Cassava Brown Streak Disease (CBSD) is a very serious disease in many cassava growing areas of the Eastern zone of Tanzania. It is mainly confined to the lower elevations, mainly along the coast yield losses of up to 74% occur as a result of CBSD infection in some part of the Eastern zone. In the...

Cassava mosaic disease (CMD), recognized in Africa for more than a century, is now known to be caused by a group of geminiviruses in the genus Begomovirus from the family Geminiviridae. All are transmitted in a persistent manner by the whitefly vector, Bemisia tabaci. Structurally, cassava mosaic...

Cowpea aphid (Aphis craccivora Koch) is a major pest of cowpea (Vigna unguiculata L. Walp.) particularly in the drier regions of the tropics. Although aphid resistant varieties had been developed, resistance has recently broken down. The present study seeks to identify new sources of resistance. ...

Cassava mosaic disease and cassava brown streak disease are caused by viruses transmitted by Bemisia tabaci and affect approximately half of all cassava plants in Africa, resulting in annual production losses of more than $US 1 billion. A historical and current bias towards virus rather than vect...
