A survey in Senegal and Guinea Conakry established the presence and incidence of cassava mosaic virus disease (CMD) in both countries. CMD occurred in all the fields surveyed, although its incidence was higher in Senegal (83%) than in Guinea (64%). Populations of the whitefly vector, Bemisia taba...

Viruses associated with cassava mosaic disease in Senegal and Guinea Conakry
Several begomovirus species and strains causing cassava mosaic disease (CMD) have been reported from cassava in Africa. A diagnostic survey was made in the four agroecological zones of Guinea to determine the status of CMD and cassava begomoviruses and to ascertain if the virulent Ugandan variant...

Distribution and current status of cassava mosaic disease and begomoviruses in Guinea
A survey was carried out of 86 cassava fields in the lowland savanna; humid forest, mid-altitude savanna, and lowland humid savanna agroecological zones of Guinea. Each field was assessed for the incidence and severity of cassava bacterial blight (CBB), cassava anthracnose disease (CAD), Cercospo...

Cross sectional surveys (2002-2004) achieved in 89 villages, carried on 5474 cattle and 1908 tse tse flies (G. palpalis: 53%; G. tachinoides: 45% and G. morsitans: 2%) have been captured. Following these investigations, several suspected villages have been chosen for longitudinal surveys in order...

Trypanotolerant livestock in West and Central Africa. Volume 2. Country studies - Chapter 4. Guinea
This study was carried out in Northeast Guinea to investigate farmer knowledge, attitude and practice (KAP) relating to trypanosomosis management; elucidate factors that influence animal-health-seeking behaviour and outcome; and investigate factors associated with high risk for chemo-resistance. ...

Managing trypanosomosis: knowledge, attitude and practice in Upper Guinea
To investigate the importance of trypanosomosis, resistance to trypanocidal drugs and the potential impact of integrated control measures on these factors, a 3-phase study was initiated. The first phase was a cross-sectional study in which tsetse apparent density, cattle trypanosome prevalence, t...
