A countrywide survey on cassava constraints in D.R. Congo was initiated in 2002 and completed in 2004 with the aim of assessing the health status of cassava in various agro-ecological zones of the 11 provinces of the country. The survey permitted to update the list of diseases and pests that cont...

Bemisia tabaci threatens production of cassava in Africa through vectoring viruses that cause cassava mosaic disease (CMD) and cassava brown streak disease (CBSD). B. tabaci sampled from cassava in eight countries in Africa were genotyped using NextRAD sequencing, and their phylogeny and populati...


Wosula, Everlyne N.Chen, W.Fei, Z.Legg, J.P.[Unravelling the genetic diversity among cassava Bemisia tabaci whiteflies using NextRAD Sequencing]Unravelling the genetic diversity among cassava Bemisia tabaci whiteflies using NextRAD Sequencing

The sweetpotato whitefly, Bemisia tabaci (Gennadius) is the vector of the cassava mosaic geminiviruses (CMGs) that cause cassava mosaic disease (CMD). Synergistic interactions between B. tabaci and CMGs have been hypothesized as a cause of whitefly “super-abundance,” which has been a key factor b...


Boni, S.B.Rugumamu, C.P.Gerling, D.Nokoe, K.S.Legg, J.P.[Interactions Between Cassava Mosaic Geminiviruses and Their Vector, Bemisia tabaci (Hemiptera: Aleyrodidae)]Interactions Between Cassava Mosaic Geminiviruses and Their Vector, Bemisia tabaci (Hemiptera: Aleyrodidae)
Autor: Legg, J.P.

Cassava is an important crop in many parts of the tropics, but it plays a particularly vital role in sustaining food security in sub-Saharan Africa. Diseases are the greatest biotic constraint to cassava production worldwide. Although the diversity of cassava pathogens is greatest in Latin Americ...


Legg, J.P.[Cassava diseases: ecology and control]Cassava diseases: ecology and control

A survey was carried out of African cassava mosaic geminivirus and cassava brown streak virus diseases (ACMD and CBSD) in Tanzania. ACMD occurred throughout the country at low to moderate incidences in the fifteen different regions surveyed (1- 64%). The incidence was generally higher along the c...


Legg, J.P.Raya, M.[Survey of cassava virus diseases in Tanzania]Survey of cassava virus diseases in Tanzania

The greatest current threat to cassava in sub-Saharan Africa, is the continued expansion of plant virus pandemics being driven by super-abundant populations of the whitefly vector, Bemisia tabaci. To track the association of putatively genetically distinct populations of B. tabaci with pandemics ...

Cassava brown streak disease (CBSD), caused by cassava brown streak viruses, is recognized as one of the most important plant disease threats to African food security. This study describes the incidence and severity of the different symptom types caused by CBSD, derived from extensive surveys in ...
