Field experiments evaluation were carried out in a private orchard cultivated with olive trees of (Manzanillo cultivar) at Wady El-Natroon region, throughout two subsequent seasons of2016 and 2017 to control both of the lepidopteran olive moths; Prays oleae and the jasmine moth, Margaronia unionlis. Five treatments was applied; the release of the parasitoid-Trichogramma evanescens alone or followed with certain insecticides. The results showed that the subsequent monthly use treatment of release the parasitoid-T. evanescens then Nimbecidine® 0.03% E.C against P. oleae gave the best efficient treatment recording higher infestation reductions of 83.41 and 82.12% in both seasons of 2016 and 2017, respectively, followed by the more or less efficiency bimonthly release of the T. evanescens then Nimbecidine® 0.03% E.C, Nimbecidine® 0.03% E.C, Deltachem Super® 2.6% E.C, and release of T. evanescens only, that gave 60.11 & 67.88%, 57.85 & 64.63%, 55.16 & 56.91% and 52.48 & 53.66%, respectively. As for the M. unionlis the results indicated that the subsequent monthly use treatment of release the T. evanescens then Nimbecidine® 0.03% E.C gave the best efficient control recording higher infestation reductions of 86.89 & 80.39% in both seasons 2016-2017, respectively, followed by the performed treatment of Nimbecidine® 0.03% E.C, the bimonthly release of T. evanescens then Nimbecidine® 0.03% E.C, Deltachem Super® 2.6% E.C, and release of T. evanescensonly, that gave infestation reductions amounted to 77.75 & 68.81%, 70.73 & 64.31%, 70.43 & 63.99 and 60.37 & 52.09%, respectively. Therefore, the monthly hang of the cards of parasitoid-T. evanescens followed by Nimbecidine® 0.03% E.C application at the following month could be recommended as effective of control both the insect-pests.
