Survey of the Scale Insects and Mealybugs Species and its Associated Natural Enemies on Mango Trees in Different Governorates in Egypt

Abstract

Studies on survey of scale insects and mealybugs infested mango trees and its associated parasitoids and predators were carried out at five governorates in Egypt during two successive years (2013- 2014 and 2014- 2015). The obtained results provided the occurrence of ten scale insects and mealybugs species found on mango trees. These species were Kilifia acuminata (Signoret), Ceroplastes floridensis Comstock, Aulacaspis tubercularis Newstead, Pulvinaria psidii (Maskell), Aonidiella aurantii (Maskell), Lepidosaphes pallidula (Maskell), Planococcus citri Risso, Icerya seychellarum (Westwood), Maconellicoccus hirsutus (Green) and Hemiberlesia lataniae (Signoret). Also, We recorded many species of parasitoids were associated with scale insects and mealybugs during two years of study. The parasitoids species were Metaphycus flavus (Haward), Habrolepis aspidioti( Compere & Annecke), Encarsia citrine Craw, Aphytis chrysomphali Mercet and Aphytis lepidosaphes Compere and we recorded several of predators were associated with scale insects and mealybugs, Rodalia cardinalis (Mulsant), Scymnus syriacus (Marseul), Exochomus flavipes (Thunberg) and Hemisarcoptes coccophagus (Meyer).
