Resumo: | The Diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), is one of the main plague-insect specie of Brassicaceae plants in Brazil and all over the world. The resistant genotypes use to its control is a promising alternative. This work aimed evaluates the eggs distribution along the plant, the adults' density per plant, and determine the cauliflower genotypes effect in the P. xylostella oviposition. The experiment was carried out at FCAV/UNESP-Jaboticabal Campus Phytossanity Department (Departamento de Fitossanidade). It was evaluated the eggs distribution, the P. xylostella adults density effect using Sharon hybrid, and tests with or without choose choice to determine the P. xylostella nonpreference in the Teresopolis Gigante, Verona, Barcelona, Sharon, Silver Streak, and Piracicaba Precoce genotypes. It is possible conclude that P. xylostella has higher willingness to oviposits in the stem than in the basal leaves. The three couple density of P. xylostella per plant is the best to discriminate cauliflower genotypes regarding the resistance grade to nonpreference choose choice to oviposition. During the P. xylostella oviposition preference tests with choose choice, the genotypes Sharon, Piracicaba Precoce, Barcelona, Verona e Teresopolis Gigante are less desirable to oviposition; while during the no choose choice tests the genotypes did not differ among them. |

(Lepidoptera: Plutellidae), é uma das principais espécies de inseto-praga de plantas da família Brassicaceae no Brasil e no mundo. A utilização de genótipos resistentes para o seu controle é uma alternativa promissora. O objetivo do presente trabalho foi avaliar a distribuição dos ovos na planta, a densidade de adultos por planta e determinar o efeito de genótipos de couve-flor na oviposição de P. xylostella. O experimento foi desenvolvido na área experimental do Departamento de Fitossanidade da FCAV/UNESP - Campus de Jaboticabal, SP. Foram utilizados os genótipos Teresópolis Gigante, Verona, Barcelona, Sharon, Silver Streak e Piracicaba Precoce. A distribuição de ovos e o efeito da densidade de adultos de P. xylostella foram avaliados somente com a utilização do genótipo Sharon. Enquanto nos testes para determinar o efeito de genótipos de couve-flor na oviposição da P. xylostella foram avaliados além do genótipo Sharon o Teresópolis Gigante, Verona, Barcelona, Sharon, Silver Streak e Piracicaba Precoce. Concluiu-se que a P. xylostella tem maior preferência para ovipositar no caule do que nas folhas basais da planta. A densidade de três casais de adultos de P. xylostella por planta é a melhor para discriminar genótipos de couve-flor quanto aos graus de resistência para não-preferência para oviposição. Nos testes de preferência para oviposição de P. xylostella com chance de escolha os genótipos Sharon, Piracicaba Precoce, Barcelona, Verona e Teresópolis Gigante são os menos preferidos para oviposição, enquanto nos testes sem chance de escolha os genótipos não diferiram entre si.UNESP, FCAV, Dept Fitossanidade, BR-14884900 Jaboticabal, SP, BrazilUEMG, Frutal, MG, BrazilUNESP, FCAV, Dept Fitossanidade, BR-14849900 Jaboticabal, SP, BrazilUNESP, FCAV, Dept Fitossanidade, BR-14884900 Jaboticabal, SP, BrazilUNESP, FCAV, Dept Fitossanidade, BR-14849900 Jaboticabal, SP, BrazilUniv Fed Rural Semi-arido-ufersaUniversidade Estadual Paulista (Unesp)Universidade do Estado de Minas Gerais (UEMG)Boica Junior, Arlindo Leal [UNESP]Chagas Filho, Norton Rodriguesde Souza, Joseane Rodrigues [UNESP]2014-05-20T13:14:51Z2014-05-20T13:14:51Z2010-01-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article28-33http://periodicos.ufersa.edu.br/revistas/index.php/sistema/article/view/1346Revista Caatinga.
