The sequential aerosol technique: a major component in an integrated strategy of intervention against Riverine Tsetse in Ghana.
BACKGROUND: An integrated strategy of intervention against tsetse flies was implemented in the Upper West Region of Ghana (9.62°-11.00° N, 1.40°-2.76° W), covering an area of ≈18,000 km(2) within the framework of the Pan-African Tsetse and Trypanosomosis Eradication Campaign. Two species were target...
