What is an ox fly-round?
An ox fly round is similar to the traditional man fly round, except that the team comprises 2-3 people with hand nets and an ox. The team walks through the bush, stopping at regular, marked stations where they collect following flies. Most flies will be caught as they land on the ox.
An ox fly round is more effective than a man fly round, but it is more logistically complex since a survey animal must be maintained in a tsetse-infested area, provided with adequate food and water and protected from large predators.
