Resumo: The aim of this study was to evaluate the pathogenicity of Verticillium lecanii isolates against Cinara atlantica, and the LC50 of the best strain. For selection tests, nymphs of C. atlantica were placed on individual pine seedling with 20 isolates and one control, in a total of 21 treatments and ten replicates. For the LC50 estimation it was used the CG 904 strain with six concentrations and ten replicates. VL 6, CG 902 and VL 2 produced the highest mortality, of 72.22%, 67.34% and 67.31%, respectively. The control plot showed mortality of 15.6%. The LC50 of the CG 904 strain indicated mortality of 100% at the concentration of 108 conidia mL-1; LC50, 2x105 conidia mL-1; and LT50, 4.4 days.

No teste de seleção, utilizaram-se mudas de pinus com ninfas do pulgão, 20 isolados do fungo e um controle, num total de 21 tratamentos e dez repetições. Na CL50 do isolado CG 904, utilizaram-se seis concentrações, com dez repetições. VL 6, CG 902 e VL 2 apresentaram os mais altos índices de mortalidade, 72,22%, 67,34% e 67,31%, respectivamente. A testemunha apresentou mortalidade de 15,6%. Nos bioensaios de CL50, a concentração de 108 conídios mL-1, do isolado CG 904, causou mortalidade de 100%, CL50 de 2x105 conídios mL-1 e TL50 de 4,4 dias.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraLeite, Maria Silvia PereiraPenteado, Susete do Rocio ChiarelloZaleski, Scheila Ribeiro MessaCamargo, Joelma Melissa MalherbeRibeiro, Rodrigo Daniel2005-11-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7076Pesquisa Agropecuaria Brasileira; v.40, n.11, nov. 2005; 1141-1144Pesquisa Agropecuária Brasileira; v.40, n.11, nov. 2005; 1141-11441678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/7076/4124info:eu-repo/semantics/openAccess2014-09-19T18:00:09Zoai:ojs.seer.sct.embrapa.br:article/7076Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-19T18:00:09Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
