Resistance to Cassava Whitefly (Bemisia tabaci) among Eastern and Southern African Elite Cassava Genotypes [PDF]

Insects
Cassava whitefly, Bemisia tabaci, directly damages cassava leaves by feeding on phloem, causing chlorosis and abscission, leading to a yield loss of up to 50%. The pest also causes indirect damage through sooty mold formation.

Cassava disease detection using a lightweight modified soft attention network. [PDF]

Pest Manag Sci
The main framework of the proposed CDDNet approach. Abstract BACKGROUND Cassava is a high‐carbohydrate crop that is at risk of viral infections. The production rate and quality of cassava crops are affected by several diseases. However, the manual identification of diseases is challenging and requires considerable time because of the lack of field ...

Farmer and Field Survey in Cassava-Growing Districts of Rwanda Reveals Key Factors Associated With Cassava Brown Streak Disease Incidence and Cassava Productivity

Frontiers in Sustainable Food Systems, 2021
Cassava (Manihot esculenta Crantz) is a vital crop in Rwanda where it ranks as the third most consumed staple. However, cassava productivity remains below its yield potential due to several constraints, including important viral diseases, such as cassava

Survey of cassava brown streak disease and association of factors influencing its epidemics in smallholder cassava cropping systems of coastal Kenya

Frontiers in Sustainable Food Systems, 2023
Cassava productivity is threatened by viral diseases which have become the main phytosanitary problems in cassava farmers. Cassava brown streak disease (CBSD) is a devastating viral disease caused by Cassava brown streak virus (CBSV) and Ugandan cassava ...

Epidemiological Analysis of Cassava Mosaic and Brown Streak Diseases, and Bemisia tabaci in the Comoros Islands

Viruses, 2022
A comprehensive assessment of cassava brown streak disease (CBSD) and cassava mosaic disease (CMD) was carried out in Comoros where cassava yield (5.7 t/ha) is significantly below the African average (8.6 t/ha) largely due to virus diseases. Observations

Exploiting the combination of natural and genetically engineered resistance to cassava mosaic and cassava brown streak viruses impacting cassava production in Africa. [PDF]

PLoS ONE, 2012
Cassava brown streak disease (CBSD) and cassava mosaic disease (CMD) are currently two major viral diseases that severely reduce cassava production in large areas of Sub-Saharan Africa. Natural resistance has so far only been reported for CMD in cassava.

Incidence, severity and distribution of Cassava brown streak disease in northeastern Democratic Republic of Congo

Cogent Food & Agriculture, 2020
Cassava fields were prospected from two provinces of the Democratic Republic of Congo (Ituri and Haut Uélé) to evaluate the ampleness of Cassava brown streak disease (CBSD) infection.

High-Throughput Virus Screening in Crosses of South American and African Cassava Germplasm Reveals Broad-Spectrum Resistance against Viruses Causing Cassava Brown Streak Disease and Cassava Mosaic Virus Disease

Agronomy, 2022
Screening cassava lines for resistance against viruses causing cassava brown streak disease (CBSD) is cumbersome because of the unpredictable and erratic virus infections in the slow plant infection processes that are frequently not associated with ...

Nymphstar: An accurate high‐throughput quantitative method for whitefly (Aleurotrachelus socialis Bondar) resistance phenotyping in cassava

The Plant Phenome Journal, Volume 6, Issue 1, December 2023., 2023
Abstract Whitefly (Aleurotrachelus socialis Bondar) is a major pest causing significant economic losses in cassava production systems in North South America. It diminishes cassava's photosynthesis by colonizing leaves, directly feeding on phloem sap, or excreting substances that foster sooty mold growth, reducing the photosynthetic area.
