Abstract
The' fly-round' for estimating the density and fluctuations of tsetse populations was developed by Potts (see Nash, 1930), and a number of such rounds were established at Shinyanga in various blocks of bush catrying Glossina swynnertoni. The actual number marked out in each block varied from one to five, according to the size of the area being examined. The catchers, carrying black screens, as described by Swynnerton (1936, p. 35), traverse each round twice or four times a month, and from their catches is calculated the , apparent tsetse density,' expressed as the total number of flies caught per 10,000 yards (Swynnerton, 1936, p. 34). Harrison (1936) has published a map showing the various blocks.
