Observations on the relative attractiveness to Glossina pallidipes of different animal baits, a tsetse trap, and a fly-round patrol.

Studies conducted in the Lambwe Valley, Kenya, have shown that in the absence of wild hosts, Glossina pallidipes was more attracted to a calf than to a sheep, a goat, a man, or a tsetse trap, although the latter attracted more flies than the nonbovid baits. Other investigations have shown that a newly developed tsetse trap was much more efficient at catching G. pallidipes than a standard fly-round patrol technique. An added advantage of the trap was that the sex ratio of flies caught by it was more representative of that existing in the fly population. Fly-round patrols always caught many more male than female flies.
