Journal Article 1993

Autor: Leak, S.G.A. Mulatu, W.

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...

Journal Article 1999

Autor: Rowlands, G.J. Mulatu, W. Leak, S.G.A. Nagda, S.M. D'Ieteren, G.D.M.

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...

Trypanosomiasis remains the most important constraint to livestock production on the African continent. Chemotherapy, using curative and prophylactic drugs, is the main method of control of the disease in cattle. The exploitation of the trypanotolerance trait of some breeds of large and small rum...

The new pour-on insecticides that can be used to control tsetse-transmitted trypanosomiasis confer benefits to the owners of the cattle given treatments and other people keeping cattle in areas affected by the control. A study was conducted in southwest Ethiopia to assess farmers' perceptions of ...

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...

Autor: Leak, S.G.A. Rowlands, G.J.

Trypansosome infections in approximately 110,000 tsetse of 12 species or subspecies, at sites in six African countries, were studied over various periods from 1983 to 1994. Infection rates ranged from 0.2 percent in Glossina fuscipes quanzensis Pires at a site in Zaire, to 18 percent in Glossina ...
