Abstract

Within the Bemisia tabaci group of cryptic whitefly species, many are damaging agricultural pests and plant-virus vectors, conferring upon this group the status of one of the world’s top 100 most invasive and damaging ‘species’ that affect farmers’ income and livelihoods. Studies on the microbiome of whitefly life stages are scarce, although their composition and diversity greatly influence whitefly fitness and development. We used high-throughput sequencing to understand microbiome diversity in different developmental stages of the B. tabaci sub-Saharan Africa 1 (SSA1-SG1) species of the whitefly from Uganda. Endosymbionts (Portiera, Arsenophonus, Wolbachia and Hemipteriphilus were detected but excluded from the further statistical analysis as they were not influenced by life stage using( Permutational Multivariate Analysis of Variance Using Distance Matrices, (ADONIS, p= 0.925 and Bray, p = 0.903). Our results showed significant differences in the microbiome composition in different life stages of SSA1-SG1. The diversity was significantly higher in eggs (Shannon, p = 0.024; Simpson, p = 0.047) than that in nymphs and pupae, while the number of microbial species observed by the amplicon sequence variant (ASV) was not significant (n(ASV), p = 0.094). At the phylum and genus levels, the dominant constituents in the microbiome changed significantly at different developmental stages, with Halomonas being an egg-associated genus while Bacillus and Caldalkalibacillus were common in all life stages. These findings provide the first description of differing microbiome diversity in the life stage of whiteflies, suggesting their putative role in whitefly development.
