Hosts : In all parts of the world A. persicus appears to be pre- 

 eminently a fowl tick. It commonly attacks man in Persia, where, at 

 an early date, it had acquired a most evil reputation. In South Africa, 

 Lounsbury (1903, p. 11) states that it also seriously infests ducks, geese 

 and turkeys, and that he has on several occasions found a few adults in 

 pigeon-coops. But a few were attracted to feed on pigeons under 

 experimental conditions. It has been reported from Graaff-Reinet 

 as killing young ostriches and from Grahamstown as attacking canary 

 birds. A gentleman at Graaff-Reinet suffered once from a severe bite. 

 Neumann (1896) and Ward (1900 a) state that the tick has been found 

 on quail and Packard (1895) on turkeys in California, and according to 

 Salmon and Stiles (1901, p. 405), Packard found it once among 

 Boophilus anmdatus which had been collected from cattle. The larvae 

 have been found on the wild dove (California) and on Zenaidura 

 macroura L. (Mexico). Riley and Howard (1893, p. 267) state that the 

 fowl tick attaches itself chiefly under the wing and shoulder of infested 

 hens.
