Ticks respond to host stimuli, such as higher CO₂ concentrations, vibrations, odour, touch, radiant heat ad kairomones. The behahaviour al reactions to these host stimuli vary among tick species. Among these arthropods hunter (actively running in the direction of host) or ambusher ticks (passively waiting for host on the vegetation) occur. Hallers organ. palpal organ, cheliceral organ and receptors on scutum and alloscutum are involved in tick feeding behaviour.
