Trypanosomiasis is one of the most severe livestock diseases in Africa: over 45 million cattle and 100 million sheep and goats are exposed to the disease across an area of 10 million km2. In south-west Ethiopia, at least six million cattle are at risk of contracting the disease, and recent reports indicate that the area infested by tsetse flies is expanding. To make matters worse, the parasites that cause trypanosomiasis have become resistant to all the drugs available for treating the disease. Four years ago, scientists from the International Livestock Centre for Africa (ILCA) and the International Laboratory for Research on Animal Diseases (ILRAD) decided to test the cypermethrin-based new pour - on tsetse suppressant. This is applied by pouring the liquid formulation along the dorsal line of animals from neck to tail. Ciba-Geigy supported the trial with their product since there had been no published reports of effective use of thicypermethrin formulation (known as cypermethrin high-cis) for this purpose. During the first two years, treatments were given free of charge. All livestock owners living between the villages of Gullele and Tolley were invited to bring animals (or treatment. The density of tsetse flies (Glossina pallidipes. G. morsitans and G. fuscipe) gradually declined, as did the prevalence of trypanosomiasis in the 100 cattle that were monitored each month. Almost all (97%) of the cattle owners in the area volunteered to have their cattle treated some time during the first two years. According to the farmers, the main advantage of the pour-on was that it kills zimb (biting flies including tsetse) and reduces the incidence of ghendi (trypanosomiasis). They also reported other advantages such as fewer problems with ticks, quieter animals during grazing and milking, faster healing of wounds, and improved body condition. The pour-on is expensive three Ethiopian birr per treatment, which is enough to hire a casual labourer for a day - but the farmers saw for themselves that the benefits far outweighed the costs. Between December 1993 and October 1994, 30% more treatments were given than during the same period the previous year. Dr Brent Swallow ILRI PO Box 46847, Nairobi, KENYA
