Vegetation and the importance of insecticide-treated target siting for control of Glossina fuscipes fuscipes.
Control of tsetse flies using insecticide-treated targets is often hampered by vegetation re-growth and encroachment which obscures a target and renders it less effective. Potentially this is of particular concern for the newly developed small targets (0.25 high × 0.5 m wide) which show promise for...
