- Cassava (Manihot esculenta Crantz) plays an important role in ensuring food security of the population in Côte d'Ivoire. However, its production is seriously threatened by the virus disease of cassava. The objective of this study is to evaluate the effect of viruses on the yield of cassava. For this study, six varieties of cassava, two improved and four local were used in two localities of the Côte d'Ivoire (Adzope in the south-east and Yamoussoukro in the Center). Parameters related to the viral disease which are the incidence and severity of symptoms were evaluated. In this study 4 types of virus disease symptoms were observed. It is of embossing; shoestring, mosaic and chlorosis. The study carried out showed that the incidence of the symptoms of virus diseases was higher in Adzope (60.12 %) than in Yamoussoukro (40.45 %). The viral disease symptoms were more severe on the local varieties than on those improved. Similarly, the results obtained showed a very significant difference between the yields of plants not showing symptoms of viruses and virus-infected ones. The performance of the not virus infected plants was higher (22.02 t/ha) compared to those of plants showing symptoms of virus diseases (18.74 t/ha). The yield loss due to viruses of cassava rose to 3.5 t/ha on average is 15. The incidence and severity of symptoms were higher on local varieties in the locality of Adzope. The study shows that yields were higher for plants exhibiting no symptoms of viral diseases than those with symptoms of viral diseases
