Results showed that all three insecticides effected parasitic efficiency, of <em>Aphidiusmatricariae</em>and Nimex recorded highest mortality rate on <em>Myzuspersicae</em> (Sulzer) which was 98-73. All three used pesticides (Actara, Match and Nimex) affected predatory and parasitic efficiency after direct exposure, while less effects the same pesticides on predator efficiency of both <em>C.septempunctata</em> and <em>C. novemnotata</em> have been recorded after indirect treatment.
