Abstract

The Coccophaginae parasitoids ( Hymenoptera' Aphelinidae) can play a
distinguished role in control of armored scale insects (Hemoptera Diaspididae) in
Egypt, The present work deals with the survey of subfamily Coccophaginae and its
role in controlling the armored scale insect in Egypt. Abundance of these parasitoids
was carried out on 6 host plants attacking by 8 armored scale insects in 7
governorates . The resuits indicated that ten species of subfamily Coccophaginae
attacking armored scale insects in Egypt. Thses are Encarsia aurantii‘ {l—oward),
Encarsra ber/esei (Howard), nears/a Citrina Craw, Encarsi‘a tourism/yr Beriese &
Paoli, Pteroptri'x aegypti‘ca Evans & Abd-Rabou ,Coccobl’us sp.,. Coccophagoids
kumanai’ (Silvestri),. Coccophagords si'mr/i'es (Masi), Encarsr'a perni‘cios/ (Tower),
Pteroptn’x bi'co/or (Howard). The maxi‘num parasitism rates of the first five species
ranged from 17 — 35% The rest ofthe species, the parasitism rates was rarely,
