| 摘 要： | 在埃及，黄盾食蚧蚜小蜂Coccophagus suteelaris(Dalman)是一种有效防治蚧壳虫的寄生蜂，研究中分别用6种蚧壳虫Ceroplastes floridensis Comstock,Coccus hesperidumL.,Pulvinaria floccifera (Westwood),P.psidii Maskell,Saissetia coffeae(Walker)以及S.oleae(Oliver)来饲养黄盾食蚧蚜小蜂，1999－2000年间，在埃及的Beni-Suef,Cairo,Giza,Gharbiya和北海岸等5个地方，C.scutellaris大规模的发生在7－11月间，C.scuteelaris对S.coffeae和S.oleae的最高寄生率分别是发生在1999年11月和8月的26％和22％，因此可以认为，黄盾食蚧蚜小蜂是对两种蚧壳虫有效的寄生蜂。

| Abstract: | Coccophagus scutellaris (Dalman) is one of the specific parasitoids that attack soft scale insects in Egypt. In the present study, C. scutellaris was reared from 6 species of soft scale insects. These are Ceroplastes floridensis Comstock, Coccus hesperidum L., Pulvinaria floccifera (Westwood), P. psidii Maskell, Saissetia coffeae (Walker) and S. oleae (Oliver).The abundance of C. scutellaris was monitored from July to Nov. 1999-2000 in five localities in Egypt, the Beni Suef, Cairo, Giza, Gharbiya and the Northern coast. C. scutellaris is considered an effective parasitoid of S. coffeae and S. oleae with maximum parasitism rates reaching 26% and 22% in Nov. and Aug. 1999, respectively. |
