Resumo: | The area cultivated with wheat has been increasing in the savannahs of the state of Minas Gerais, Brazil. Aphids are usually one of the main pests of wheat in many regions of the world; however, little is known about the aphid population in this new environment. The southern region of Brazil, the main wheat production area, has had several problems as a result of aphids, but aphid populations and the resulting impact on wheat production have not been investigated in these new crop production areas. Understanding control strategies to manage this insect could be essential for the “Cerrado” wheat that is grown in this area. The application of silicon (Si) has the potential to reduce the population growth of wheat aphids; however no field studies have been reported. Hence, we evaluated the effect of Si fertilization via soil application on the aphid populations and species composition and on yield components of wheat in three locations in Minas Gerais; the experiment was repeated simultaneously in Uberlândia, at the experimental areas of UFU and IFTM, and in Montes Claros, at the experimental area of UFMG, using the cultivars BRS 264 and BRS 394. The aphids first appeared just before wheat earing; they were then sampled six times over the course of the study, seven days apart, starting from 45 days after sowing. The aphid species Sitobion avenae (Fabricius), Schizaphis graminum (Rondani), and Rhopalosiphum padi (Linnaeus) were observed in all three locations; S. avenae was the dominant species in all locations. The experimental area of UFU had the highest number of S. avenae aphids per tiller for both cultivars, while UFMG had the lowest populations. Aphid populations and wheat yield components were not affected by soil Si fertilization. There was no difference in yield as a result of location or cultivar, but the location UFU and the cultivar BRS 394 had the greatest average hectoliter weight. |

Afídeos são frequentemente a principal praga dessa cultura em várias regiões do mundo porém, pouco se sabe a respeito de população de afídeos nesse novo ambiente. A região sul do Brasil, principal produtora de trigo, relatou vários problemas resultantes da presença de afídeos, mas as populações de pulgões e os seus impactos na produção do trigo ainda não foram investigados nesta nova área de produção. Portanto, é necessário conhecer a interação sobre pragas, culturas, e paisagens. Entender estratégias de controle para gerenciar esse inseto pode ser essencial para o trigo “Cerrado”. A aplicação de silício (Si) tem o potencial de reduzir o crescimento populacional de pulgões do trigo, porém não há relatos de estudos de campo. Nós avaliamos os efeitos da aplicação via solo de Si sobre populações de afídeos e sobre a composição de espécies, além de componentes de produtividade em três localidades em Minas Gerais. O experimento foi repetido simultaneamente em Uberlândia, nas áreas experimentais da UFU e do IFTM, e em Montes Claros, na área experimental da UFMG, utilizando as cultivares BRS 264 e BRS 394. Os primeiros pulgões ocorreram antes da formação da espiga, e os mesmos foram amostrados seis vezes ao longo do estudo, com sete dias de intervalo, iniciando 45 dias após a semeadura. As espécies de afídeo Sitobion avenae (Fabricius), Schizaphis graminum (Rondani) e Rhopalosiphum padi (L.) foram observadas nos três locais e S. avenae foi a espécie dominante em todos os locais. A área experimental da UFU apresentou o maior número de pulgões de S. avenae por perfilho para as duas cultivares, enquanto a UFMG apresentou as menores populações. As populações de afídeos e os aspectos de produção do trigo não foram afetados pela fertilização de Si no solo. Não houve diferenças de produtividade para a localização ou cultivares, mas a área de UFU e a cultivar BRS 394 tiveram o maior peso médio hectolitro.UEL2020-09-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3765110.5433/1679-0359.2020v41n6p2481Semina: Ciências Agrárias; Vol. 41 No. 6 (2020); 2481-2494Semina: Ciências Agrárias; v. 41 n. 6 (2020); 2481-24941679-03591676-546Xreponame:Semina.
