Nymphs and Adiilts 



pe 



Specimens from the Kittd. District of Kenya (Heisch 1954F) 

 were determined by precipitin tests to have fed on porcupines 

 and not on hyraxes, rats, or gerbils. Lizards and baboons were 

 suspected as possible hosts. Subsequently, Garnham (1954.) worlc- 

 ing in the same sirea fovmd blood corpuscles of lizards in re- 

 cently fed ticks and noted that undigested corpuscles could be 

 identified in the ticks at leaist a month after feeding. Garnham 

 fed captive nymphs and adults on geckos and agamid lizards. 



Inasmuch as nymphs and advilts feed rapidly, they are seldom 

 found when the vertebrate host is examined. It may be assxnned, 

 however, that these stages probably feed on most of the larval 

 hosts noted above. 



Walton (I95OB) reported that Brumpt's argas attacks hyraxes 

 and people who take refuge near hyrax dens in Kenya. T heller's 

 five female specimens from Ovamboland are from a mierkat, Cynictis 

 nicillata Cinderella . Africans of the Yatta Plains say that 

 his tick (kitionuj feeds on human beings, elephants, buffalo, 

 elands, and giraffes, and that specimens may be fovmd in dust 

 where big game animals roll (Cunliff e 191AB) . I have seen three 

 adult specimens from a lion's lair near Pusa, Kenya (HWH collec- 

 tions). In Ethiopia, Brumpt found A. brumpti near porcupine bur- 

 rows, and reported its bite on himself ^Nuttall et al 1908. 

 Brumpt's Precis). King's (1915) Sudan records are Trom sparsely 

 vegetated areas containing caves and crevices in which many kinds 

 of animals rest. Uganda hosts are the African porcupine and the 

 rock hyrax, Procavia capensis meneliki (Hoogstraal and Kaiser 1956). 



Experimental Hosts 



King (1926) reared larvae on the bare skin of the head of 

 giiinea fowl. Larvae failed to engorge on man, dogs, cats, goats, 

 pigeons, doves, sparrows, or bats, though some attached to spar- 

 rows and pigeons. Nymphs and adults fed on rabbits and man. 

 Ruttledge (1930) foiind no larvae on guinea fowl in the Nuba Moun- 

 tains and believed that lizards are the favorite larvsil host there.
