Five parasitic species were observed, Rhipicephalus bursa predominates with 45%, Rhipicephalussanguineus : 10%, Rhipicephalusannulatus 15%, Hyalommamarginatum 13% and Hyalommaanatolicum: 17%. Moreover, the prevalence of babesiosis in local horse breeds was determined. A global prevalence of 70% was found for equine babesiosis in the two areas (Sedrata and Lake of birds). The horses were found positive (Giemsa coloration) for Theileriaequi and Babesiacaballi . No significant differences were encountered concerning sex and age of infected animals. Removal of ticks manually does not prevent for ticks infestation and the exposure of horses to piroplasmosis. So, apart from favorable climatic factors, the presence of horses with other animals (ruminants and dogs) appears to be a factor in the infestation of horses by ticks. There were no significant differences between the positivity to Babesia with the factors sex and age of the horses (p>0, 0.5). After this preliminary work, a wider study of ticks of the equine population in Algeria is essential for the establishment of a plan of prevention against these mites and the diseases that they transmit.","PeriodicalId":398929,"journal":{"name":"Scientific Journal of Veterinary Advances","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125836075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

(Acarina: Ixodidae), especially during the rainy season. The IPM programs against this ectoparasite undoubtedly require knowledge of its bio-ecology and diversification of means of control. Thus, the toxic effects of the essential oil of Clausena anisata Hook (Rutaceae) diluted in two vegetable oils were tested on eggs and larvae of A. variegatum under the laboratory conditions of the temperature from 22-25°C, relative humidity from 78-91% and a photoperiod of 12 L/12h D. Toxicity tests were carried out in Petri dishes containing Whatman paper on which various test solutions were deposited. In each treated dish, 100 eggs or 40 larvae were released. A dose of 0.124 µL / cm² of a dilution of the essential oil of C. anisata prevented the hatching of 95% of the eggs and provoked 60% mortality of the larvae after 24 hours of exposure. Although these results differ significantly from those of the reference acaricide bayticol which is very highly toxic, the essential oil of C. anisata could be considered very toxic to the preimaginal stages of the tick A. variegatum . However, the cost of treatment with the essential oil of C. anisata should be evaluated to better assess its use in the control of A. variegatum by farmers.","PeriodicalId":398929,"journal":{"name":"Scientific Journal of Veterinary Advances","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123410981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
