mammals from the Tilrnasjii and Amrnarnils areas in

Swedish Lapland

By ANonns Eor.Bn

l. Introduction

very little has been published on the parasitic mites of the small mam- mals of Scandinavia. During the last seven years much material has been collected by working groups from the Department of Animal Ecology, Uni- versity of Lund, as a parf of the department's research on small mammals and their ectoparasites.

The present paper deals with material collected in the Tiirnasjii and

Ammarnhs areai, Lycksele lappmark, in Swedish Lapland during the years 1968-1966. The coilectors were: A. Pettersson, C. Riideberg and L. II. Wiss

(15/6-30/6 1963); H. Andersson, P. H. Enckell and B. Hylt6n-Cavallius

itzlt-rctt 1963); G. & P. Brinck, L. Cederholm and I. Rudeheck (4ls-fi19

igos) ; H. E. Lindskog (1616-1017 1963, 1216-917 and 6ls-rgls 1964) ;

S. Ulfstrand (4/7-11181963, 15/5-2315 lS64); P. Brinck and L. cederholm (28/6-80/6 tbO+); L. Hansson (1216-1616 1964, 1716-2716 1965, 1516-2016 1e66).

2. Material antl methods

1,651 small mammals were collected. Ectoparasitic mites were found on 518 host animals, 49 of which were dead when removed from the traps.

2,688 specimens of parasitic mites were collected from the fur of the mam- mals. 2,379 were from live mammal specimens.

The mammals were collected in net cage traps (Hansson 1967), placed

in plastic bags, killed with ether and injected with 10 ml- formalin-alcohol (1 part 4 0/o formalin and 1 part 80 0/o ethanol) . About 30 ml formalin-alcohol rvas poured in each bag.

TIie ectoparasites were removed in the laboratory and prepared for micro- scopic examination in Swan's medium, Kramar's modification (Hrbacek

et al. 1954).

Most of the material was determined by Dr. Milan Mrciak, Zoological Institute, Bratislava during his stay at the University of Lund.

It is known fronl many parts of the world fronl various host aninlals (Strandtmann andヽ γ harton 1958)and iS fOund in nests of most small mam―

mals in Europe(NIrciak 1959 b). Trigirdh (1931)found it in a hay‐ loft at the Faeroes. It easily adapts itself to various ecological conditions and to

various host anilnals. It can attack man and nlay be a vector of diSeases (MrCiak 1958 b).

'fhe species was found on Sorer eraneus, Clethrionomgs glareolus, C. ruf o- cenus, llicrotus agrestis, Lemmus lemmus and, Mustela ntinutcr. It was most common on C. rufocanus, 84.1 0/0. Only 9.4 0/o were collected from C.

glareolus.

'Ihis mite is of interest because of its adaption to particular hosts in dif- ferent zoogeographical areas. In czechoslovakia and Bulgaria the main host is Clethrionoru.gs glareolus (Mrciak 1959 a-b).

Hg perlaelaps arualis Zachvatkin, 1948

The species was found on clethrionomas glareolus, c. rulocanus, ilIicrotus agrestis and Lemmus lemmus. 84.8 0/o of the specimens were found on M. ogrestis.

According to Mrciak and Brander (1965) the main host in central Europe is Microtus aruolis Pallas, but this species does not occur in North Finland

or Scandinavia except for Jutland. Mrciak and Brander (1g65) found one specimen on XI. agresfis in Finland.

Mg ong ssus inglricus Bregetova, 1g56

Two females were found, one on sorer araneus and one on Microtus agrestis.

The mite has been found on many different hosts. It is rather rare on small mammals (Mrciak 1958a,c, Mrciak and rovornik lgbg), but more common in their nests (Willmann 1952).

The species was previously known from three countries, viz. Czecho- slovakia, Yugoslavia and Bulgaria. There the main host is l'licrotus niualfs Martins (Mrciak 1959b) which does not occur in Scandinavia. H. tatricus was found only in mountain districts.
