S14.239 aTomato genotypes of different species were evaluated for colonization of Bemisia tabaci (Gennadius) biotype B under greenhouse conditions. The experiment was conducted in a randomized block design, with a split-pot scheme and three rep-licates. Plant infestation was done at 40-45 days after seedling transplanting by introducing highly whitefly-infested soybean plants. The variables evaluated were nymph number on the adaxial and abaxial surfaces of the leaflets, during five weeks. Each observation was composed by the mean numbers obtained for three leaflets. There were no significant differences among genotypes for the first three evaluations regarding to the presence of nymphs. LA1739 and PI134418 were the only genotypes not infested by nymphs on the abaxial surface of the leaf-lets. On the abaxial surface, the least infested genotypes were LA0462, LA0716, LA1740, PI134417 and PI134418, P25 and WIR2920 were the most infested genotypes. aTomate1 aVENDRAMIM, J. D.1 aLOURENÇÃO, A.
