| Abstract: | 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. |
