Resumo: | The objective of this work was to evaluate the circadian feeding rhythm of the green-belly stink bug (Dichelops melacanthus) on corn (Zea mays), and to correlate it with meteorological parameters. The experiments were conducted in corn fields in the first (summer) and second (fall) crop seasons, in the municipality of Chapecó, in the state of Santa Catarina, Brazil. Plants in the V3 and V5 stages were covered with cages and infested with adults of D. melacanthus. After 24 hours of acclimation, the number of insects feeding on the plant stem was counted every three hours (at 6:00, 9:00, 12:00, 15:00, 18:00, 21:00, and 0:00 h). At night, a red led flashlight was used to visualize the insects without interfering with their behavior. Meteorological parameters were monitored and correlated to the number of insects feeding on the plants. In the first and second crop seasons, the number of insects feeding on the corn stem differed among evaluation times, with peak in the afternoon, in the evening, and at night. Few insects were found feeding at 6:00 and 9:00 h. There was a positive correlation between air temperature and feeding in both seasons. In milder temperature regions, the preferred feeding time of D. melacanthus on corn is during the afternoon, evening, and night hours, which should be taken into account for a precise management of this insect. |

Os experimentos foram realizados em cultivos de milho de primeira (verão) e segunda safras (outono), no município de Chapecó, no estado de Santa Catarina, Brasil. Para isso, plantas nos estágios V3 e V5 foram cobertas por gaiolas e infestadas com adultos de D. melacanthus. Após 24 horas de aclimatização, o número de insetos que se alimentava no colmo das plantas foi mensurado a cada três horas (às 6:00, 9:00, 12:00, 15:00, 18:00, 21:00 e 0:00 h). Para avaliações noturnas, utilizou-se uma lanterna com led vermelho, para visualizar os insetos sem interferir em seu comportamento. Parâmetros meteorológicos foram monitorados e correlacionados com o número de insetos que se alimentava nas plantas. Nas primeira e segunda safras, o número de insetos que se alimentava nos colmos de milho diferiu entre os horários avaliados, com maior abundância à tarde e à noite. Poucos insetos foram observados alimentando-se às 6:00 e 9:00 h. Houve correlação positiva entre a temperatura do ar e a alimentação, em ambas as safras. Em regiões de clima mais ameno, o período preferido para alimentação de D. melacanthus em milho é nas horas da tarde e da noite, o que deve ser levado em consideração para um manejo eficiente desse inseto.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCastilhos, Rodolfo VargasRibeiro, Leandro do PradoCarvalho, Gabriel de2020-12-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/26840Pesquisa Agropecuaria Brasileira; V.56, Jan./Dec., 2021: Publicação contínua em volume anual; e02123Pesquisa Agropecuária Brasileira; V.56, Jan./Dec., 2021: Publicação contínua em volume anual; e021231678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/26840/14817Direitos autorais 2020 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2022-05-18T18:27:35Zoai:ojs.seer.sct.embrapa.br:article/26840Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2022-05-18T18:27:35Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
