This study examined the species compositions of the parasitoid complex associated with eight sorts of cynipid galls on three coexisting Fagaceae species and the life-history traits of the dominant parasitoid and inquiline species. Fourteen parasitoid species of the superfamily Chalcidoidea and one inquiline cynipid species of the genus Synergus emerged from the galls collected. Seven parasitoid species and Synergus sp. were recorded from two or more sorts of galls. Twelve parasitoid species were classified into five primary parasitoids and seven facultative hyperparasitoids according to the host types of parasitoid. The primary parasitoids, Megastigmus nipponicus and Cynipencyrtus flavus, had clear peaks of adult emergence from galls, suggesting the synchrony of their seasonal occurrences with those of growth stages of their hosts. The facultative hyperparasitoids, Eurytoma brunniventris and Eupelmus urozonus, consecutively emerged from various sorts of galls, suggesting no synchrony with any particular host. Thus, the differences in life-history traits between the primary parasitoids and the facultative hyperparasitoids might be due to the differences of their ranges of host species. The emergence of the inquiline, Synergus sp., differed from those of the primary parasitoids in generally emerging from the gall of each cynipid species during one particular period, suggesting that the species synchronizes its emergence and oviposition periods with the growth and differentiation stage of galls limited in time.
