Sixteen localities in Korea were studied to determine the distribution and parasitism of parasitoids emerged from fly pupae in accumulations of domestic animal manure during 1997 and 1998. Thirteen parasitoids species emerged from sampled pupae were Spalangia endius Walker, S. nigra Latreille, S. nigroaenea Curtis, S. sp., Muscidifurax raptor Girault & Sanders, Pachycrepoideus vindemiae (Rondani), Nasonia vitripennis (Walker), Dirhinus herperidum (Rossius), Trichopria sp. and 4 unidentified species. Mean relative abundance of each species was 70% for S. nigroaenea, Muscidifurax raptor 19.13%, S. endius 7.53%, P. vindemiae 1.94%, D. hesperidum 0.59%, S. nigra 0.47%, and other species were rare. Relative abundance of predominance species to localities were above 90% for S. nigroaen-ea at Youngdong-gun, Youngju city, Hongchon-gun, Pusan city, Yanggu-gun and Haman-gun, 80% to 90% at Yoju-gun, Paju-gun, Chungju city and Cheju, 60% to 80% at Youngchon city, Cheongup city and Jangsung-gun, 49.3% and 44.3% for M. raptor at Seosan city and Kongju city, and 64.4% for S. endius at Kimhae city.
