Resistência de genótipos de abobrinha a Bemisia tabaci (Genn.) biótipo B (Hemiptera: Aleyrodidae)
[Resistance of squash genotypes to Bemisia tabaci (Genn.) biotype B (Hemiptera: Aleyrodidae)]
Neotropical Entomology 38 (4), 526-530
Abstract: Field assays were performed to evaluate the attractiveness and the non-preference of whitefly Bemisia tabaci (Genn.) biotype B for oviposition on squash genotypes (Cucurbita pepo) and to observe the susceptibility of genotypes (Novita, Sandy, Caserta Cac Melhorada, Novita Plus, Samira, Bianca, AF-2858 and Caserta TS) to silverleaf symptoms. The Sandy genotype was the least attractive to whitefly, while Novita Plus, AF-2858 and Samira were the most attractive. The Caserta Cac Melhorada genotype was the least preferred for oviposition. The Sandy and AF-2858 genotypes were the most productive, with the highest mean of fruits produced. The lowest silverleaf symptoms index was observed for the Sandy and Caserta Cac Melhorada genotypes.
