Diagnostic surveys were conducted in 2002 and 2003 in order to provide a comprehensive and detailed assessment of the status of cassava mosaic disease (CMD) in the Republic of Congo (ROC) and to determine if the disease was spreading. In 2002, 105 farmers’ fields were assessed in the four major c...

Parasitism rates of Bemisia tabaci(Gennadius) and searching and oviposition behaviours of its parasitoid Eretmocerus mundus Mercet were compared on two cassava varieties: a glabrous variety, Nase 4 and a hirsute variety, MM970245 withc.88 leaf hairscm2. Parasitism was assessed after potted plants...

Cassava diseases are major production constraints wherever the crop is grown. Although diseases will continue to pose a challenge to cassava producers in the immediate future, tremendous progress is being made in developing control tactics. These range from biotechnological approaches for enhanci...

Bemisia tabaci (Gennadius) is the vector of cassava mosaic geminiviruses (CMGs) and cassava brown streak viruses (CBSVs) in Africa, which cause devastating yield losses. As a prerequisite to developing biological control methods and enhancing knowledge of the fauna of whitefly parasitoids in sub-...

Cassava mosaic disease (CMD) is the most important constraint to cassava (Manihot esculenta) production in Africa. Since the 1990s, the importance of the disease has been greatly increased by the spread through East and Central Africa of a pandemic of unusually severe CMD (Legg, 1999), associated...

Here, we report a method to clean cassava plants from viral infections that cause cassava mosaic and brown streak diseases in Africa. Infected plants of resistant or tolerant varieties from Malawi, Mozambique, Kenya, Tanzania and Uganda were cleaned in the UK using a combination of tissue culture...

Cassava mosaic begomoviruses (CMBs) cause cassava mosaic disease (CMD) across Africa and the Indian subcontinent. Like all members of the geminivirus family, CMBs have small, circular single-stranded DNA genomes. We report here the discovery of two novel DNA sequences, designated SEGS-1 and SEGS-...
