Gall communities of the bedeguar gall wasp, Diplolepis rosae, have been explored by many authors during the years because of their species richness and relevance for biological and ecological studies. Some observations focused on the D. rosae larvae revealed the critical importance of hibernation for successful development of adult individuals. However, there are no data on the effects of winter diapause of the gall inducer on other gall inhabitants, like parasitoids and inquilines. In the present study, the parasitoid community composition, species abundance and species diversity in the absence of hibernation of the gall-inducer from samples collected from Stara Planina Mts and the Rhodope Mts, Bulgaria, were investigated. The data from non-cold stored samples were compared with those of a similar study from Vitosha Mts, where there was successful hibernation of the gall-maker. In addition to D. rosae and its inquiline Periclistus brandtii, a total of 18 hymenopteran parasitoid species emerged from the bedeguar galls; they belonged to Eulophidae (three species), Eupelmidae (five species), Eurytomidae (three species), Pteromalidae (two species), Torymidae (three species) and Ichneumonidae (two species). The estimated diversity indices showed moderate parasitoid species diversity at the studied areas. The most numerous species in the samples were Glyphomerus stigma and Pteromalus bedeguaris. Two species are new to the Bulgarian fauna - Eurytoma caninae and Eupelmus fulvipes. Additionally, one association with the rose bedeguar galls is newly discovered - Oomyzus galerucivorus has not been previously recorded as member of this community One unknown species belonging to genus Stepanovia was also found.
