Resumo: | Known as green insecticides, natural plant-based products have become a promising alternative to conventional insecticides. The primary objective of the present study was to analyze, under laboratory conditions, the insecticidal activity of crude ethanol extracts of the fern species Dicksonia sellowiana and Nephrolepis cordifolia against Oncopeltus fasciatus (Hemiptera). Fern leaves were collected from Itatiaia National Park (Brazil), dried and ground using 96% ethanol, with the extract concentrated in a rotary evaporator. The crude extract was used to prepare a 50 mg/mL solution, with acetone as solvent. Qualitative analysis of the terpenoid and phenolic substance profile in the extracts was performed by thin-layer chromatography (TLC). Fourth-instar insects were used, in groups of 10 animals per treatment, with three repetitions. Four treatments were used: D. sellowiana and N. cordifolia extracts, acetone control and water control. Then, 1 μL either of the respective solution was topically applied to the insect abdominal cuticle. After 21 days, all the insects in the water control group had reached adult. The N. cordifolia extract was responsible for 63% (p < 0.0001) of insect mortality around 16 days after treatment, whereas the D. sellowiana exhibited 50% (p < 0.0001) on the 21st day post-treatment. The extracts also caused delays in insect molting and metamorphosis. The D. sellowiana and N. cordifolia extracts exhibited 18% similarity in the terpenoid profile and 0% for phenolic substances. N. cordifolia and D. sellowiana show potential for research on selective biodegradable substances for use as green insecticides. |

El presente documento tiene por objeto evaluar la actividad insecticida de los extractos etanólicos brutos de helechos, Dicksonia sellowiana y Nephrolepis cordifolia en Oncopeltus fasciatus (Hemiptera). Las hojas se colectaron en el Parque Nacional Itatiaia (Brasil), se secaron, se maceraron con 96% de etanol y el extracto se concentró en un evaporador rotativo. A partir del extracto crudo se preparó una solución a una concentración de 50 mg/mL, utilizando acetona como disolvente. El análisis cualitativo del perfil de las sustancias terpenoides y fenólicas se realizó mediante cromatografía en capa fina. Se usaron insectos en su 4º estadio en grupos de 10 animales por triplicado por tratamiento. En cada grupo se aplicaron tópicamente las siguientes soluciones a la cutícula abdominal de los insectos 1 μL: extracto de D. sellowiana, de N. cordifolia, control de agua y control de acetona. Después de 21 días todos los insectos del grupo control de agua habían alcanzado la edad adulta. El extracto de N. cordifolia fue responsable del 63% (p < 0,0001) de la mortalidad de los insectos alrededor del 16º día después del tratamiento, mientras que el extracto de D. sellowiana presentó un 50% (p < 0,0001) al 21º día después del tratamiento. Los extractos también promovieron retrasos en el período de muda y metamorfosis de los insectos. Los extractos de D. sellowiana y N. cordifolia mostraron una similitud del 18% en el perfil terpenoide y del 0% para las sustancias fenólicas. N. cordifolia y D. sellowiana presentan un potencial prometedor para la investigación de sustancias para su uso como insecticidas verdes.Conhecidos como inseticidas verdes, os produtos naturais de origem vegetal têm se revelado uma promissora alternativa aos inseticidas convencionais. O presente trabalho teve como objetivo avaliar a atividade inseticida dos extratos etanólicos brutos das samambaias, Dicksonia sellowiana e Nephrolepis cordifolia sobre Oncopeltus fasciatus (Hemiptera). As folhas foram coletadas no Parque Nacional de Itatiaia, secas, maceradas com etanol 96% e o extrato concentrado em evaporador rotatório. A partir do extrato bruto foi preparada uma solução na concentração de 50 mg/mL, usando acetona como solvente. A análise qualitativa do perfil de terpenoides e substâncias fenólicas foi realizada por meio de cromatografia em camada delgada. Foram utilizados insetos no 4º ínstar em grupos de 10 animais em triplicatas por tratamento. Em cada grupo foi topicamente aplicado à cutícula abdominal dos insetos 1 μL das seguintes soluções: extrato de D. sellowiana, de N. cordifolia, controle água e controle acetona. Após 21 dias todos os insetos do grupo controle negativo (água) haviam atingido a idade adulta. O extrato de N. cordifolia foi responsável por 63% (p < 0,0001) de mortalidade nos insetos, em torno do 16º dia após o tratamento, enquanto que o extrato de D. sellowiana apresentou 50% (p < 0,0001) no 21º dia após o tratamento. Os extratos também promoveram atrasos no período de muda e metamorfose dos insetos. Os extratos de D. sellowiana e N. cordifolia apresentaram similaridade de 18% no perfil de terpenoides e 0% para substâncias fenólicas.
