Abstract

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.

초록

본 연구는 감귤의 해충인 귤굴나방(Phyllocnistis citrella Stainton) 의 포식 기생자 천적의 종류와 기생률을 조사하기 위하여 수행하였다. 2013~2014 제주 감귤원에서 발견된 귤굴나방 포식 기생자 천적은 좀벌상과에 속한 총 7종을 발견되었다. 그 중 좀벌과에 속한 Sympiesis striatipes가 73%, Quadrastichus sp.가 22%로 우점하였다. 나머지 종은 Neochrysocharis sp., Ageniaspis sp., Pnigalio sp., Holcopelte sp., Trichomalopsis sp. (Pteromalidae) 등이었다. 천적의 평균 기생률은 관행방제 과원에서 10.7%, 무농약 과원에서는 32.2% 이었다.
