Abstract
Several problems in controlling pests as well as pollution is have been risen from the intensive use of insecticides. Therefore, this work was Carried out at Sakha Agricultral Research Station during 2007 and 2008 cotton growing seasons to evaluate the initial and residual effect of some chitin-synthesis inhibitors (diafenthiuron and buprofezin), and the dinitromethelin 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 + lambdacyhalothrin), Amidor (imidacloprid) and KZ-oil, on the whitefly Bemisia tabaci (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 diafenthiuron (Polo) was (68.5 – 90.9% reduction ) in the first season and (66.02 – 84.9%) in the second season. KZ – oil induced a moderate initial and residual effect, where it exhibited (63.7 – 64.6%) and (65.1 – 65.3%) reduction in the two seasons respectively . As for the effect of thiamethoxam+ lambdacyhalothrin, imidacloprid and KZ – oil against the white fly B. tabaci mature stage , thiamethoxam+ lambdacyhalothrin induced the highest initial reduction giving 73.3 and 76.3% in the two seasons respectively, followed by Amidor (72.7 and 69.9%, respectively) and KZ – oil (68.5 and 69.1% respectively). While, thiamethoxam+ lambdacyhalothrin induced the highest residual activity (80.03 and 78.1% reduction) in the two seasons respectively, followed by KZ – oil (72.2 and 74.9% reduction) and thiamethoxam+ lambdacyhalothrin (70.8 and 70.9% reduction) in the two seasons , respectively. Regarding the effect on immature stage thiamethoxam+ lambdacyhalothrin induced the highest initial effect in the two seasons (76.2 and 86.3% reduction) respectively, followed by imidacloprid and KZ – oil which gave (71.9 and 59.9% reduction) and (72.2 – 64.8% reduction) in the first and second seasons. On the other hand imidacloprid induced the highest residual effect in the two seasons giving 77.06% and 75.7%, respectively, followed by KZ – oil recorded 74.7 and 75.6% , respectively, and thiamethoxam+ lambdacyhalothrin gave 74.4 and 74.3% , respectively. As for the side effect on the associated natural enemies, (chrysopa sp., paederus alfierii, orius spp., scymnus spp. and true spider), thiamethoxam+ lambdacyhalothrin was the most effective one on the population density of predators followed by diafenthiuron, buprofzin and KZ – oil while imidacloprid had the weakest effect. Thus, imidacloprid can be used in the integrated pest management programs to control both aphids, and different stages of whitefly, especially it was safe to the natural enemies.
