Sites of attachment of Karoo paralysis ticks (Ixodes rubicundus) on three cattle breeds.

The sites of attachment of female Karoo paralysis ticks (Ixodes rubicundus) were determined on Friesian, Bonsmara and Nguni cattle in the south-western Orange Free State. The largest proportion of the ticks (> 30%) attached to the forelegs and shoulders of the cattle. Contrary to the findings on small stock, no significant differences in the preferred sites of attachment were evident between the breeds of cattle.
