Causes of mortalities observed in caviaculture are badly known even ignored by breeders in Sud-Kivu precisely in Walungu area. Thus, we contemplated to have a study in order to characterize ectoparasitosis in this breeding by emphasizing on their symptoms, the identification cutanous scratching and harvest of crust and hair of guinea-pig submitted on the laboratory analysis, suggesting some recommendation especial hygienic adapted to the small breeders in the peasant area by taking into account a test of heal with palmist oil associated with kerosene. All that in order to manage the risks of infestations which can harmer even human beings, because these sicknesses are wellknown as zoonoses. Our study was applieds in this center of Walungu area where we have first isolated the sick guinea-pig on which we took away cutanous scratching product and hair on animal met and having symptoms of scabies wiich guinea-pigs constitute the fist pattern. The second lot constitutes the hair harvested on guinea-pigs in the pilot farm, in order to characterize ectoparasites by identifying in laboratory where we have put our emphasis of ectoparasits Sarcoptes scabei and Demodex sp type but as well their frequency which vary according to different farm, ages and sex. Notice that the breeding system which remains traditional is at the origin of dissemination of these ectopasasits mainly if some hygienic rules are not respected. They are the purchasing in the market or in the farms infested, the donation followed by sudden introduction of guinea-pigs in inhurt breeding without quarantine at fist and lack of heal application of these parasits which attack human being. The sanitary care taken for in a mix of 70% of oil and 30% of kerosene renew heath of beasts.
