinophora gossypiella (Saund.) and spiny bollworm Earias insulana (Boisd.) and some other sucking pests, cotton whitefly, Bemisia tabaci (Genn.), cotton aphids, Aphis gossypii (Colov.), cotton jassid Empoasca lypica (de Berg), cotton thrips Thrips tabaci (L.) and spider mite Tetranychus urticae (Koch) in Dakahlia Governorate during 2005 cotton season. According to general of reduction average it is clear that both the program 1 (1st Spray Beta-cyfluthrin, 2nd Spray Malathion and 3rd Spray Spinosad) and the program 4 (1st Spray Lufenuron, 2nd Spray Malathion and 3rd Spray Spinosad) induced the highest effect representing 81.04 and 81.08% reduction in pink bollworm larval population, respectively. The percentages of infestation of the spiny bollworm recorded during the season in each of experimental plots at three tested sprays were too low. Also, the results obtained revealed that all programs were significantly reduced the population density of the sucking pests at any date of inspection during all application.
