Resumo: Abstract: The green belly stink bug Dichelops furcatus (Fabr.) (Hemiptera: Pentatomidae) is a key pest of maize, causing damage by both sucking sap and by injecting toxins that affect the normal plant development. In order to assess the economic injury level (EIL) of this stink bug to maize, an experiment at field was conducted in Chapecó, in January 2014 in a complete randomized block design. The treatments were constituted by different populational levels (0, 2, 4, 8, and 17) of D. furcatus adults which were released in cages with 12 maize plants (experimental units). The evaluations were performed by means of both number of plants count with insect attack symptoms 25 days after plant emergence and grain productivity. The increasing population of D. furcatus caused a linear increase of symptomatic plants and a strong reduction in the grain productivity. The EIL for D. furcatus in maize was estimated according to the cost of pest control and value of corn in the market. Considering a corn value ranging between R$12 to R$36 a bag of 60 kg and with cost of control ranging between R$40 to R$160 per hectare, the EIL was always below of 0.5 adult per meter of maize plants.

(Hemiptera: Pentatomidae), é uma praga-chave da cultura do milho, que causa o danos tanto pela sucção de seiva quanto pela injeção de toxinas que afetam o desenvolvimento normal das plantas. Para estabelecer o nível de dano econômico (NDE) dessa praga na cultura do milho, foi instalado, em janeiro de 2014, um experimento no campo, em Chapecó, SC, adotando delineamento em blocos aleatorizados. Os tratamentos foram com diferentes níveis populacionais (0, 2, 4, 8 e 17) de percevejos adultos, liberados em gaiolas com 12 plantas de milho (unidades experimentais). As avaliações constaram da contagem do número de plantas sintomáticas após 25 dias da emergência das plantas e a produtividade de grãos. O aumento do nível populacional de D. furcatus ocasiona crescimento linear no número de plantas sintomáticas e redução significativa na produtividade. O NDE para D. furcatus na cultura do milho situa-se sempre abaixo de 0,5 percevejo por metro de plantas em cenários de preço do milho variando de R$12 a R$36 a saca de 60kg e custo de controle da praga variável entre R$40 e R$160 por hectare. 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/93Agropecuária Catarinense Journal; Vol. 29 No. 1 (2016); 63-67Agropecuária Catarinense; v. 29 n. 1 (2016); 63-672525-60760103-0779reponame: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/93/29Copyright (c) 2016 Revista Agropecuária Catarinenseinfo:eu-repo/semantics/openAccessChiaradia, Luís AntônioNesi, Cristiano NunesRibeiro, Leandro do Prado Ribeiro Prado2020-07-06T04:18:44Zoai:ojs.publicacoes.epagri.sc.gov.br:article/93Revistahttps://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:2020-07-06T04:18:44Agropecuária Catarinense (Online) - Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)false
