Abstract

A major cause of yield loss in cassava, Manihot esculenta Crantz in tropical Africa is African cassava mosaic virus, transmitted by the whitefly, Bemisia tabaci (Gennadius). Investigations into the epidemiology of the disease and the ecology of the insect vector at the Kenya coast demonstrated that the serious loss of yield caused by the virus could be greatly reduced if simple changes in husbandry practices were adopted. The regular rogueing of infected plants greatly reduced the incidence of African cassava mosaic virus.

Résumé

Les pertes de rendement de la production du manioc, Manihot esculenta Crantz en Afrique tropicale sont dues au African cassava mosaic virus (CMV), transmit par la mouche Bemisia tabaci (Gennadius). Au Kenya, sur la côte, des études épidemiologiques de la maladie et de l'écologie de l'insecte vecteur ont montré qu'il était possible de réduire les pertes graves causées par le virus en modifiant légèrement les pratiques agricoles. L'élimination régulière des plantes infectées diminuera fortement l'effet du CMV.
