dc.description.abstract |
1. The distribution of B. decoloratus has been given in terms of political divisions as well as in terms of vegetational coverage.
2. The factor playing the most important role in limiting the spread
of B. decoloratus is seen to be increasing aridity. In most parts of the
Union the critical level is represented by an annual rainfall of 15 in.
3. It is concluded that where farming conditions are favourable the
tick can be controlled by dipping.
4. From the nature of the data available one is perhaps not justified
in drawing any definite conclusions as to the distribution of the arsenic-resistant strain; one can but draw attention to the fact that it apparently
occurs on scattered farms throughout the tall grassland areas extending as
far north as Swaziland. |
