Vig Károly: Zoological Research in Western Hungary. A history (Szombathely, 2003)
Phylum Nematoda 63 ous terrestrial and limnic habitats in the Hanság district, especially in the FertőHanság National Park, and 143 nematode species were recorded there —20 per cent of the free-living nematode fauna in Hungary. This confirms that that the nematode fauna of the Hanság is very rich. The 143 species found belong to 79 genera and 41 families. Five species — Eumonhystera pannonica, Mesodorylaimus flagellifer, M. hrevicylindrus, Aporcelaimellus médius and A. alius —proved to be new to science, and 19—Ceratoplectus gracilis (Torquentia), Pellioditis pellio, Malenchus cognatus, Nagelus leptus (Secernentia), Alaimus acutus, Tobrilus consimilis, T. longicaudatus, Prionchulus punctatus, Dorylaimus macroproctus, Mesodorylaimus parabastiani, Aporcelaimellus amylovorus, A. pycnus, A. samarcandicus, Makatinus aquaticus, Ecumenicus parvus, Labronemella czernowitziensis, Labronema vulvapapillatum, Oxydirus nothus and Dorylaimoides bulbosus (Penetrantia) —new to the fauna of Hungary. Species found for the first time since their description are C. gracilis, D. macroproctus, Ischiodorylaimus cognatus, Crocodorylaimus fusus, A. pycnus, A. samarcandicus, M. aquaticus and O. nothus. The two most abundant species in the national park and its environs are A. obtusicaudatus and Anaplectus granulosus (ANDRÁSSY 2002). A Hungarian muskrat (Ondatra zibethicus) collected near Fertő yielded a single female specimen of Capillaria sp. An Ascaris sp. larva was found in material in the Hanság (SEY 1965a). Several specimens of Angiostrongylus dujardini were found in the lungs and hearts of small mammals (Apodemus flavicollis, A. sylvaticus, Clethrionomys glareolus and Microtus subterraneus) collected in the Sopron Hills and Sopron district (at Tómalom— MÉSZÁROS 1972). The same numbers of host animals were collected at each site, so that the strong difference in the incidence of Angiostrongylus dujardini in the two places can be explained by the quantitative and qualitative differences in the populations of the snails that act as intermediate hosts. The specimens of root vole (Microtus oeconomus) proved to contain Mastophorus muris (Fertőboz and Barbacs: Barbacs Pond), Boreostrongylus minutus (Hanság: Lake Fehér) and Syphacia nigeriana (Sopron: Kis-Tómalom, Lake Fehér and Barbacs: Barbacs Pond —MATSKÁSI et al. 1992). Faunistic investigations of the FertőHanság National Park, along with published data and earlier and more recent collections show that 6 species of nematode parasite are found in mammals in the national park and district (GUBÁNYI et al. 2002d).
