Resumo: The objective of this work was to evaluate the response of eight commercial wheat cultivars (BRS 194, BRS 208, BRS Camboatá, BRS Guabiju, BRS Guamirim, BRS Louro, BRS Timbaúva e BRS Umbu) to the infestation of Rhopalosiphum padi (Hemiptera: Aphididae). The experiment was carried out at Embrapa Trigo, in greenhouse conditions. It was used the randomized block design, in a split-plot array, with eight treatments and six replicates. The plots received treatments with or without infestation with aphids, and the split-plots were composed by the cultivars. The infestation with aphids (20 wingless adults per plant) was done 12 days after plant emergency, in the beginning of tillering, and was kept for 15 days. The cultivars responded differently to the infestation with aphids. BRS Timbaúva cultivar is more resistant, and BRS Umbu and BRS Guabiju cultivars are more susceptible to R. padi, concerning plant growth and plant yield.

O experimento foi realizado na Embrapa Trigo, em telado, em blocos ao acaso, com oito tratamentos e seis repetições, dispostos em parcelas subdivididas. As parcelas principais receberam os tratamentos com e sem infestação de pulgões, e as subparcelas foram compostas pelas cultivares. A infestação com os pulgões (20 adultos ápteros por planta) foi realizada aos 12 dias após a emergência das plantas, quando se encontravam no início do afilhamento, e foi mantida durante 15 dias. As cultivares avaliadas responderam diferentemente à infestação do pulgão R. padi. A cultivar BRS Timbaúva é a mais resistente, e as cultivares BRS Umbu e BRS Guabiju são as mais suscetíveis ao pulgão, quanto ao crescimento e a capacidade produtiva de plantas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPeruzzo, RafaelSalvadori, José RobertoPereira, Paulo Roberto Valle da SilvaTonello, Étel Carmen Bertollo Lucas Simionatto2007-12-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7749Pesquisa Agropecuaria Brasileira; v.42, n.12, dez. 2007; 1681-1685Pesquisa Agropecuária Brasileira; v.42, n.12, dez. 2007; 1681-16851678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/7749/4668info:eu-repo/semantics/openAccess2010-10-04T13:37:23Zoai:ojs.seer.sct.embrapa.br:article/7749Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-10-04T13:37:23Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
