Abstract : In Rh. sanguineus and Rh. turanicus, which develop with a change of 3 hosts, larvae feed well on rabbits, guinea pigs, white mice, and hedgehogs. The first two host species and hedgehogs may be utilized for mass feeding of nymphs in experimental conditions. In contrast to Rh. sanguineus, Rh. turanicus larvae engorged in a shorter period on white mice and their nymphs in a shorter period on hedgehogs. The surrounding atmospheric temperature and the season of feeding did not effect the engorgement period of immature stages of either species. These factors also noticeably reflected on periods of oviposition and moulting of larvae into nymphs. Minimal periods of the entire developmental cycle under the stated conditions were 67 (Rh. turanicus) and 73 (Rh. sanguineus) days, not including the period necessary for the adult tick to acquire the ability to suck blood.
