Abstract
It has been shown experimentally from three repeated infestations that dogs were unable to develop effective resistance against dog ticks: Rhipicephalus sanguineus Latreille, 1806 and Haemaphysalis leachi leachi Audouin, 1826. The number of successive engorged females recovered from dogs at the second and third infestations in both species were not significantly less (P>0.05) than the number recovered at the first infestation. There was also no significant difference in body weight, body dimensions (lengths and breadths) ofengorged females, feeding periods, pre-oviposition periods or egg weight. In-depth studies of host-tick vector
interaction and examination of immunobiological parameters involved in order to develop strategies for better, cheaper and safer tick control in dogs as an alternative to the use of acaricides is suggested.
