Host location and feeding among ticks involves positioning for host findings, probing, attachment, imbibing blood and thereafter detachment. Different species of ticks fulfil this sequence of events in different ways. Behavioural differences are mainly due to sensory inputs obtained by a tick and the processing of that input by the central nervous system. Tick receptors responsible for perceiving stimuli originating in the general environment and the host in particular are located on the tarsi and mouthparts. This review gives a brief account of current knowledge on sensory receptors involved in the above behavioural patterns.
