Experiments in Tsetse Control in southern Tanganyika

A recent extension of the fly-belt in Songea, southern Tanganyika, has been delimited. The preferred habitat of the tsetse in this region is constituted by open, short-grassed glades, representing old village sites, in well-grown Brachystegia woodland, with a double-canopied interzone between glade and woodland. Destruction of this interzone by clearing of the upper canopy will undoubtedly prove effective in causing eradication of the fly.
