在埃及,黄盾食蚧蚜小蜂Coccophagus scutellaris(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 flridensis Comstock,Coccus hesperidum L.,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,Cai-ro,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.scutellaris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这两种蚧壳虫有效的寄生蜂.%Coccophagus scutellaris (Dalman) is one of the specific parasitoids that attack soft scale insects inEgypt. In the present study, C. scutellaris was reared from 6 species of soft scale insects. These are Ceroplastesflori-densis 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 fivelocalities in Egypt, the Beni-Suef, Cairo, Giza, Gharbiya and the Northern coast. C. scutellaris is considered an ef-fective parasitoid of S. coffeae and S. oleae with maximum parasitism rates reaching 26% and 22% in Nov. and Aug.1999, respectively.
