摘　　要：通过调查采集和鉴定 ,初步获得了广东省内烟粉虱蚜小蜂 6种 ,其中隶属于恩蚜小蜂属EncarsiaFoerster的有 4种 ,隶属于桨角蚜小蜂属ErtmocerusHaldeman有 2种。调查发现 ,蚜小蜂在蔬菜和园林植物上的寄生动态有一定的规律 ,4月中旬至 6月下旬和 9月下旬至 1 1月下旬寄生率较高 ,6月下旬至 8月上旬和 1 1月下旬至翌年 2月下旬寄生率较低。初步确定双斑恩蚜小蜂Encarsiabimaculata和桨角蚜小蜂Eretmocerussp .为广东省内烟粉虱的寄生蜂优势种类。Six species of aphelinid parasitoids of Bemisia tabaci were identified in Guangdong Province, including 4 species of Encarsia Foerster and 2 species of Eretmocerus Haldeman. The parasitic rate of aphelinid parasitoids on B.tabaci on some important vegetables and ornamental plants were higher during two periods: April to June, September to November. While in the period of a year, the parasitic rate were lower. According to the result of investigation, Encarsia bimaculata and Eretmocerus sp. were two dominant species in Guangdong.
