<br/><br/> several problems in controling pests as well as pollution is have been risen from the intensive use of insec:licic!es. Therefore, this work was Carried out at Sakha Agricuttral Research station during 2007 and 2008 cotton growing seasons to evaluate the initial and residual ellect of some chitin-synthesis inhibijors (diafenthiuron and buprotezin), and the dinilromelhelin derivative Amidor (imidacloprid) and the mineral oil (KZ-<oil) against the cotton aphid, Aphis gossypii. In addition it was planned to evaluate the Initial and residual effect of Anjio (thiamethoxam + lambdacyhalolhrin), Amidor (imidacloprid) and KZ-oil, on the whitefly Bemisia labaci (adult and immature stages) and their associated natural enemies. Results showed that imidacloprid induced the highest initial and residual reduction giving (95.8 - 98.8%) in the first season and (96.8 - 98.9%) in the second season against the cotton aphid, while buprofezin (Applaud) came in the second order recording (80.5 - 90.3%) in the first season, and (80.3 - 88.7%) in the second season. While, the initial and residual activity of diafenlhiuron (Polo) was (68.5 - 90.9% reduction) in the first season and (66.02 - 84.9%) in the second season.
