dc.description.abstract | The effects of plant extracts from Actinostemon concolor, Geonoma schottiana, Palicourea rigida and Rudgea viburnoides on Spodoptera frugiperda were evaluated in this study. The extracts were incorporated into an artificial diet (1 mg mL-1 of diet) and offered to S. frugiperda caterpillars. The extract of A. concolor caused 36.1 % mortality in S. frugiperda. Ultrastructural changes were detected in the eggs of adults when the caterpillars were fed with P. rigida and A. concolor extracts. A reduction in trypsin activity was observed after treatment with A. concolor extract. Total phenolics were quantified for A. concolor, G. schottiana, P. rigida and R. viburnoides, with A. concolor presenting the highest content. The residue from methanol/water extraction, which was obtained from the crude extract of A. concolor, contained the phenolic compounds that caused changes in S. frugiperda biology similar to those caused by the crude extract. In conclusion, A. concolor produces secondary metabolites that have insecticidal activity on S. frugiperda. | pt_BR |

dc.description.resumo | Los efectos de extractos de las plantas Actinostemon concolor, Geonoma shottiana, Palicourea rigida y Rudgea viburnoides sobre Spodoptera frugiperda fueron evaluados en este estudio. Los extratos se incorporaron en la dieta artificial (1 mg mL-1 de la dieta) y se ofrecieron a larvas de S. frugiperda. El extracto de A. concolor causó 36,1 % de mortalidad. Se detectaron cambios ultraestructurales en los huevos de adultos alimentados en sus estados larvales con extractos de P. rigida y A. concolor. Se observó reducción de la actividad de la tripsina de S. frugiperda después del tratamiento con el extracto de A. concolor. Al cuantificar los fenoles totales en A. concolor, G. shottiana, P. rigida y R. viburnoides, se encontró que A. concolor fue la especie con mayor contenido. El residuo de metanol/agua extracción, que se obtuvo del extracto crudo de A. concolor, contenía compuestos fenólicos que causan cambios en la biología de S. frugiperda similar a los generados por el extracto crudo. En conclusión, A. concolor produce metabolitos secundarios con actividad insecticida sobre S. frugiperda. | pt_BR |
