The objective of this work was to evaluate bean genotypes for resistance to soybean looper (Chrysodeixis includens). Initially, free-choice tests were carried out with 59 genotypes, divided into three groups according to leaf color intensity (dark green, light green, and medium green), in order to evaluate oviposition preference. Subsequently, 12 genotypes with high potential for resistance were selected, as well as two susceptible commercial standards. With these genotypes, new tests were performed for oviposition in a greenhouse, besides tests for attractiveness and consumption under laboratory conditions (26±2ºC, 65±10% RH, and 14 h light: 10 h dark photophase). In the no-choice test with adults, in the greenhouse, the 'IAC Jabola', Arcelina 1, 'IAC... |

O objetivo deste trabalho foi avaliar a atratividade de genótipos de feijão-caupi para oviposição de Bemisia tabaci biótipo B e identificar possíveis fontes de resistência à mosca-branca. Foram avaliados 51 genótipos, com uso de testes de chance de escolha. Os genótipos foram divididos aleatoriamente em dois grupos, tendo-se utilizado o genótipo Canapu como testemunha sucetível. Os 14 genótipos mais promissores (sete de cada grupo) foram selecionados para a realização de ensaios complementares (com ou sem chance de escolha). No teste com chance de escolha, os genótipos BRS-Urubuquara, TVU-36, TE93-244-23 F-1, BR 17-Gurgueia, BRS-Marataoã, MNC99-541 F-21 e TE97-304 G-4 foram menos atrativos à mosca-branca. Os genótipos TE93-244-23 F-1 e TVU-36 apresentaram... |

The objective of this work was to characterize the resistance of 50 cowpea (Vigna unguiculata) genotypes to Callosobruchus maculatus. A completely randomized design with five replicates per treatment (genotype) was used. No-choice tests were performed using the 50 cowpea genotypes to evaluate the preference for oviposition and the development of the weevil. The genotypes IT85 F-2687, MN05-841 B-49, MNC99-508-1, MNC99-510-8, TVu 1593, Canapuzinho-1-2, and Sanzi Sambili show non-preference-type resistance (oviposition and feeding). IT81 D-1045 Ereto and IT81 D-1045 Enramador exhibit antibiosis against C. maculatus and descend from resistant genitors, which grants them potential to be used in future crossings to obtain cowpea varieties with higher levels of... |
