Atratividade de genótipos de feijão-caupi para oviposição de Bemisia tabaci biótipo B
[Attractiveness of cowpea genotypes for Bemisia tabaci B-biotype oviposition]
Pesquisa Agropecuária Brasileira 47 (11), 1563-1571
Abstract: The objective of this work was to evaluate the attractiveness of cowpea genotypes for Bemisia tabaci B-biotype oviposition, and to identify possible sources of resistance. Fifty-one genotypes were evaluated using free-choice tests. The genotypes were randomly divided into two groups, using the genotype Canapu as a susceptible control. The fourteen most promising genotypes (seven from each group) were selected for complementary testing (with or without choice). In the free-choice test, BRS-Urubuquara, TVU-36, TE93-244-23 F-1, BR 17-Gurgueia, BRS-Marataoã, MNC99-541 F-21, and TE97-304 G-4 were less attractive to the whitefly. The genotypes TE93-244-23 F-1 and TVU-36 stud out and showed non-preference resistance for ovoposition. In the no-choice test, the genotype TVU-36 showed resistance by this same mechanism.
