| Abstract |
The present work of Parlatoria blanchardi (Targioni-Toz.zetti) (Homoptera: Diaspididae), deals with its host plants, distribution, population dynamics and its natural enemies. During 2004 - 2005, the date palm scale, P. blanchardi, was recorded attacking 4 host plants in 9 localities of 8 governorates in Egypt and it was attacked by 3 parasitoids and 3 predators. These parasitoids are Aphytis phoenlcis De Bach & Rosen, Encarsia citrina (Craw) and Pteroptrix aegyptica Evans & Abd-Rabou. The predators are Chilocorus bipustulatus L.., Chrysoperla carnea Steph., Chrysopa vulgaris, Rodalia cardinalis Muls, and Scymnus syriacus Muls. The seasonal abundance of P. blanchardi and its natural enemies were studied for two successive years, from Jan. 2004 to Dec. 2005, on date palm trees at Giza and North Sinai Governorates. The obtained data showed that, the insect population (pre-adult and adult) per 50 leaflets of date palm trees had two peaks during April 15th. (7032 insects) and Dec. 15th. (2972 insects) in the first year. In the second year the insect also had two peaks during April 15th. (7331 insects) and Dec. 15th. (3444 insects).These results indicated that E.citrina and C. bipustulatus are the active natural enemies attacking P. blanchardi in Egypt
