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...

The subhumid and semi-arid zones of West Africa are one of the subregions reputed to hold Africa's greatest potential for expansion of animal agriculture. Within this region livestock are affected by tsetse-transmitted trypanosomosis-a disease that severely constrains productivity, thus hampering...

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...

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...
