[Differences between murine rodent species as food hosts for ixodid tick larvae (Ixodidae)]

Tests on the feeding of larvae of Ixodes persulcatus and I. ricinus on five species of Muridae have shown that forest and common voles have congenital protective reactions limiting the number of successfully fed parasites. Such congenital resistance is practically absent in common field mice and does not arise during the following parasitism of ixodid larvae. The congenital resistance is absent from steppe lemmings too but protective reactions limiting the number of successfully fed larvae arise during the further parasitism of ticks.
