HOSTS 



Like the subspecies simus , R. simus senegalensis attacks a 

 variety of larger game and domestic animals. The imraatxire stages 

 probably feed on rodents, but no data concerning their host pref- 

 erences are available. 



Domestic animals ; Cattle (Z\impt 1943 A*, Rousselot 1951 > 

 1953B, Unsworth 195^, Rageau 1953B, Hoogstraal 1954C**). Horses
