Resumo: The objective of this work was to screen pathogenic isolates of Beauveria bassiana (Balsamo) Vüillemin from different hosts and geographic regions, pathogenic to the cotton boll weevil. Twelve isolates were evaluated. Isolates originally obtained from boll weevil showed low pathogenicity against this host. Insect mortality began on the second day after inoculation by fungal suspension, ranging from 15% to 83%, with a TL50 of 5.30 to 11.06 days. Variability among isolates concerning conidial germination in artificial culture medium was verified, and TG50 did not correlate with pathogenicity. One of the most virulent isolates of B. bassiana against cotton boll weevil is CG138.

Foram analisados 12 isolados em condições de laboratório. Os isolados obtidos originalmente de A. grandis foram pouco virulentos a essa praga. A mortalidade do bicudo teve início no segundo dia após a inoculação das suspensões fúngicas, variando de 15% a 83%, com TL50 entre 5,30 a 11,06 dias. Os isolados apresentaram variabilidade quanto à germinação dos conídios em meio de cultura artificial, e esta não se correlacionou com a patogenicidade. O isolado CG138 de B. bassiana destacou-se como um dos mais virulentos ao bicudo-do-algodoeiro.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSilva, Carlos Alberto Domingues da2001-02-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6125Pesquisa Agropecuaria Brasileira; v.36, n.2, fev. 2001; 243-247Pesquisa Agropecuária Brasileira; v.36, n.2, fev. 2001; 243-2471678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6125/3192info:eu-repo/semantics/openAccess2014-11-05T18:53:45Zoai:ojs.seer.sct.embrapa.br:article/6125Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-11-05T18:53:45Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
