JESUS, Flávio Gonçalves de et al. Infestation of Bemisia tabaci biotype B and Caliothrips phaseoli on bean genotypes. Bragantia [online]. 2010, vol.69, n.3, pp.637-648. ISSN 0006-8705.

The response of bean genotypes to infestation of Bemisia tabaci (Genn.) biotype B and Caliothrips phaseoli (Hood) in field conditions on the winter, rainy and dry seasons was evaluated. The experiment was arranged in a randomized Sub-divided (19x3x6) blocks design with 19 genotypes (IAC Tybatã, IAC Una, FT Nobre, Pérola, Gen 96A98-15-3-32-1, Gen 96A45-3-51-52-1, IAC Alvorada, IAC Diplomata, Gen 96A3-P1-1-1, LP 98-122, LP 02-130, LP 01-38, LP 9979, BRS-Pontal, BRS-Requinte, BRS-Triunfo, BRS-Grafite, CV-48 and Z-28) Three crops seasons of (winter, rainy and dry seasons) and six periods of evaluations were considered. The evaluations consisted on counting eggs and nymphs of B. tabaci biotype B and nymphs of C. phaseoli in 10 leaflets per plot. The genotypes IAC Una, Pérola, Gen 96A45-3-51-52-1, Gen 96A98-15-32-1, FT Nobre, IAC Tybatã, IAC Alvorada, LP 02-130, LP 01-38, LP 98-122, IAC Diplomata e Gen 96A3P1-1-1 were the least oviposited by B. tabaci biotype B, in rainy season. The least presence of C. phaesoli was observed on Gen 96A45-3-51-52-1, IAC Una, Gen 96A98-15-32-1, IAC Tybatã and FT Nobre. The highest occurrence of whitefly nymphs was observed during rainy season and beginning of the dry season, while the thrips preferred the winter season. The highest incidence of the population of B. tabaci biotype B and C. phaseoli, was found 46 to 60 DAE.
