Parasitoid community and parasitism in galls of the three Western Palaearctic oligo- and unilocular Diplolepis species (Hymenoptera: Cynipidae)

Abstract

Three Western Palaearctic Diplolepis Geoffroy, 1762 species are known to cause oligoand unilocular galls on wild roses: Diplolepis spinosissimae (Giraud, 1859), D. eglanteriae (Hartig, 1840) and D. nervosa (Curtis, 1838). Several studies have focused on the species composition of parasitoid communities developing inside these galls; however their parasitism rates are still unknown. We analysed galls collected in the eastern Carpathian Basin (Hungary and Romania). Here we report for the first time parasitism rates from these species’ galls. With 6 figures.
