Displays two 2% agarose gels showing the restriction fragment length polymorphism profiles obtained by digesting the COI with AluI (A) and AseI + TaqI (B) enzyme from Lecanoideus floccissimus (lane 1), Aleurotrachelus socialis (lane 2), Bemisia tabaci (Sample 1, lane 3), B. tabaci (Sample 2, lane 4), Trialeurodes vaporiariorum (lane 5), Aleurodicus dispersus (lane 6), Aleurothrixus floccosus (lane 7), Aleurotrachelus trachoides (lane 8), Trialeurodes variabilis (lane 9), Aleuronudus melzeri (lane 10). Molecular size markers are shown on the right and left side of the figure. Number filled in black corresponds to fragments size expected based on available sequence information and those in red to fragments expected by sequence variation due to intraspecies variation detected by RFLP-PCR of the COI amplicon.
