Cost-effectiveness of using targets and cattle to control tsetse.

For each row, the days required to stabilise the tsetse distribution in Scenario L, and the costs of stabilisation are shown. The simulations assumed that insecticide-treated cattle, with a daily mortality of 10%, were deployed in all parts of the operational area, except for a central section 7 km wide where targets imposing various mortalities were started at various times in relation to the start of cattle treatments. Days to stability are counted from the start of cattle treatments.
