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...

Cette etude examine la production de troupeaux bovins villageois principalement trypanotolerants, dans la region de Boundiali, au nord de la Cote d'Ivoire. Le but est d'evaluer la rentabilite de ce systeme de production dans une region affectee par la trypanosomose et d'identifier les principales...

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...

In order to assess the effect of tsetse control on livestock productivity, 21 herds of cattle of N'Dama, Baoule and Zebu cross breeds in the region of Boundiali, northern Cote d'Ivoire, were monitored monthly for trypanosome prevalence, packed red cell volume (PCV), body weight and reproductive p...

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...

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 ...

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.

A deltamethrin `pour-on' insecticide was applied monthly to over 2000 cattle exposed to a high challenge of drug-resistant trypanosomes and high tsetse re-invasion pressure in the Ghibe valley, south-west Ethiopia. Blood samples were taken monthly from an average of 760 cattle for determination o...

Describes the epidemiology of bovine trypanosomiasis in the Ghibe valley, southwest Ethiopia, the tsetse populations and their relationships to the prevalence of trypanosome infections in cattle. The tsetse challenge to cattle at two sites in the area was estimated as the product of tsetse relati...
