Wild species of the Manihot genus offer a potential source of genes with resistance to the major arthropod pests of cultivated cassava (Manihot esculenta Crantz). Recent research at the International Center of Tropical Agriculture (CIAT) in Cali, Colombia has resulted in moderate to high levels of resistance to the cassava green mite (Mononychelus tanajoa), the cassava mealy bug (Phenacoccus herreni) and the cassava whitefly (Aleurotrachelus socialis) being detected in Manihot flabellifolic and in interspecific progeny from crosses with M. esculenta. It is planned that commercial cassava varieties can be developed using novel molecular tools for gene mapping (QTL) and back crossing populations (ABC-QTL).
