Abstract: The objective of this work was to develop sequence-characterized amplified region (Scar) markers to identify the B, Q, and native Brazilian biotypes of the sweet potato whitefly [Bemisia tabaci (Hemiptera: Aleyrodidae)]. Random amplified polymorphic DNA (RAPD) amplification products, exclusive to the B and Brazilian biotypes, were selected after the analysis of 12,000 samples, in order to design a specific Scar primer set. The BT-B1 and BT-B3 Scar markers, used to detect the B biotype, produced PCR fragments of 850 and 582 bp, respectively. The BT-BR1 Scar marker, used to identify the Brazilian biotype, produced a PCR fragment of 700 bp. The Scar markers were tested against the Q biotype, and a flowchart was proposed to indicate the decision...
