Sweet pepper is an important vegetable crop in Egypt. It is cultivated for local consumption and exportation. The crop is attacked by a large number of pest species such as Western flower thrips, Frankliniella occidentalis (Pergande), whitefly, Bemisia tabaci (Genn.), the two-spotted spider mite, Tetranychu surticae Koch, and the beet armyworm, Spodoptera exigua (Hubner). The present study was conducted on the sweet pepper cultivated in greenhouses, during the winter plantation 2016/17 in a commercial farm located at Berkash district, Giza Governorate, Egypt. Three control programs were practiced: the first used biological control agents (BC), the predators, Orius albidipennis (Reuter), Macrolophus caliginosus (Wagner), Chrysoperla carnea (Steph.), and the egg parasitoid, Trichogramma euproctidis (Girault); the second was sprayed by the recommended chemical control program of the farm (CC); and the third was untreated as a control. Obtained results revealed that the BC program was the most significant one for controlling the complex of sweet pepper pests. Also, applying the BC program resulted to a high yield of sweet pepper production (35.06% increasing than the control).

温室甜椒害虫生化防治方案的比较研究

甜椒是埃及重要的蔬菜作物。它是为本地消费和出口而种植的。该作物受到大量害虫的袭击，例如西方花蓟马，西洋蓟花（Pergande），粉虱，烟粉虱（Bemisia tabaci（Genn。），两斑蜘蛛螨，Tetranychu surticae Koch和甜菜夜蛾，Spodoptera exigua）。 （哈伯纳）。本研究是对位于埃及吉萨省Berkash区一个商业农场的2016/17冬季种植园中温室大棚种植的甜椒进行的。实践了三个控制程序：第一个使用生物控制剂（BC），捕食者，奥里斯albidipennis（路透社），Macropophus caliginosus（瓦格纳），Chrysoperla carnea（Steph。）和卵类寄生虫，Trichogramma euproctidis（Girault）；第二种是按照农场（CC）推荐的化学控制程序喷洒的；第三个未作为对照。获得的结果表明，BC程序是控制甜椒害虫复合物的最重要的程序。同样，应用BC程序导致甜椒产量高（比对照增加35.06％）。
