SUMMARY Brahman x Hereford cattle carried only one‐quarter as many engorging adult bush ticks ( Haemaphysalis (Kaiseriana) longicornis ) as Hereford, Simmental x Hereford or Friesian x Hereford cattle when grazed together on the north coast of New South Wales. Fourteen percent of a Brahman x Hereford herd carried half of the engorging ticks suggesting that infestation levels would be further reduced by culling procedures. The results indicate an additional advantage to those already established for Brahman x Hereford cattle on the north coast of New South Wales and have important implications for tick control.
