HOSTS 



Cattle are the chief host of the blue tick and most papers 

 listed in DISTRIBUTION above refer mainly to this animal and ef- 

 fects of this tick*s feeding upon it. Domestic horses and, less 

 frequently, sheep and goats are attacked. Among wild animals, 

 antelopes are in5)ortant hosts but few others are infested. Wild 

 carnivores are almost never parasitized by this tick. This is a 

 single host tick, therefore hosts of the immature stages are the 

 same as those of adults.
