Investigations were conducted at Serere Agricultural Research Station (eastern Uganda) to identify and promote resistance of cassava to Mononychellus tanajoa, the most destructive arthropod pest of cassava in the country. Six cassava families that were imported from the International Institute of Tropical Agriculture, Nigeria, as seeds and included in the breeding program exhibited different degrees of hairiness of leaf surface. When they were subjected to severe mite attack during the dry season, their resistance correlated with the number of hairs on the leaves. This information helped in selecting cassava varieties with high mite resistance.
