Resumo: | The root aphid Rhopalosiphum rufiabdominale (Sasaki, 1899) infestation and damage were studied in an experiment of upland rice mechanization using the cultivar Caiapó. The five sowing machines and the two soil preparations used showed significant differences in the percentage of infested plants and plant population. The Caiapó grain yield was estimated to have been reduced by the aphid in about 28.5%, being 15.2% associated to missing plants and 13.3% to the feebleness of the remaining plants. To reduce the insect damage, the first step is to choose an adequate sowing machine, followed by a correct soil preparation and treatment when the crop infestation shows, at the beginning of tillering and reproductive phases, respectively, 13% and 5% of the plants with aphid colonies on the roots. |

Os tipos de semeadoras utilizados e os modos de preparo do solo apresentaram diferenças significativas nas porcentagens de plantas infestadas pelo afídeo e de falhas na população de plantas. Estimou-se que o inseto reduziu o rendimento de grãos da Caiapó em 28,5%, sendo 15,2% associados às falhas no estande, e 13,3%, à depauperação das plantas remanescentes. A orientação para reduzir o dano causado pelo inseto indica, como primeiro passo, a escolha da semeadora adequada, seguida do preparo do solo e da aplicação de tratamento, quando o monitoramento das lavouras mostrar, no início das fases de afilhamento e reprodutiva, respectivamente, 13% e 5% das plantas com colônias de afídeos nas raizes.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFerreira, EvaneSilva, José Geraldo daZimmermann, Francisco José P.Silva, Daniela Rezio e1995-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/4416Pesquisa Agropecuaria Brasileira; v.30, n.10, out. 1995; 1211-1215Pesquisa Agropecuária Brasileira; v.30, n.10, out. 1995; 1211-12151678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/4416/1702info:eu-repo/semantics/openAccess2011-08-25T13:03:37Zoai:ojs.seer.sct.embrapa.br:article/4416Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2011-08-25T13:03:37Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
