Resumo: The objective of this work was to evaluate the potential damage of the green-belly stink bug, Dichelops melacanthus, to corn in greenhouse and field conditions. Three trials were carried out. In the greenhouse, corn plants in the V1 stage were evaluated after each of them was infested with one insect in four developmental stages (nymphs of the third, fourth, and fifth instars and adults) during 14 days. In the field, corn plants in four developmental stages (V1, V3, V5, and V7) were infested inside cages with five adult stink bugs, also during 14 days. In another trial in the greenhouse, the same treatments of the field trial were conducted during 14 days, but with an infestation intensity of one bug per plant per pot. The control treatment was without infestation. In all trials, damage scores were attributed to the corn plants and the dry matter of the aerial part of the plants was determined. In the field, stem diameter and grain yield were also evaluated. Third-instar nymphs do not cause significant changes in the dry weight of the aerial part of the plant and in the damage scores, compared with the control treatment. Infestations by adult stink bugs cause more damage to corn plants in the V1 and V3 stages, both in field and greenhouse conditions.

Foram realizados três ensaios. Na casa de vegetação, plantas de milho no estádio V1 foram avaliadas após cada uma ser infestada com um inseto em quatro estádios de desenvolvimento (ninfas de terceiro, quarto e quinto instar e adultos), durante 14 dias. No campo, plantas de milho em quatro estádios de desenvolvimento (V1, V3, V5 e V7) foram infestadas em gaiolas com cinco adultos do percevejo, também durante 14 dias. Em outro ensaio na casa de vegetação, os mesmos tratamentos do ensaio em campo foram conduzidos durante 14 dias, mas com intensidade de infestação de um percevejo por planta por vaso. O tratamento testemunha foi sem infestação. Em todos os ensaios, foram atribuídas notas de danos às plantas de milho e determinada a massa seca da parte aérea das plantas. No campo, também foram avaliados diâmetro do colmo e rendimento de grãos. As ninfas de terceiro instar não alteram significativamente o peso seco da parte aérea das plantas e as notas de danos, em comparação ao tratamento testemunha. Infestações de adultos do percevejo causam mais danos em plantas de milho nos estádios V1 e V3, tanto em condições de campo quanto de casa de vegetação.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFundação de Apoio ao Desenvolvimento do Ensino, Ciência e Tecnologia do Estado de Mato Grosso do Sul (Fundect)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes)Fernandes, Paulo Henrique RamosÁvila, Crébio JoséSilva, Ivana Fernandes daZulin, Daniele2020-06-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/26685Pesquisa Agropecuaria Brasileira; V.55, Jan./Dec., 2020: Publicação contínua em volume anual; e01131Pesquisa Agropecuária Brasileira; V.55, Jan./Dec., 2020: Publicação contínua em volume anual; e011311678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/26685/14704Direitos autorais 2020 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2022-05-18T18:26:38Zoai:ojs.seer.sct.embrapa.br:article/26685Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2022-05-18T18:26:38Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
