Abstract
Twenty nine natural enemies were associated to this pest (11 parasitoids and 18 predators). Population dynamics of recorded five hymenopterus parasitoids [i.e. Metaphycus bartletti Annecke & Mynhardt, M. ilavus (Howard), Microterys (lavas (Howard), Di­versinervus elegans (Silvestri) and Scutellista cyaneae (Mots.)) were studied in a Northern Coast site during 1998-1999 and 1999­2000. M. bartletti was the most effective parasitoid of Saissetia Wen on olive trees with maximum rates of parasitism of 23.0 and 24.5% during 1998-1999 and 1999-2000, respectively. The population dynamics of 6 predators were studied at the same site. Two peaks were recorded annually for Chilocorus bi­pustulatus L., Chrysoperla carneae (Stephens), Coccinella un­decimpunctate (L.), Orius sp., and Scymnus syriacus Mars. Ex­ochomus flavipes Thrum and Orius sp., were recorded at low populations throughout the two considered years, respectively.
