Abstract

The parasitoid complex associated with Phyllonorycter coryli and P. nicellii (Lepidoptera: Gracillariidae) leaf miners on hazel in Poland was examined and the contribution in the parasitoid community as well as the parasitization level of two species was defined. The parasitoid community of the nut leaf blister moth, Phyllonorycter coryli (Nic.), and the red hazel midget, Phyllonorycter nicellii (Stt.), was studied in three localities situated in Lublin. At each locality, leaves with visible mines were collected from the shrubs Corylus avellana L. and C. maxima Mill. cv. 'Purpurea'. Of the 518 larvae and pupae of Ph. coryli, 47 individual of parasitoids were obtained. However, 152 individuals of parasitoids from 898 mines of Ph. nicellii successfully emerged. The highest contribution in the parasitoid complex of both leaf miner species was found for the chalcidoid family Eulophidae. The parasitoid community of Ph. coryli was made up of 11 species, 7 of which had not been recorded from this host before. Thirteen parasitoid species were reared from larvae and pupae of Ph. nicellii, 8 of which were recorded for the first time. The species from the genus Chrysocharis had the greatest contribution in the parasitoid community of Ph. nicellii, while Pediobius saulius Walk. was dominant in the parasitoid fauna of Ph. coryli.
