Two blocks were isolated by 3– or 4–mile clearings on a small river with a narrow strip of riverine bush and a low density of Glossina palpalis fuscipes.
Catchers at the rate of 6 per 1,000 yards of stream caught almost all the G. palpalis in one block in 3 months and all in 6 months.
Eight months later there was ho reinfestation.
All this time G. palpalis persisted in the Control Block.
An area from which G. palpalis was removed by hand catching 10 years ago was examined. It is concluded that it is possible not only to hand catch all the G. palpalis but also to avoid reinfestation.
Hand catching is the quickest and cheapest known method of reclaiming streams of this type from G. palpalis.
Vegetational descriptions are given.
