Abstract

Insect vectors and their associated viruses hinder agriculture production within . · smallholder agro-ecosystems of East Africa. In this study, vector metatranscriptomics ·· and virus metagenomic analysis identified seven viruses that were under slow evolutionary rate and two whitefly vectors Trialeurodes vaporariorium and Bemisia. tabaci. However there was no overlap of viruses identified within B. /abaci and host plants. It is therefore probable that whiteflies are not the predominant vectors of legumes in the western highlands of Kenya. This study, therefore, fills a critical knowledge gap, particularly in understanding the association between viruses, their evolution, and the probable role of whiteflies.
