The distribution of O. megnini is given in terms of political divisions, as well as in terms of vegetational coverage. 2. The factor limiting its distribution appears to be high rainfall. The tick has probably not yet been introduced into all areas of the Transvaal. 3. Seven day dipping has been shown to control the tick in some districts. 4. No seasonal periodicity was observed.en© 1958 ARC - Onderstepoort and Faculty of Veterinary Science, University of Pretoria (original). © 2016 University of Pretoria.
