Resumo: | The objective of this work was to evaluate the performance of insecticides authorized on an emergency basis to control of Helicoverpa armigera (Lepidoptera: Noctuidae) in soybean. Seven insecticides were sprayed on the field and, 24 hours after that, soybean pointer leaves were collected and offered to 2nd instar larvae in the laboratory. Fourth instar larvae received the last trifoliate leaf that was fully expanded at the time of spraying. Another larvae group was exposed to leaves collected from 72 hours onwards after spraying. In the field, six insecticides were sprayed, and then the plants were infested with 2nd and 3rd instar larvae. In the first study, flubendiamide, chlorantraniliprole, chlorfenapyr, indoxacarb, and methoxyfenozide caused 100% mortality of the 4th instar, eight days after the beginning of exposure, while baculovirus and Bacillus thuringiensis (Bt) caused 60–75% mortality, which reached 88–90% at the end of the pupal stage. For 2nd instar larvae, only flubendiamide and chlorantraniliprole caused 100% mortality. Flubendiamide, chlorantraniliprole, and chlorfenapyr showed the lowest lethal time for the 4th instar, and flubendiamide and chlorantraniliprole for the 2nd instar. Seventy-two hours after spraying, the performance of insecticides was not satisfactory. In the field, there was satisfactory efficiency of flubendiamide, spinosad, baculovirus, and Bt on 2nd and 3rd instar larvae. |

Sete inseticidas foram pulverizados em campo e, após 24 horas, folhas do ponteiro foram coletadas e oferecidas para lagartas de 2o instar em laboratório. Lagartas do 4o instar receberam a última folha trifoliolada que se encontrava completamente expandida no momento da pulverização. Outro grupo foi exposto a folhas coletadas a partir de 72 horas da pulverização. Em campo, seis inseticidas foram pulverizados e, em seguida, as plantas foram infestadas com lagartas de 2o e 3o instar. No primeiro estudo, flubendiamida, clorantraniliprole, clorfenapir, indoxacarbe e metoxifenozida causaram 100% de mortalidade do 4o instar aos oito dias após o início da exposição, enquanto baculovírus e Bacillus thuringiensis (Bt) propiciaram mortalidade de 60–75%, que evoluiu para 88–90% ao final da fase de pupa. Para o 2o instar, apenas flubendiamida e clorantraniliprole proporcionaram mortalidade de 100%. Flubendiamida, clorantraniliprole e clorfenapir apresentaram o menor tempo letal para o 4o instar, e flubendiamida e clorantraniliprole, para o 2o instar. Após 72 horas da pulverização, o desempenho dos inseticidas foi insatisfatório. Em campo, houve eficiência satisfatória de flubendiamida, espinosade, baculovírus e Bt sobre lagartas de 2o e 3o instar.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCapes, Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorCapes, Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorKuss, Cassiano CarlosKuss-Roggia, Rejane Cristina RoppaBasso, Claudir JoséOliveira, Maria Cristina Neves dePias, Osmar Henrique de CastroRoggia, Samuel2016-08-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/20819Pesquisa Agropecuaria Brasileira; v.51, n.5, maio 2016: Número Temático Pesquisa, Desenvolvimento e Inovações em Face de Ameaças Sanitárias para a Agropecuária; 527-536Pesquisa Agropecuária Brasileira; v.51, n.5, maio 2016: Número Temático Pesquisa, Desenvolvimento e Inovações em Face de Ameaças Sanitárias para a Agropecuária; 527-5361678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/20819/13315https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/20819/12993Direitos autorais 2016 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2016-08-10T14:29:22Zoai:ojs.seer.sct.embrapa.br:article/20819Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2016-08-10T14:29:22Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
