Improvement of cattle productivity through rapid alleviation of African animal trypanosomosis by integrated disease management practices in the agropastoral zone of Yalé, Burkina Faso.

Investigations to identify the causes of high mortalities in cattle in the agropastoral zone (ZAP) of Yalé started in March 1993. African animal trypanosomosis (AAT) was found to be the major constraint, with incidence rates exceeding 30%, justifying a tsetse control programme, which started in March/ April 1994. The treatment of all cattle at bimonthly intervals with deltamethrin 1% pour on and the display of 1500 insecticide impregnated targets during the 6 months of the dry season each year helped to reduce the tsetse populations (Glossina tachinoides and G.

Trypanosome characterization by polymerase chain reaction in Glossina palpalis gambiensis and G.tachinoides from Burkina Faso.

Following the discovery of four cases of African human trypanosomiasis, an entomological survey was conducted along the Mouhoun river in southwest Burkina Faso to collect Glossina palpalis gambiensis and G.tachinoides. Among 226 flies dissected, 4.

Successful application of deltamethrin pour on to cattle in a campaign against tsetse flies (Glossina spp.) in the pastoral zone of Samorogouan, Burkina Faso.

1,500-2,000 head of cattle were treated with deltamethrin 1% Spot On in an area of high tsetse densities, notably of Glossina morsitans submorsitans. After four treatments at monthly intervals, the time between two treatments was increased to two months. 11 months after the commencement of the campaign the fly population had decreased from initially 54.

[Trypanosoma congolese in different species of horse flies (Diptera: Tabanidae) in Burkina Faso].

Four out of six Azawak zebu bulls raised in northern Burkina Faso were found to be infected with trypanosomes, including Trypanosoma congolense, six months after they had been transferred, uninfected, to the CIRDES experimental farm at Banankélédaga (Southwest Burkina Faso). Entomological surveys are carried out regularly in the area around this farm but, in one year, only 10 tsetse flies were captured, none of which showed infection in the midgut. However, a large number of tabanids were captured in the Glossina traps and dissection of some of them showed the presence of trypanosomes in their midgut.
