The fight against the tsetse fly (Glossina spp.) which spreads trypanosomes that cause sleeping sickness is still being fought, with insecticides. But the pyrethrum-based insecticides in use today are less powerful than the more environmentally harmful DDT which they are supposed to replace. Another control method is to impregnate livestock by means of baths or sprays, so that they become living traps for the flies. Biological control does not offer any practical applications at present, but the release of sterile male tsetse flies, alongside the use of insecticides, does work, albeit in a delayed way. Trapping is another method, and is simple and benign to the environment; it does, however, need the participation of local communities to install and maintain the decoy traps. The method involves putting up blue or black screens which have been impregnated with acetone or phenol, and have a small cage trap above the screen. The tsetse are attracted by the colour and the smell, and are easily trapped. A anti-sickness vaccine is being developed, whereby the resistance of livestock to parasitic infection is reduced, although it does not stop them catching sleeping sickness. Finally, remote sensing techniques and field studies are providing data for identifying the most conducive environments for the flies to proliferate, and for studying their distribution.
