Resumo: The South American rice water weevil, Oryzophagus oryzae (Costa Lima) (Coleoptera: Curculionidae), is one of the most important insect pest of irrigated rice in Brasil. The Beauveria bassiana (Bals.) Vuill. application in rice fields did not result in biological control of the pest, despite its susceptibility to the entomopathogenic fungus. So, the aim of this research was to evaluate the artificial infection of O. oryzae adults with B. bassiana in light trap. Two light traps were set in an irrigated rice field and one received an apparatus of fungal contamination. The captured insects, in five dates, were kept in laboratory to check the mortality by B. bassiana infection. Fungal mortality rates of individuals that went through the apparatus varied from 85.8 to 97.9%, expressing exponential mortality curves. This result shows that light traps, equipped with B. bassiana inoculum, are efficient to infect artificially adults of O. oryzae.

A aplicação de Beauveria bassiana (Bals.) Vuill. nas lavouras não tem resultado no controle biológico da praga, apesar da suscetibilidade a esse entomopatógeno. Assim, foi objetivo desta pesquisa avaliar a infecção artificial de adultos de O. oryzae com B. bassiana em armadilha luminosa. Duas armadilhas luminosas foram instaladas em lavoura de arroz irrigado em Itajaí, SC, sendo uma delas com um aparato de contaminação fúngica. Os insetos capturados, em cinco datas, foram mantidos em laboratório para avaliar a mortalidade por infecção desse entomopatógeno. As taxas de mortalidade por infecção fúngica dos insetos oriundos da armadilha com B. bassiana variaram de 85,8% a 97,9%, expressando curvas de mortalidade exponenciais. Esse resultado evidencia que armadilhas luminosas equipadas com inoculo de B. bassiana são eficientes para infectar artificialmente adultos de O. oryzae.  Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina - Epagri2017-10-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://publicacoes.epagri.sc.gov.br/rac/article/view/182Agropecuária Catarinense Journal; Vol. 28 No. 1 (2015); 74-77Agropecuária Catarinense; v. 28 n. 1 (2015); 74-772525-60760103-0779reponame:Agropecuária Catarinense (Online)instname:Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)instacron:EPAGRIporhttps://publicacoes.epagri.sc.gov.br/rac/article/view/182/90Copyright (c) 2017 Revista Agropecuária Catarinenseinfo:eu-repo/semantics/openAccessHickel, Eduardo RodriguesMilanez, José MariaHinz, Robert Harri2020-07-07T04:48:00Zoai:ojs.publicacoes.epagri.sc.gov.br:article/182Revistahttps://publicacoes.epagri.sc.gov.br/RAC/indexPUBhttps://publicacoes.epagri.sc.gov.br/index.php/RAC/oaieditoriarac@epagri.sc.gov.br || lamperuch@epagri.sc.gov.br2525-60760103-0779opendoar:2020-07-07T04:48Agropecuária Catarinense (Online) - Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)false
