| Abstract |
During the present work, fern scale, Pinnaspis aspidistrae (Signoret) (Homoptera:Diaspididae), is recorded, for the first time, as a serious pest on mango trees in Egypt. This work includes distribution, parasitoids as well as the seasonal abundance of this scale insect. During 2002 - 2004 the scale insect, P. aspidistrae, was recorded in 9 localities of 5 governorates in Egypt and it was attacked by parasitoids: Aphytis matruhi Abd-Rabou, Aphytis mytiaspidis (Le Baron), Encarsia citrina (Craw), Marietta leopardina Motschulsky and Habro%pis aspidioti Compere & Annecke. The seasonal abundance of P. aspidistrae and its parasitoids were studied for two successive years from March 2002 to February 2004 on mango trees in Beheira and Qalyubiya Governorates. The obtained results showed that the insect population (pre-adult , adult female and gravid female) per 100 inch leaves of mango trees has three peaks during May lst. (3460 insects), July 1st. (4694 insects) and January 1st. (1310 insects) in the first year. In the second year it has two peaks during July 1st. (4394 insects) and February 15th. (1575 insects). The results indicated that A. mytilaspidis and E. citrina are the effective parasitoids attacking P. aspidistrae in Egypt.
