Box 2, Budapest, Hungary (Received 18 September, 1992) Abstract: The helminth fauna of the small field mouse (Apodemus microps Kratochvil and Rosicky, 1952) and the common vole (Microtus arvalis Pallas, 1778) was studied in a pine forest at Babat (County Pest). A total of 9 parasitic helminths were recovered from the small field mouse, which is reported for the first time as a new host of Anoplocephaloides dentata, Hymenolepis fraterna, Hymenolepis diminuta and Hymenolepis muris-sylvatici. Only well-known helminths were found in common voles, but Heligmosomum costellatum was lacking. The prevalence of parasitic helminths in the two micromammalian species remained beyond what would have been expected. A remarkable seasonal difference was observed in parasite composition by sex of the host species. Key words: Apodemus microps, Microtus arvalis, parasitic helminths, seasonal variation, weight category, pine forest, Hungary INTRODUCTION Numerous studies, mostly faunistical and taxonomical investigations, have been published on the parasitic helminths of the common vole (Microtus arvalis Pallas, 1778) in the Carpathian basin (Murai and Tenora 1973, Tenora et al. 1973, Murai 1974, Mészáros 1977, Mészáros and Murai 1979, Tenora et al. 1985).
