Resumo: The objectives of this research were to evaluate the chemical composition and bioactivity of the essential oil from the long-pepper leaves (Piper hispidinervum) and its effect on the comportment and/or mortality of the fall armyworm (Spodoptera frugiperda). The essential oil was obtained by steam stream distillation, using the modified Clevenger apparatus, the chemical composition was analyzed by GC-MS and GC. Tests of ingestion and topical application in fall armyworm of 1 st and 3 rd ínstar were made. The results showed that the long-pepper essential oil has insecticide activity on S. frugiperda, causing mortality and food reduction, and safrole (82%) as its majority constituent. Mortality was found in the ingestion test in larvae of 1 st ínstar LC50 = 16.2 mg/mL for larvae of 3 rd ínstar LC50 = 9.4 mg/mL, with reduced food CD50 = 0.72 mg/mL; and acute toxicity test of the contact topic with LD50 = 277.91 μg/larvae, after an interval of 96 hours, neurotoxicity symptoms were also observed, as knock-down effect.

O óleo essencial foi obtido pela técnica "arraste a vapor d'água", utilizando-se de um aparelho de Clevenger modificado, e posteriormente submetido, à análise por CG-EM e CG. Foram realizados testes de ingestão e contato tópico em lagartas de 1º e 3º ínstar. Os resultados constataram que o óleo essencial de pimenta-longa possui atividade inseticida sobre S. frugiperda, causando redução alimentar e mortalidade, sendo o safrol (82%) seu constituinte majoritário. Verificou-se mortalidade no teste de ingestão em lagartas de 1º ínstar com CL50 = 16,2 mg/mL e para lagartas de 3º ínstar a CL50 = 9,4 mg/mL com redução alimentar CD50 = 0,72 mg/mL; e de toxicidade aguda no teste de contato tópico com DL50 = 277,91 μg/lagarta, após o intervalo de tempo de 96 horas, sendo também observados sintomas de neurotoxicidade, como o efeito knock-down.Instituto Nacional de Pesquisas da Amazônia (INPA)2020-07-13T10:45:42Z2020-07-13T10:45:42Z2009info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfLIMA, R.
