The study was conduct to survey.the scale insect and mealybug species and their associated natural enemies as well as the degree of infestation on avocado trees. The obtained results revealed eight species of scale insects and Mealybugs. Two coccid species. [Coccus hesperidum L. and Pulvinaria psidii (Mask.)], Four diaspidid species [Hemiber/esia lataniae (Sign.), Aulacaspis tubercularis (Newst)., Aonidiella aurantii (Mask.) and Aspidiotus nerii Bouche] and Two Pseudococcid species [Pseudococcus /ongispinus (Targ.-Tozz.f and Ferrisia virgata (Ckll.)]. Associated parasitoids were Coccophagus scutellaris on C hesperidum, Aphytis lepidosaphes, Habrolepis aspidioti and Marietta leopardina on H. lataniae, Encarsia cttrina and Habrqlepis diaspidi on A. tubercularis and Anagyrus spp. on P. longispinus. Also, associated predators were Roda/ta cardinalis on C hesperidum and two coccinellid predators ( Cryptolaemus montrouzieri and Scymnus synacus) on P. /ongispinus. H. latamae was the most abundant (56.8%) followed by F. virgata (42.5%) , A. tubercu/aris (39.8%) , P. longispinus (31.7 % ), C hesperidum (26.6%), P.psidii(15%), A. aurantii (15%) and A. nerii(14.3%). Hass cultivar proved the highest infestation rate in the four localities followed by Boothy and Waldim cultivars. Fuerte, Gwen and Lula cultivars had the lowest infestation rate.  aSummary in Arabic. 0aAvocadoxDiseases and pests. 0aMealybugsxHost plants 0aMealybugsxParasites.1 aSerag, A.
