A yariegatum were the only ticks on four pigs. At Torit, several 

 adults of R. s. Sims could be found on each pig whenever a search 

 was made and ^ were collected along with single males of R. e. 

 evert si and R. s, sanguineus. - - 



DOGS 



Dogs maintained by the few Europeans previously living in 

 Equatoria Province were deticked every day or two and yielded 

 the same species found on pie-dogs. Infestations of pie_dogs, 

 oi ten tremendous, were characterized by preponderence of R. s 

 sanguineus in practically every coUection throughout the~Prov 

 mce, smaller numbers of R. s. simus almost everywhere, and a 

 paucity of H. 1. leachii . T'Ee T^^named tick, which in Equa- 

 toria Province appears to be laore common on dogs at high alti- 

 tudes, IS represented by about U5 specimens, but the subspecies 

 H. 1. muhsam by only a single specimen. In Eastern and Torit 

 Districts, A lepiduin and R. pravus parasitize dogsj near the 

 Nile a few adults of R. simus senegalensis have been taken. A 

 single female B. decoToratus was found at Gilo. The localization 

 of A. yariei^atum infestations is of some interest. This ubiqui- 

 tous tick^T^i^^und on dogs only at Katire and Kajo Kaji. Both 

 localities are at higher elevations than the plains and received 

 less attention than Torit and the surrounding country. 



CATTLE 



Cattle are so frequently of considerable importance in sut^ 

 porting and transporting large numbers of ticks of known or pot^r^ 

 u -.r V ''^ ^^ veterinary importance that special consideration 

 should be given to cattle history, breeds, numbers, husbandry, 

 and movements wherever a tick survey is attempted. 



Before the devastating slave raids of the nineteenth century 

 cattle were more numerous in areas bordering the Nile than now. 

 Since the low ebb of that period, herds of livestock have varied 

 greatiy^due to epidemics, encroachment of tsetse flies, and 

 intertribal relations. The largest cattle populations occur in 

 Eastern District, eastern Torit District, and the Kajo Kaji area. 

 Elsewhere small herds are maintained in isolated situations but 

 west of Yei cattle are rare indeed.
