Tsetse flies (Glossina sp.) infest over 11 million square km of Africa, and are vectors of Trypanosomosis (or Trypanosomiasis) in both man and domestic livestock. For example, it is estimated that tsetse occur over 7 percent of Zimbabwe and 60 percent of Tanzania and Trypanosomosis has an important negative impact on livestock production in these areas. In addition to the use of trypanocidal drugs, the control of Trypanosomosis has been tackled largely by the control of the tsetse fly vector. A range of techniques are available, each with advantages and disadvantages. Methods include aerial spraying, sterile insect techniques, insecticide treated cattle, and odour bait traps and targets. Furthermore, it is generally considered that deployment of traps and/or targets that destroy a proportion of the tsetse population will lead to a reduction in the incidence of trypanosomosis. The following technology describes a set of simple step-by-step instructions on how to construct a cage, made from easily available plastic bottles, for use as an Epsilon tsetse trap.
