According to Poraerantzev (l93/k) hosts of the immature stages 

 in Armenia include reptiles and wild birds. The fatty sub- 

 cutaneous layers of ground squirrels, Gitellus sp., used as 

 laboratory hosts (Pospelova^Shtrom 193"j, may IrLnder the attach- 

 ment and feeding of larval H. dromedarii (= H. yakimowi ) . 



In Russia (Pomerantzev 1950), adult hosts are camels, horses, 

 and sheep while nymphs feed in large numbers on cattle and camels. 

 Hosts of adults of the synonymous H. asiaticum are camels, cattle, 

 horses, and sheep; rarely donkeys, "goats, domestic and wild pigs, 

 hares and hedgehogs; sometimes man. l!;,'7aphs of this latter form 

 occur on hedgehogs, in burrows of large "peschanld." aJid gophers, 

 while larvae are often on hedgehogs. Both immature stages are 

 foiind (?together) on hares, gophers, jerboas, "peschanki", cats 

 and dogs, and single nymphs are found on cattle and sheep 

 (Bogoroditsky and Bernadskaia 1938). 



BIOLOGY 



Life Cycle 



The question of the normal number of host? of K. dromedarii 

 is moot. Delpy and Gouchey (1937) consider it as a""three_host 

 tick that may utilize only two hosts under unfavorable conditions; 

 i.e. great heat, when larvae molt quickly and reattach as nymphs 

 nearby on the same host in order to avoid desiccation. It would 

 appear that normally, on biorrowing mammals, this need would not 

 arise since the hosts venture from their relatively cool tunnels 

 only after the sun goes down (deserts are usually cool at night).
