PARASITOLOGISCHE UNTERSUCHUNGEN AN ALPINEN KLEINSÀUGERN 933

SUMMARY 



; 



Between autumn 1966 and summer 1969 ectoparasitic Acari had been 

 ;ollected of small mammals of différent altitudinal zones in the Tirol (Austria). 

 46 species, most of them new for the Tirol or Austria, are recorded, for several 

 species additional information on their distribution can be given (e.g. for Laelaps 

 clethrionomydis, Myonyssus rossicus, Haemogamasus nidiformis, Hirstionyssus 

 tatricus and H. eusoricis). Laelaps clethrionomydis, Haemogamasus nidiformis and 

 Hirstionyssus tatricus only were found in the subalpine and alpine zone. The 

 average number of mites per host decreased during summer, the average number 

 of mite species on one host increased. Host-parasite-relations of some species are 

 ,discussed.
