Potential gene targets for managing cassava whitefly, a viral diseases vector threatening food security

Whiteflies, particularly the African cassava whitefly (Bemisia tabaci, SSA1-SG1), pose a significant threat to agricultural productivity in sub-Saharan Africa by transmitting viruses that cause cassava brown streak disease and cassava mosaic virus disease. In a new study published in PeerJ, Dr. Tadeo Kaweesi and his team at the National Agricultural Research Organization identify potential gene targets that could revolutionize the management of this devastating pest and prove vital for food security in the region.

So far in the UK it doesn't seem especially prone to pests/diseases, so doesn't need much in the way of spray treatments. I don't know whether it's a host of the honeysuckle #whitefly Aleyrodes lonicerae (which is one of my favourite whitefly species).

#Whitefly-transmitted #viruses of #cucurbits in the southern United States, including #begomoviruses, #criniviruses, and #ipomoviruses - Review of their biology, epidemiology, and management options like resistance and cultural practices - Article in the journal Viruses by Ragunathan Devendran and others - https://doi.org/10.3390/v15112278
Whitefly-Transmitted Viruses of Cucurbits in the Southern United States

Cucurbits are economically important crops that are widely cultivated in many parts of the world, including the southern US. In recent years, higher temperatures have favored the rapid build-up of whiteflies in the fall-grown cucurbits in this region. As a result, whitefly-transmitted viruses (WTVs) have severely impacted the marketable yield of cucurbits. In this review, we discuss three major groups of WTVs negatively impacting cucurbit cultivation in the southern US, including begomoviruses, criniviruses, and ipomoviruses. Here, we discuss the available information on the biology, epidemiology and advances made toward detecting and managing these viruses, including sources of resistance and cultural practices.

RT @virtigation: #Bacterial #symbionts & #endosymbionts could serve as a novel #whitefly control method. A new study by our partner @LIST_Luxembourg has found that plant-mediated rifampicin treatment of #Bemisiatabaci whitefly disrupts, but does not eliminate endosymbionts https://www.nature.com/articles/s41598-022-24788-0#article-info
