Faunistical analyse On the basis of the helminthological examination of about 600 voles, collected in the last ten years in Hungary, the cestode fauna of the Microtinae species of the country became known. Concerning data are summarized in Tables 2 and 3« Clethrionomys glareolus was found to be infested with tapeworms in the highest percentage (32*2%), and the greatest number of cestode species (13) was found also in the bank vole. The common vole (Microtus arvalis)was infested with tapeworms in 24.3% (10 cestode species). The pine vole (Pitymys subterraneus) was infested with 5 species in 43"2%. The structure of the tapeworm alliance in M. arvalis, C. glareolus and P.subterraneus in Hungary is demonstrated in Pig. 18. The few Microtus agrestis examined were strongly infested with 5 tapeworm species, Ondatra zibethica with 2 species. Seven of the tapeworm species parasitizing voles were usually not found in other rodents. These species seem to have been adapted closely to the species of the subfamily Microtinae. These are: Catenotaenia cricetorum Kirshenblat ,1949, Andrya sp.

, Paranoplocephala brevis Kirshenblat, 1938, Aprostatandrya macrocephala (Douthitt

,1915), Hymenolepis horrida (Linstow, 1901), H. asymmetrica Janicki, 1904, and the larval form of Taenia crassiceps (Zeder, 180Ö). Skrjabinotaenia lobata (Baer, 1925) was found in one case in M.agrestis and in two cases in C. glareolus. The voles in these localities were living in close association with Apodemus populations which are known to be the typical hosts of S. lobata. The tapeworm fauna of voles in Hungary corresponds to that known from other parts of Europe. The tapeworm species recorded from the neighbouring countries(see TENORA, MURAI and MÉSZÁROS, 1973) were nearly all found also in Hungary with the exception of Hymenolepis diminuta Rud., 1819, H. fraterna Stiles, 1901, and H. straminea (Goeze, 1782, syn.: H. microstoma Dujardin, 1845). Therefore, on the basis of the investigation of 3000 ro136
