Description of a mono-screen trap for Glossina fuscipes fuscipes Newstead in Uganda

A low-cost mono-screen trap for Glossina fuscipes fuscipes suitable for use by a rural community in Uganda is described. The trap has a single blue/black screen and a cone made from mosquito netting. The supporting framework is made from indigenous plant materials. The differences in trap catches between the mono-screen, biconical, pyramidal and vavoua traps were highly significant (P less than 0.001). Taking the standard biconical trap as control, the mono-screen trap was 1.25 times as efficient and the pyramidal trap was 0.04 times as efficient. The cost of one mono-screen trap is estimated as 1800 Uganda shillings (= U.S. $4.7), about half the cost of a pyramidal trap and one-quarter the cost of a biconical trap. The prospects for the use of the mono-screen trap by the community are discussed.
