Figure 1 Location of Captisol sampling sites indicating the presence of the genetic groups of Bemisia tabaci (Q2, Q3, AnSL, ASL, Ms), Bemisia afer and Trialeurodes vaporariorum. Samples were collected in mainland France (FR), Spain (ES), Israel (IL), Burkina Faso (BF), Togo (TG), Benin (BJ), Tanzania (TZ), Seychelles (SC), Comoros Grande Comore (KM), Mayotte (YT), Madagascar (MG), Mauritius (MU) and Reunion (RE). DNA extraction and PCR amplification Arsenophonus detection Interleukin-3 receptor and identification of B. tabaci genetic groups Insects were sexed and DNA was extracted as previously described by Delatte et al. [49]. All samples were screened for Arsenophonus infection using the specific primers Ars-23S1/Ars-23S2 targeting the 23S RNA gene [50] (Table 2). To check for extracted DNA quality, all samples were also tested for the presence of the primary symbiont
P. aleyrodidarum using specific primers for the 16S rRNA genes described by Zchori-Fein and Brown [23]. When positive signals were recorded in both PCRs, insects were used in the analysis. B. tabaci genetic groups were identified by PCR-RFLP (random fragment length polymorphism) test based on the mitochondrial marker COI (Cytochrome Oxidase 1) gene as described by Gnankine et al. [35] for Q, ASL and AnSL individuals. A set of 10 microsatellite markers was used to identify Ms according to Delatte et al. [42]. Moreover, a portion of the COI gene was sequenced for five individuals from each of the different B. tabaci genetic groups, using the protocol described by Thierry et al. [37] and Gnankine et al.
