Endosymbionts are important components of arthropod biology. The whitefly Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) is a cryptic species complex composed of ≥ 28 putative species. In addition to the primary endosymbiont Portiera aleyrodidarum , six secondary endosymbionts (S‐endosymbionts), Hamiltonella , Rickettsia , Wolbachia , Cardinium , Arsenophonus and Fritschea , have been identified in B. tabaci thus far. Here, we tested five of the six S‐endosymbiont lineages (excluding Fritschea ) from 340 whitely individuals representing six putative species from China. Hamiltonella was detected only in the two exotic invaders, Middle East‐Asia Minor 1 (MEAM1) and Mediterranean (MED). Rickettsia was absent in Asia II 1 and MED, scarce in Asia II 3 (13%), but abundant in Asia II 7 (63.2%), China 1 (84.7%) and MEAM1 (100%). Wolbachia , Cardinium and Arsenophonus were absent in the invasive MEAM1 and MED but mostly abundant in the native putative species. Furthermore, phylogenetic analyses revealed that some S‐endosymbionts have several clades and different B. tabaci putative species can harbor different clades of a given S‐endosymbiont, demonstrating further the complexity of S‐endosymbionts in B. tabaci. All together, our results demonstrate the variation and diversity of S‐endosymbionts in different putative species of B. tabaci , especially between invasive and native whiteflies.
