| Abstract: | In field studies in Hunan, China, the rate of parasitism by Coccygomimus nipponicus [Pimpla nipponicus], Vulgichneumon diminutus, Phaeogenes sp. and Itoplectis naranyae on Susumia exigua [Marasmia exigua], Eriborus terebrans [Diadegma terebrans] on Tryporyza incertulas [Scirpophaga incertulas], I. naranyae on the pyralid Chilo suppressalis, Anagrus spp. and Ootetrastichus sp. [Aprostocetus sp.] on rice planthoppers [Delphacidae] and Tomosvaryella oryzaetora on Nephotettix cincticeps was found to be about 15% in the overwintering stage of the hosts. |
