Prevalence of trypanosomiasis in cattle in South-West Zambia

Abstract

A trypanosomiasis survey was conducted in South-West Zambia. From a total of 3,346 cattle sampled 342 cattle showed a positive trypanosomiasis parasitaemia. During the survey trypanosome species and PCV values were also recorded. With simple statistical analysis populations with higher and lower prevalence rates were differentiated. The results indicated that the Kwando River Basin Tsetse Fly Belt and the Kafue River Basin Tsetse Fly Belt infested a larger area than originally assumed and that a link-up between both belts occurred or will occur in the near future.

“…Por outro lado, os resultados aqui obtidos estão próxi-mos daqueles observados em regiões com clima e manejos semelhantes àqueles encontrados nas mesorregiões do presente estudo como relatado por Corten(1988), que obteve 10,22% de positividade em inquérito realizado na Zambia, e por Connor & Halliwell (1987) que encontraram 17% de prevalência de T. vivax, na Tanzânia.…”

A trial of odour baited targets to control the tsetse fly, Glossina morsitans centralis (Diptera: Glossinidae) in west Zambia

“…1). The area forms part of a tsetse belt which, since the early 1950s, has been expanding from the Okavango delta in Botswana, through the Caprivi Strip and along the Chobe, Kwando and Zambezi rivers into Angola and Zambia (Jordan, 1986; see also Corten et al, 1988). G. m. centralis is the only tsetse fly present.…”

“…The use of targets that are coated with insecticide and provided with odour attractants has become one of the main methods of controlling tsetse flies, Glossina spp., in Zimbabwe (Vale et al, 1986, 1988 and should find useful application elsewhere. In the Western Province of Zambia game fences and aerial application of insecticides (Evison & Kathuria, 1984;Park et al, 1972) have been used to control Glossina morsitans centralis Machado in the past but neither method proved sustainable.…”
