Sequential feeding of Ixodes rubicundus on its natural host, Elephantulus myurus: effects on tick mass and on engorgement and moulting success.

Engorgement, mass at repletion and moulting success of immature Ixodes rubicundus after sequential infestations of their natural hosts, rock elephant shrews (Elephantulus myurus), were investigated under laboratory conditions. The reaction of E. myurus is characterized by inefficient or non-existent anti-tick immunity which enables immature I. rubicundus to attach and engorge successfully and ensures a high moulting success rate.
