“…Tajebe et al (2015), however, found Arsenophonus as a single infection or coinfected with Cardinium in Tanzania, indicating the huge differences in the results obtained between the studies. In Nigeria, Arsenophonus, Rickettsia, Wolbachia, Cardinium and Hamiltonella were detected in B. tabaci SSA1 (Akintola et al, 2020). Arsenophonus, Wolbachia, Rickettsia, and Cardinium have been detected in B. tabaci SSA1 from Uganda and Tanzania on cassava (Sseruwagi et al, 2018).…”

Sap-sucking insects, including whiteflies, are amongst the most devastating and widely distributed organisms on the planet. They are often highly invasive and endosymbiont communities within these insects help them adapt to new or changing environments. Bemisia tabaci (Gennadius; Hemiptera: Aleyrodidae) whitefly species are vectors of more than 500 known plant-viruses and harbour highly diverse endosymbionts communities. To date, however, whitefly–endosymbiont interactions, community structure and their spatio-temporal changes are still poorly understood. In this study, we investigated the spatio-temporal changes in the composition and diversity of bacterial endosymbionts in the agricultural crop pest whitefly species, Bemisia tabaci sub-Saharan Africa 1-subgroup 1 and 2 (SSA1-SG1 and SSA1-SG2). 16S rRNA amplicon sequencing analysis was carried out to characterise endosymbiont compositionsin field-collected SSA1 (SSA1-SG1 and SSA1-SG2) populations infesting cassava in Uganda in 1997 and 2017. We detected Portiera, Arsenophonus, Wolbachia, Hamiltonella and Hemipteriphilus, with Arsenophonus and Wolbachia infections being predominant. Hemipteriphilus and Hamiltonella frequencies were very low and were detected in seven and two samples, respectively. Bacterial diversity based on three independent parameters including Simpson index, number of haplotypes and Bray–Curtis dissimilarity matrix was significantly higher in 1997 than in 2017. This period also coincided with the advent of super-abundant cassava-whitefly populations on cassava crops in Uganda. We discuss how endosymbionts may influence the biology and behaviour of whiteflies leading to population explosions.

“…Whiteflies are known to be infected with a primary endosymbiotic bacteria Portiera, and seven secondary endosymbionts (Sendosymbionts): (i) Cardinium, (ii) Arsenophonus, (iii) Hamiltonella, (iv) Rickettsia, (v) Wolbachia, (vi) Fritschea, and (vii) Hemipteriphilus aquaticus (Bing et al, 2012;Chiel et al, 2007;Everett et al, 2005;Gottlieb et al, 2008). Of these, Arsenophonus, Cardinium, Hamiltonella, Rickettsia, and Wolbachia were prevalent in SSA1 whiteflies with Arsenophonus infection reaching up to 46.5% in Nigeria with three strains found (Akintola et al, 2020), while in East Africa, Arsenophonus infection reached 64%.…”
