Resumo: | With the large-scale emergence of diseases and pests in maize crops, the best solution to maintain maize yield and quality has been the use of Bt (Bacillus thuringiensis) technology, since it is a tactic which reduces the issues arising from insecticides. The aim of this study was to evaluate the incidence of Spodoptera frugiperda in transgenic and conventional maize hybrids and its phenotypic resistance. The experiment was carried out in Caceres - MT, on the 2nd crop of 2018, in a randomized block design, with three replications, evaluating six hybrids of a conventional version and thirteen transgenics. For the assessment of leaf damage caused by Spodoptera frugiperda, a visual scale of grades was used, with a variation of 0 to 9. The greatest damage caused by S. frugiperda was in the conventional hybrid AL Bandeirante, F2DAS2B710 x F2A2555, F2DAS2B710 x F230F35 and F2FORT x F2AG8060 and the least damage was to the conventional hybrid F2A2555 x F2FORT. Transgenic hybrids with greater S. frugiperda damage were DKB 230 PRO3, MG580 and DKB 290 PRO 3 and the least leaf damage was to the transgenic hybrid AG 8088 VT PRO with Viptera Technology®. Transgenic hybrids resistant to fall armyworm can be discriminated by scouting for insect resistance at DSF 45 (45 days) and DSF 60 (60 days). |

O presente trabalho teve por objetivo avaliar a incidência de Spodoptera frugiperda em híbridos de milho transgênicos e convencionais e sua resistência fenotípica. O experimento foi realizado em Cáceres – MT, na 2ª safra de 2018, em delineamento experimental de blocos ao acaso, com três repetições, avaliando-se seis híbridos na versão convencional e treze transgênicos. Para a avaliação dos danos foliares ocasionados por Spodoptera frugiperda, utilizou-se de uma escala visual de notas, com variação de 0 a 9. Os maiores danos ocasionados por S. frugiperda foram nos híbridos convencionais AL BANDEIRANTE, F2DAS2B710 x F2A2555, F2DAS2B710 x F230F35 e F2FORT x F2AG8060 e de menor dano no híbrido convencional F2A2555 x F2FORT. Híbridos transgênicos com maiores danos por S. frugiperda foram DKB 230 PRO3, MG580 e DKB 290 PRO 3 e de menor dano foliar o híbrido transgênico AG 8088 VT PRO com tecnologia Viptera®. Pode-se discriminar híbridos transgênicos resistentes à lagarta-do-cartucho através do monitoramento de resistência à inseto realizado aos DSF 45 e DSF 60.Editora Uningá2019-12-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontextoapplication/pdfhttps://revista.uninga.br/uningareviews/article/view/3350Uningá Review ; Vol. 34 No. 4 (2019): Revista UNINGÁ Review; 12-23Uningá Review Journal; v. 34 n. 4 (2019): Revista UNINGÁ Review; 12-232178-2571reponame:UNINGÁ Reviewinstname:Centro Universitário Uningáinstacron:UNINGAporhttps://revista.uninga.br/uningareviews/article/view/3350/2195Copyright (c) 2020 REVISTA UNINGÁ REVIEWinfo:eu-repo/semantics/openAccessBernini, Cristiani SantosOliveira, Thais AlvesFigueiredo, Zulema Netto2020-06-19T21:16:08Zoai:ojs.revista.uninga.br:article/3350Revistahttps://revista.uninga.br/uningareviews/indexPUBhttps://revista.uninga.br/uningareviews/oairevistauningareview@uninga.edu.br || sec.revistas@uninga.edu.br2178-25712178-2571opendoar:2020-06-19T21:16:08UNINGÁ Review - Centro Universitário Uningáfalse |
