在埃及 ,黄盾食蚧蚜小蜂Coccophagusscutellaris(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CeroplastesfloridensisComstock ,CoccushesperidumL .,Pulvinariafloccifera(Westwood) ,P .psidiiMaskell,Saissetiacoffeae(Walker)以及S .oleae(Oliver)来饲养黄盾食蚧蚜小蜂。 1 999- 2 0 0 0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— 1 1月间。C .scutellaris对S .coffeae和S .oleae的最高寄生率分别是发生在 1 999年 1 1月和 8月的 2 6%和 2 2 % ,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
In Egypt, Coccophagusscutellaris (Dalman) is a parasitic wasp that is effective against scale insects. In the study, six insects, Ceroplastes floridensisComstock, Coccushesperidum L., Pulvinaria floccifera (Westwood), P. psidiiMaskell, Saissetiacoffeae (Walker) and S.oleae (Oliver) From 1985 to 2000, C. Sccutellaris occurred on a large scale from January to January in five places, Beni Suef, Cai ro, Giza, Gharbiya and the northern coast of Egypt. The highest parasitism rates of C. sclutella to S. coffeae and S.oleae were 26% and 22% of those in January and August 1999, respectively. Therefore, it can be concluded that the These two scale insects are effective parasitic wasps
