Resumo: The effect of different concentrations of aqueous extracts of Melia azedarach on Spodoptera frugiperda biology was investigated under laboratory conditions. Corn leaves were immersed in solutions with extract concentrations of 0.1%; 1.0% and 5.0% and offered to newly-born larvae. At higher doses (1.0% and 5.0%) the extracts caused 100 % mortality of larvae. Observations of dead larvae showed abnormal moults and death at ecdysis. At the concentration of 0.1%, chinaberry extract increased the larval phase and reduced significantly the larval and pupal weight. Reproduction parameters, as the number of eggs per female, eggs per oviposition and eggs viability were affected using emerged adults from treated larvae with concentration of 0.1% Melia extract. The fecundity was drastically reduced. Survival and duration of egg stage were not affected by the extracts. No effect was observed in relation to attractiveness of caterpillars at first instar in tests with possibility of choice. The chinaberry aqueous extract showed good potential to be used as a control agent for S. frugiperda.

Folhas de milho foram imersas nos extratos (0,1%; 1,0% e 5,0%) e oferecidas a lagartas recém-eclodidas. Em doses elevadas (1,0% e 5,0%) os extratos causaram 100% de mortalidade larval. Observações das lagartas mortas indicaram mudas anormais e morte durante o processo de ecdise. Na concentração de 0,1% o extrato provocou o alongamento da fase larval e redução do peso das lagartas e pupas. Adultos provenientes de lagartas previamente intoxicadas com extrato a 0,1% apresentaram alterações em parâmetros reprodutivos tais como: número de ovos por fêmea, ovos por postura e viabilidade dos ovos. A fecundidade sofreu drástica redução. A sobrevivência dos ovos e a duração do período embrionário não foram afetadas em ensaios de atividade ovicida. Nenhum efeito foi observado em relação à atratividade alimentar de lagartas de primeiro ínstar em testes de arena com livre chance de escolha. Os resultados deste trabalho sugerem que o extrato aquoso de cinamomo apresenta potencial para o controle de S. frugiperda.   UEL2009-10-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/354210.5433/1679-0359.2009v30n3p537Semina: Ciências Agrárias; Vol. 30 No. 3 (2009); 537-550Semina: Ciências Agrárias; v. 30 n. 3 (2009); 537-5501679-03591676-546Xreponame:Semina.
