Several problems in controlling pests as well as pollution have been risen from the intensive use of insecticides. Therefore, this work was carried out at Shiba village, Zagazig district during summer plantation of 2010 season to evaluate the initial and residual effects of five insecticides against tomato white fly, Bemisia tabaci (Genn.), cotton aphid, Aphis gossypii (Glov.) and onion thrips, Thrips tabaci (Lind.) infesting squash plants and their associated natural enemies, Chrysoperla carnea Steph., Orius sp., Scyminus sp., Coccinella sp., Paederus alfierii Koch, Syrphus corollae F., Aphidoletus sp. and mummies. The obtained results could be summarized as follows: MTI-446 had the highest effect against B. tabaci after the 1st spray ) and sumicidin after the 2nd spray by using ULV sprayer while chemisol was the least effective by using taral motor sprayer after the 2nd spray, but the same last tool with mospilan showed high % reduction at the 1st spray. MTI-446 after the 1st spray and jojoba after the 2nd spray by using UL V sprayer exhibited a high efficacy against A. gossypii. Also, jojoba at the 1st and sumicidin at the 2nd spray by using UL V sprayer against T. tabaci had a high efficacy. All the tested insecticides exhibited a moderate hazardous effect on Scyminus sp., Orius sp. and Syrphus corollae after the 1st & 2nd sprays and a high hazardous effect on Paederus alfierii, while mospilan, MTI-446. and jojoba proved to be the most safe compounds for predators and parasites.
