Recent and current efforts at IITA to assess risks due to the various biotic stresses, arthropod pests and diseases, are presented for different cropping systems. In the case of cassava arthropod pests, the focus is on temperature-mediated interactions between the pest and its natural enemy which...

Cassava mosaic disease (CMD) seriously affects cassava yields in Africa. This study compared the spatial distribution of CMD using three independent surveys in Rwanda and Burundi. Geostatistical techniques were used to interpolate the pointbased surveys and predict the spatial distributions of di...

Although cassava shows resilience against a myriad of pests and diseases, including several of viral aetiology, two virus disease complexes, cassava brown streak disease and cassava mosaic disease (CMD), are the major yield-limiting biotic constraints to its production in sub-Sahara Africa. Subse...
