| Abstract | ||
| The latania scale, Hemiberlesia lataniae (Signoret) (Hemiptera: Diaspididae) is a dangerous pest in different locations in Egypt. During the present work, 17 species of natural enemies were collected from samples of H. latania. These are: Aphytis aonidiae (Mercet), Aphytis chilensis Howard, Aphytis lingnanensis Comepre, Aphytis mytilaspidis (Le Baron) (Hymenoptera: Aphelinidae), Chilocorus bipustulatus L. (Coleoptera: Coccinellidae), Chrysoperlla carnae Steph. (Neuroptera: Chrysopidae), Coccinella undecimpunctata L (Coleoptera: Coccinellidae), Encarsia aurantii (Howard), Encarsia lounsburyi (Berlese and Paoli) (Hymenoptera: Aphelinidae), Exochomus flavipes Thunb. (Coleoptera: Coccinellidae)and Habrolepis aspidioti Compere and Annecke (Hymenoptera: Encyrtidae), Marietta leopardina Motschulsky (Hymenoptera: Aphelinidae), Orius laevigatus Fieb. (Hemiptera: Anthocoridae), Pharoscymnus various Kirsch., Rodalia cardinals Muls (Coleoptera: Coccinellidae), Scymnus syriacus Mars. (Coleoptera: Coccinellidae) and Syrphus corollae Fabricius (Diptera: Syrphidae). Abundance of the latania scale, H. lataniae natural enemies were evaluated in different locations in Egypt, representing various bioclimatic regions during two successive years 2009-2010. The results indicated that the parasitoid, H.aspidioti the most abundant species associated with H. lataniae infested mango trees in Giza. The maximum rate of parasitism reached 9.1 and 7.3% in October, 2009 and 2010, respectively. The percentage of parasitism ranged from 0.1 to 9.1% in the first year and from 0.3 to 7.3% in the second year. The predator C. carnae was the most abundant species and occurred all over the years under investigation on H. lataniae on olive trees inAlexandria and the maximum number was 25 individuals /60 leaves and 15 twigs in July in the first year and 17 individuals/60 leaves and 15 twigs in June in the second year. Keys for parasitoids and predatorsassociated with the latania scale, H. lataniae are included. | ||
