520 _aSeveral problems in controlling pests as well as pollution have been risen from the intensive use of insecticides. Therefore, this work( was carried out at Sakha Agricultural Research Station during 2001 cotton growing season to evaluate the initial and residual effect of two chitin synthesis inhibitors (diafenthiuron and buprofezin), one conventional insedicides (Triazophos), two dinitromethelin derivative (Confidor and Best) and one insect growth regulator (Thiamethoxam) against cotton whitefly Bemisia tabaci (adult and immature stage) and their associated natural enemies summarized results showed the following: Confidor and Best induced the highest initial reduction giving 84.2 and 82.7% respectively against immature stage of the whitefly, the rest of tested compound were ranged from (75.4 to 77.3 % redudion). Where Buprofezin and Confidor induced the highest residual activity on immature stage of whitefly, (73.77 and 72.9% reduction). For the effect on the mature stages Confidor and Best induced the highest initial and residual activity giving 81.8 and 80.6% and 71.5 and 67.5%, respectively. The other tested compounds caused initial activity ranged between• (64.7 to 75.5% reduction), while they caused residual activity ranged between (47.6 to 61.8% reduction).
