Field experiments were carried out during 2007 and 2008 fall seasons to evaluate the efficiency of some natural control agents against some insect pests infesting cucumber plants at Alexandria University Experimental Station. The side effects of these control agents against the predatory insect, Syrphus corollae F. were also investigated. In both seasons Confidor, Achook and Runner were the most effective in reducing aphid (Aphis gossypii Glov) and whitefly(Bemisia tabaci (Genn.)) numbers Chema oil, Botany guard and Breef recorded the least reduction percentages. Runner revealed the highest leaf miners control in both seasons. On the other hand, in both seasons, Confidor proved to be the most toxic against S, corollae followed by Runner, Achook and Chema oil. Botany guard and Breef had the least side effects against S. corollae in both seasons.
