Tick infestation (Ixodes) on feral mink (Neovison vison) in central Germany


Abstract

Four  species  of  ticks  (I. hexagonus, I. rugicollis, I. canisuga, I. ricinus)  were  found  to  infest  feral American mink (Neovison vison) in central Germany. About 45 % of all investigated mink were infested. The  most  common  tick  species  on  mink  was  I. hexagonus.  The  prevalence  =  infestation  extensity (proportion of infested animals) with I. hexagonus was 43.8 %, which is approximately in accordance with the infestation extensity in England and Wales (40 %). The average infestation intensity (number of ticks per infested animal) is 11.0 ticks per infested mink. Two species of ticks were found on 10.9 % of the infested minks. The highest infestation intensity of I. hexagonus found on one mink was 43 larvae plus 7 nymphs. The average infestation intensity of the stages of I. hexagonus was 4.42 females, 5.91 nymphs and 8.26 larvae per mink. In the investigation areas in central Germany the mink is proved to be a frequent host for I. hexagonus. The frequent common wood tick I. ricinus parasitised only rarely on mink.
