Resumo: | The objective of this study was to characterize phenolic compounds and evaluate the effect, under laboratory conditions, of the cassava leaf powder methanol extract on the development of fall armyworm Spodoptera frugiperda and of leaf-cutting ant Atta sexdens rubropilosa. The extract was incorporated into an artificial diet, to which the armyworm was exposed, at concentrations of 250, 500, 1,000 and 1,500 mg kg-1, in order to evaluate biological characteristics. Soon after the insects emergence, another experiment was conducted to verify the possible sub lethal activity of the extract; therefore, S. frugiperda couples were isolated in cages and eggs were collected and counted. The Manihot esculenta Crantz extract caused a reduction in the percentage of armyworm survival, as well as in the eggs number. Then, the same extract was solubilized in 10% ethanol and applied to ants; mortality was observed, compared to the control. It is possible to conclude that the M. esculenta Crantz leaf powder methanolic extract, containing gallic acid and catechin, is a promising alternative to control S. frugiperda and Atta sexdens rubropilosa. |

Objetivou-se com o presente trabalho verificar o efeito do extrato metanólico da farinha das folhas de mandioca contra Spodoptera frugiperda e Atta sexdens rubropilosa. O referido extrato, em diferentes concentrações, foi incorporado na dieta, a qual foi exposta a lagarta para avaliar características biológicas. Logo após a emergência dos insetos, casais de S. frugiperda foram isolados em gaiolas para verificar a possível atividade sub-letal do extrato e as posturas foram recolhidas para a quantificação. O extrato de Manihot esculenta Crantz provocou redução na porcentagem de sobrevivência das lagartas, bem como no número de ovos. A seguir o mesmo extrato foi solubilizado em etanol 10 % e aplicado em formigas, observou-se a mortalidade em comparação com a testemunha. Os experimentos foram conduzidos em delineamento inteiramente casualizados. Os resultados obtidos demonstraram que o extrato metanólico da farinha das folhas de mandioca apresenta-se como uma alternativa promissora ao controle de S. frugiperda e de Atta sexdens rubropilosa, necessitando no entanto de novos estudos para isolamento e identificação das substâncias bioativas.UEL2013-12-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1284910.5433/1679-0359.2013v34n6Supl1p3501Semina: Ciências Agrárias; Vol. 34 No. 6Supl1 (2013); 3501-3512Semina: Ciências Agrárias; v. 34 n. 6Supl1 (2013); 3501-35121679-03591676-546Xreponame:Semina.
