[Problems of the ectoparasite control in the Mongolian People's Republic].

The co-operation between G.D.R. and M.P.R. in the field of control of ectoparasites in farm animals is described. The problems under the specific conditions of the M.P.R. in the control of the principal parasitoses of economic importance such as hypodermosis, mange, tick infestations, oestrosis, vermipsyllosis, gasterophilosis and wohlfahrtiosis are analysed. The successfully applied hypodermosis control program represents the base for further systematic, state-directed strategic measures in controlling of ectoparasitoses.
