Abstract

During the 1977/78 dry season an experiment was conducted in the Volta Noire source tributaries area of Upper Volta, to assess the feasibility of controlling human trypanosomiasis by reducing the vector, Glossina palpalis gambiensis, by a combination of techniques. The objective was to suppress the target tsetse population by chemical means and then to achieve a further reduction or eradication by the release of sterile males.

Sixteen kilometres of the fringing forest of the upper River Guénako were treated with the synthetic pyrethroid decamethrin (OMS-1998) applied from a helicopter as an aerosol at a dosage of 0.2 g/ha. Two applications at 14 days interval reduced the target G.p. gambiensis population by over 95% and caused important changes in the qualitative composition of both G.p. gambiensis and G. tachinoides populations. Subsequent over-flooding of the residual G.p. gambiensis population by sterile males was easily achieved.
