Molecular Diversity and Distribution of Whiteflies (Bemisia tabaci) in Cassava Fields Across South West and North Central, Nigeria

Insects
Whitefly Bemisia tabaci (Gennadium, Hemiptera) causes severe damage to cassava plants through excessive feeding on leaves and transmitting viruses, such as African cassava mosaic virus (ACMV), East African cassava mosaic virus (EACMV), and ipomoviruses ...

CASSAVA MOSAIC DISEASE: INCIDENCE AND YIELD PERFORMANCE OF CASSAVA CULTIVARS IN ZAMBIA

Journal of Plant Pathology, 2017
Cassava is the main food crop for an estimated 30% of the population in Zambia where yields of 5.8 t/ha are some of the lowest of any major cassava-producing country. A study was conducted to characterize yield responses of Zambian cassava genotypes to cassava mosaic disease (CMD), as well as the relative susceptibilities to the causal viruses.

Sensitivity analysis and optimal control for the dynamic mathematical model of cassava mosaic disease

AIP Advances
Cassava mosaic disease (CMD) is found in many countries around the world. This disease is caused by a mosaic virus carried by whitefly. It hurts the growth and yield of cassava, which in turn causes damage to farmers who grow cassava.

Phylogenetic Relationships among Whiteflies in the Bemisia tabaci (Gennadius) Species Complex from Major Cassava Growing Areas in Kenya

Insects, 2017
Whiteflies, Bemisia tabaci (Gennadius) are major insect pests that affect many crops such as cassava, tomato, beans, cotton, cucurbits, potato, sweet potato, and ornamental crops. Bemisia tabaci transmits viral diseases, namely cassava mosaic and cassava

Cassava mosaic disease in Madagascar: complex epidemiology and evolutionary dynamics of cassava mosaic geminiviruses

, 2016
BACKGROUND and OBJECTIVES Cassava is the staple food for hundreds of millions of people in Africa but its cultivation is seriously constrained by cassava mosaic disease (CMD) in Madagascar and in Africa in general. We have undertaken (1) to identify the cassava mosaic geminiviruses (CMGs) involved in CMD in Madagascar and their epidemiological ...

Engineering Cassava Mosaic Disease (CMD) Resistance in a Ghanaian Cassava Cultivar

, 2018
Cassava is an important staple crop for an estimated 800 million people worldwide. Cassava production in Africa is constrained by cassava mosaic disease (CMD) and cassava brown streak disease (CBSD). Both viral diseases cause annual yield losses estimated around $2.1 billion.
