title: [The significance of the species classification of ixodid ticks and their hosts in the development of antitick immunity].
abstract: Larvae of Ixodes persulcatus and Hyalomma asiaticum were feeding permanently on hosts attacking them daily by groups of 5-20 ticks, and also fed by groups of 30-40 and 100 ticks with the interval 20 days. The factor of the host species in the case of 1-st feeding of ticks did not influence significantly on the weight of engorged ticks and also on the percent of larvae, which had finished the feeding and moulted to nymphs. In the cases of 2-nd and 3-rd feedings the significant part of ticks died before the end of feeding, and engorged ticks had less weight and lower capability to moult. The rate of anti-tick resistance of hosts depends upon the species of the host and upon the number of ticks fed up. In the case of permanent feeding of larvae during 40 days the anti-tick resistance was low or completely absent.
