Tsetse fly populations have been monitored since January 1986 in two areas of the Ghibe valley in southwest Ethiopia, in order to assess trypanosomiasis risk to cattle. The two study areas are Abelti/Ghibe and Gullele/Tolley. Two species of tsetse fly were detected in the valley from 1986 to 1992...

African animal trypanosomiasis constaints the production of milk, meat and animal traction across much of sub-Saharan Africa. The tsetse-transmitted disease is particularly important in Ethiopia where at least six million cattle are exposed to the disease. In 1000 a trypanosomiasis control progra...

A tsetse control campaign was started in January 1991 using a synthetic pyrethroid cypermethrin `pour-on' applied monthly to cattle exposed to high levels of drug-resistant trypanosomes in the Ghibe valley of southwest Ethiopia. In December 1992, a cost-recovery scheme was introduced, and thereaf...

Few studies of land-use/land-cover change provide an integrated assessment of the driving forces and consequences of that change, particularly in Africa. Our objectives were to determine how driving forces at different scales change over time, how these forces affect the dynamics and patterns of ...

Cattle raised in the Ghibe valley of southwest Ethiopia are exposed to medium to high levels of trypanosomiasis risk and are often given trypanocidal drugs. A benefit-cost analysis was undertaken to evaluate the financial and economic returns generated by cattle raised in the area under a systema...

Tsetse populations and trypanosome prevalence in cattle were monitored from 1986 to 1993 in the Ghibe valley, south-west Ethiopia. From January 1991 to December 1993 between 2000 and 4000 cattle were treated at monthly intervals with a synthetic pyrethroid insecticide, cypermethrin (RS-alpha-cyan...

Reports results of a study on the relationships between tsetse challenge and trypanosome prevalence in trypanotolerant and susceptible breeds of cattle. Presents data on tsetse challenge and trypanosome prevalence in N'Dama and Zebu cattle in Zaire, Gabon, Ethiopia and Cote d'Ivoire.

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...

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...

A tsetse control campaign using an insecticidal cypermethrin "pour-on" applied monthly to village Zebu cattle in Ghibe in southwest Ethiopia has been in operation for over six years. For four of these years farmers have paid a cost-recovery price for each animal given treatment. Relative densitie...
