This study was conducted to investigate the species of native parasitoids attacking Phyllocnistis citrella and their parasitism in citrus orchards in Jeju, Korea. During the survey period from 2013 to 2014, seven parasitoids belonging to Chalcidoidea were found: majority of the parasitoids were Sympiesis striatipes with 73% and Quadrastichus sp. with 22% in Eulophidae. The others were Neochrysocharis sp., Pnigalio sp., Holcopelte sp., Ageniaspis sp. (Encyrtidae) and Trichomalopsis sp. (Pteromalidae). Average parasitism rate reached 10.7% in orchards with spraying insecticide, and 32.2% in environmental-friendly managed orchards.
