Pelov, V. (Plant Protection Institute, Kostinbrod (Bulgaria))
The parasitoid species were isolated from Semudobia betulae (Psilonotus achaeus Walk., Aprostocetus escherichi Szel., A. constrictus Grah., Pnigalio argaules Walk., Minotetrastichus ecus Walk., Entedon heyeri Ratz. - Eulophidae; Eupelmus urozonus Dalm. - Eupelmidae; Lioterphus fuscicornis Walk. - Torymidae; Metaclisis sp. - Platygasteridae; Elasmus sp. - Elasmidae). The relation of the last species with S. betulae is not clear. Predominant in number parasitoids are Ps. achaeus Walk, A. constrictus Grah. and A. escherichi Szel. The species Psilonotus achaeus Walk, A. constrictus Grah, A. escherichi Szel., Entedon heyeri Ratz., L. fuscicornis Walk. and Metaclisis sp. are new to the fauna of Bulgaria. Total parasitism was 89% and 62% in 1991 and 1992 respectively.
