Popis:	Amblyomma hebraeum differs from many ixodid tick species in that it is not susceptible to the direct effects of the host immune response. All stages of the life cycle are able to feed repeatedly on laboratory hosts and show no progressive declines in engorged weight. However, on cattle there are declines in the yield of engorged adult females over time, as animals become sensitized to the tick and grooming increases. In the field zebu, Bos indicus and sanga, B. indicus x B. taurus breeds of cattle become less heavily infested than B. taurus breeds. The apparent resistance of zebu and sanga breeds is the result of learned tick avoidance behaviour, skin sensitivity and the ability to dislodge ticks prior to attachment as well as grooming ability. Among other Amblyomma spp., the feeding of A. americanum is adversely affected by acquired host immunity, while that of A. variegatum is generally unaffected.
