L. B.  aResistance Sources and Antixenotic Factors in Brazilian Bean Genotypes Against Bemisia tabaci.h[electronic resource]  c2021  aBemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) Middle East Asia Minor 1 is one of the most important pests of the common bean, due to its potential of causing direct and indirect damage. This study aimed to evaluate 78 bean genotypes to verify the occurrence of resistance of antixenosis type against B. tabaci. Initially, multiple-choice trials were performed to evaluate the oviposition preference and nymphs? establishment at 3 and 15 days after infestation. Subsequently, 21 bean genotypes were selected, and a no-choice test was conducted. Colorimetric analyses were performed to establish correlations between leaf color and insect establishment. In multiple-choice trial, the genotypes BRS Ametista, BRS Estilo, BRS Esplendor, SCS 204 Predileto, BRS Not??vel, IPR Eldorado, CHIB 06, IPR Quero-Quero, Iapar 81, CHIP 338, IPR Gar??a, Arcelina 4, SCS 202 Guar??, IAC Esperan??a, H96102-1-1-1-52, CHIP 348, Carioca Comum, CHIP 300, IAC Carioca Et??, IAC Ybat??, and Tybat?? were the least used for oviposition and nymph establishment, demonstrating antixenosis or antibiosis. In the no-choice trial, most genotypes were less attractive to whitefly, and the genotypes CHIB 06, IPR Gar??a, CHIP 300, and IAC Esperan??a had less oviposition. The most attractive genotypes presented high luminosity and more intense green and yellow colors, indicating positive correlation. Therefore, the genotypes BRS Ametista, SCS 204 Predileto, BRS Estilo, IPR Eldorado, SCS-202 Guar??, Carioca Comum, Arcelina 4, CHIP 348, and IAC Esperan??a showed the highest resistance stability in the no-choice trial, and they are promising sources of antixenotic factors for use in breeding programs to obtain whitefly-resistant common bean lines.  aantixenosis  acolorimetry  ahost selection  aPhaseolus vulgaris L  atrichomes  aWhitefly1 aBALDIN, L.
