Abstract

Case studies, mainly in Zimbabwe but also in Zambia, investigated economic aspects of controlling savanna species of the tsetse fly (Diptera: Glossinidae) which is the vector of bovine trypanosomiasis in southern Africa. Costs for the four major techniques for tsetse control, each of which has been used on a large scale in the recent past, were analysed on a comparative basis. The costs of using odour-baited insecticide treated targets compared well with traditional ground spraying using DOT, which is increasingly disfavoured on environmental grounds. The cheapest method of tsetse control is to treat cattle with appropriate insecticides. There are many situations where this is not feasible, for lack of cattle, but the approach is generally very promising and needs urgent technical development. Although aerial spraying is likely to be the preferred method for tsetse control in some specific situations, it is the most expensive of the four techniques which were evaluated. Case studies showed that the policy of the Government of Zimbabwe was justified in relying upon tsetse control rather than the use of trypanocides. However, the comparative advantage is variable according to specific circumstances. A methodology for cost comparison has been developed and demonstrated, based upon simple economic models usable by planners without formal economics training. The emergence of bait techniques provides an opportunity for innovative strategies for tsetse and trypanosomiasis control in southern Africa, in which tsetse operations involve local communities and co-ordinate with rural development more closely than in the past. There is a key role for the economics profession in assisting to ensure that co-ordination is effective and appropriate.
