Resumo: The potential insecticidal of oils from southwestern Amazon plants against Spodoptera frugiperda (J. E. Smith, 1797) (Lepidoptera: Noctuidae) was investigated. Initial bioassays were performed with undiluted oils from 11 plant species. The efficacy of the oils was evaluated against eggs and third-instar caterpillars of S. frugiperda. The oils of Copaifera sp. (Leguminosae), Orbignya phalerata (Arecaceae), and Carapa guianensis (Meliaceae) displayed a high efficacy against the caterpillars and were used in subsequent concentration-response bioassays, at concentrations established through preliminary tests. The highest nonlethal concentrations of oils and the lowest lethal concentrations were calculated. A completely randomized design was adopted in both bioassays. The LC50 of the oils varied from 7.50 to 60.84% (v/v). Copaifera sp. oil had the highest toxicity and was 6.84-fold more toxic than O. phalerata oil and 8.11-fold more toxic than Carapa guianensis oil. In general, oils from Copaifera sp., O. phalerata, and Carapa guianensis were effective in controlling S. frugiperda caterpillars under laboratory conditions, and are good candidates for use in integrated management programs of corn pests.

E. Smith, 1797) (Lepidoptera: Noctuidae). Inicialmente, foram realizados bioensaios utilizando-se óleos puros (sem diluições), oriundos de 11 espécies vegetais. A eficiência dos óleos foi avaliada para ovos e para lagartas de terceiro ínstar de S. frugiperda. Os óleos de Copaifera sp. (Leguminosae), Orbignya phalerata (Arecaceae) e Carapa guianensis (Meliaceae) apresentaram elevada eficiência para as lagartas de S. frugiperda, sendo, portanto utilizados nos bioensaios subsequentes de concentração-resposta. As concentrações de cada óleo, utilizadas nestes testes de concentração-mortalidade, foram estabelecidas por meio de testes preliminares. Estabeleceram-se as maiores concentrações dos óleos em que não ocorresse morte de insetos e as menores concentrações em que ocorresse a maior mortalidade. Com base nos dados obtidos, foram estabelecidos os intervalos definitivos. O delineamento inteiramente casualizado foi adotado em ambos os bioensaios. As CL50 variaram de 7,50 a 60,84% (v/v) entre os óleos. O óleo de Copaifera sp. apresentou maior toxicidade para as lagartas, sendo 6,84 vezes mais tóxico que o óleo de O. phalerata e 8,11 vezes mais tóxico que o óleo de Carapa guianensis. Em geral, os óleos de Copaifera sp., O. phalerata e Carapa guianensis são eficazes no controle de lagartas de S. frugiperda, sob condições de laboratório, destacando-se como candidatos a uso nos programas de manejo integrado das pragas do milho.Universidade Federal Rural do Semi-Árido2016-07-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/495010.1590/1983-21252016v29n314rcREVISTA CAATINGA; Vol. 29 No. 3 (2016); 642-647Revista Caatinga; v. 29 n. 3 (2016); 642-6471983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/4950/pdf_403Copyright (c) 2023 Revista Caatingainfo:eu-repo/semantics/openAccessSantos, Ana Cláudia Vieira dosFernandes, Carromberth CariocaLopes, Lucas MartinsSousa, Adalberto Hipólito2023-07-19T18:22:06Zoai:ojs.periodicos.ufersa.edu.br:article/4950Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:20.034282Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true
