The specimens were examined at the Institute of Veterinary Research in Anyang, Korea R. and were identified as Rhipicephilus sanguineus (Latreille 1806). The morphological characteristics observed by means of the scanning electron microscope were presented with some SEM microphotographs. As R. sanguineus was firstly discovered to occur in Korea R, a total of 20 species of ticks belonging to 8 genera such as Argas, Amblyomma, Boophilus, Dermacentor, Haemaphysalis, Hyalomma, Ixodes and Rhipicephalus has now been recorded

Despite of presence of a wide choice of antihelminthics, in the Republic of Belarus it is still a real problem of development of preparations that provide long-term treatment and preventive maintenance efficiency against helminthosis. At the same time, helminthes and anthelminthics render the immunosuppression action. The solution of this problem can be a combined application of antihelminthics and adjuvants. There were proposed preparations Albepolis and Averpolis. Their application made it possible not only to release an organism of animals from parasites, but also to correct the state of immune system. The obtained research data confirm the available data about the immunosuppression action of parasites on an organism of animals. There was also is noted the immunosuppression action of Albendazol and Aversektin C in therapeutic doses. Albendazol possess a wide spectrum of action against trematodes, nematodes, cestodes. It interrupts the metabolism, oppresses fumarate reductase activity and adenosine triphosphate synthesis of a parasite. It proved to be low-toxic for homoiothermal animals. Albendazol rendered positove influence on growth, development and increase of cattle productivity.

In the conditions of the Republic of Belarus there were determined the parameters of acute and subacute toxicological characteristics of the developed in the Vitebsk State Academy of Veterinary Medicine anthelmintic preparations of durable action Febolvetum-О for control of sheep strongylatosis and Febolvetum for control of strongylatosis of cattle young stock. Data on determination of toxicological parameters of the prolonged action bolus were presented. Research results showed that the preparations did not render negative influence on laboratory animals (white mice). According to the parameters of acute oral toxicity the Febolvetum was qualify as the third hazard class. In accordance with the results of study of subacute toxicity parameters of the preparations, it was concluded, that in the conditions of free feeding of Febolvetum boluse in combination with forages in course of 30 days in doses of 200 mg/kg; 150 mg/kg; 100 mg/kg of body weight in animals there were found no signs of intoxication; there were not stated any is not fixed deviations in physiological state; and were stated no mice death.

In the conditions of the Republic of Belarus there was studied the application of sodium chloride obtained by electrolysis method on Akvamed installation in a complex of activities for the preventive measures of animal helminthoses. Electrochemical activation of aqueous solution of sodium chloride proved to be a progressive and rational technology which made it possible to substantially reduce the material costs and power consumption for the development of highly efficient and ecologically safe disinvasion solution. Application of sodium chloride solution with the minimal content of available chlorine of 3,0 g/l provided the death of 94-95% of Taeniidae eggs in course of 30 minutes after applicated of the preparation on the treated surface. The proposed method can be recommended as the most efficient and economically effective for the disinvasion of external environment.
