Approximately 90 village Ethiopian Highland Zebu cattle at Gullele in southwest Ethiopia were ear-tagged in March 1986 and they and their offspring monitored monthly until February 1996. In January 1991 a tsetse control campaign began using a synthetic pyrethroid cypermethrin pour-on applied mont...

Methods for determining the efficacy of animal health interventions involving vector-borne diseases when the intervention attempts to control the vector itself are described. There are a number of possibilities. For example, a before/after study can be undertaken when data collected following the...

Evaluates the productivity of different breeds of cattle, sheep and goats, particularly trypanotolerant breeds, exposed to different degrees of tsetse challenge under various management systems in 9 West and Central African countries and in three associated East African countries, w. the objectiv...
Examines the proboscides, midguts and salivary glands of live tsetse species for trypanosomes trapped at forest edges, inforest close to watercourses and at the boundaries of savanna and pastures in Gabon to confirm the existence of a considerable trypanosomiasis risk due to the high infection ra...

Reports the feeding preferences of Glossina species at sites of the African Trypanotolerant Livestock Network. Estimates tsetse challenge and relates the results with trypanosome prevalence in cattle. Examines the relationship between tsetse challenge using linear regression analysis. Also examin...

Tsetse feeding habits and tsetse challenge at sites of the African Trypanotolerant Livestock Network
For at least five decades, tsetse biologists have observed that the populations of some species of tsetse (particularly species in the morsitans group of flies) decline as fly habitat is converted into cultivated land and host populations are decimated by hunting. Some have even suggested that ts...

Will human population growth and land-use change control tsetse during our life times?
Herd-to-herd variations in the primary biological impact of an intervention can sometimes be utilised to investigate secondary impacts. This approach has been used in the analysis of the effects of tsetse control on calf live weight gain. Nineteen herds of cattle were monitored in the region of B...
