Resumo: The objective of this work was to evaluate the resistance of advanced semi-erect cowpea (Vigna unguiculata) lines, by means of a screening assay for resistance and the elaboration of fertility-life tables of Aphis craccivora (Hemiptera: Aphididae). The experiments were carried out in a screenhouse. For the resistance trial, 15 advanced cowpea lines were used, as well as two standard genotypes for resistance and two for susceptibility, which were arranged in six blocks. After resistance was determined, two lines with the highest and lowest resistance were selected for the development of the fertility-life tables which were used to estimate demographic parameters. The MNCO4-762F-03 and MNCO4-762F-09 cowpea lines were classified as resistant, for which cowpea aphids showed the lowest values (in parentheses, respectively) for: net reproductive rate (RO = 3.0 and 2.5), intrinsic rate of increase (rm = 0.16 and 0.15), and finite rate of increase (λ = 1.18 and 1.16). The highest values were obtained for the 'Vita-7', MNCO4-795F-168, and 'BRS Tumucumaque' genotypes. The MNCO4-762F-03 and MNCO4-762F-09 lines show antibiosis-type resistance, which directly affects the reproductive potential of the cowpea aphid population.

Os experimentos foram realizados em telado. Para o ensaio de resistência, utilizaram-se 15 linhagens avançadas de feijão-caupi, assim como dois genótipos-padrão de resistência e dois de susceptibilidade, os quais foram distribuídos em seis blocos. Após ter-se determinado a resistência, selecionaram-se as duas linhagens com o maior e o menor grau de resistência, para compor o ensaio destinado à elaboração de tabelas de vida de fertilidade que foram utilizadas para estimar os parâmetros demográficos. As linhagens de feijão-caupi MNCO4-762F-03 e MNCO4-762F-09 foram classificadas como resistentes, nas quais, o pulgão-preto apresentou os menores valores (nos parênteses, respectivamente) de: taxa líquida de reprodução (RO = 3,0 e 2,5); taxa intrínseca de crescimento (rm = 0,16 e 0,15); e razão finita de crescimento (λ = 1,18 e 1,16). Os maiores valores foram obtidos nos genótipos 'Vita-7', MNCO4-795F-168 e 'BRS Tumucumaque'. As linhagens MNCO4-762F-03 e MNCO4-762F-09 apresentam resistência do tipo antibiose, o que afeta diretamente o potencial reprodutivo da população de pulgão-preto.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraConselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Silva, Leandro Carvalho daNere, Daniel RodriguesBleicher, ErvinoBarbosa, Antônio Vinícius CorreaTavares, Eraldo José Madureira2018-10-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/25875Pesquisa Agropecuaria Brasileira; v.53, n.8, ago. 2018; 900-908Pesquisa Agropecuária Brasileira; v.53, n.8, ago. 2018; 900-9081678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/25875/14268https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/25875/17569Direitos autorais 2018 Pesquisa Agropecuária Brasileira; programa Agronomia: Fitotecnia da Universidade Federal do Ceará (UFC)info:eu-repo/semantics/openAccess2018-10-19T20:43:08Zoai:ojs.seer.sct.embrapa.br:article/25875Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2018-10-19T20:43:08Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
