Ectoparasites of the Irish stoat.

A sample of 196 Irish stoats Mustela ermineae hibernica Thomas & Barrett-Hamilton (Carnivora: Mustelidae) were examined and yielded 2580 arthropod ectoparasites, including 1819 larval mites Neotrombicula autumnalis (Shaw) from a single host. Other ectoparasites recovered included lice (99% Trichodectes ermineae (Hopkins], ticks (mostly Ixodes hexagonus Leach) and four species of fleas. The ticks and fleas were considered to have come mainly from nests of other hosts. The flea species did not reflect the status of their usual hosts in the diet of stoats, but did reflect the stoats' use of their usual hosts' habitat.
