“…Among the compounds that are synthesized by the secondary metabolism of plants, terpenoids are a rich source of bioactive molecules that exhibit toxicity to various pests (Ali et al, 2010;Lima et al, 2013;Lima et al, 2009;Silva et al, 2010). Some studies have shown that these compounds act as inhibitors of AChE, impair oviposition (Alexenizer;Dorn, 2007;Cavalcante;Vasconcelos, 2006) and cellular respiration (Yu, 2008) and act as synergists of other bioactive agents (Fazolin et al, 2016).…”

For an important and expensive crop such as corn, the resistance of Spodoptera frugiperda J.E. Smith to various pesticides has led to research throughout the world for a potential insecticide from a natural source. For the management of pest resistance, natural compounds associated with synthetic insecticides can be a promising tool because they can reduce the application of the synthetics molecules while maintaining their effectiveness and promoting the control of the pests. Linalool is a potential insecticide that is easily obtained because it is found in high concentrations in the essential oil of Ocimum basilicum L. Therefore, the present study aimed to evaluate the toxicity of this essential oil and its combination with deltamethrin to control S. frugiperda. Through dose response assays, the acute toxicities (LD 50 ) of the essential oil and deltamethrin were estimated. Additionally, the combination of these materials was also assessed, attaining a reduction of 80% of the LD 50 of deltamethrin while obtaining the same result as when the pyrethroid was administered alone. From these results, it is expected that the combination of natural compounds and synthetic insecticides will be a promising practice, helping to manage resistance while reducing the environmental impact of toxic compounds.Index terms: Natural insecticides; linalool; fall armyworm; pyrethroid; synergism. RESUMOPara uma cultura importante e expressiva como o milho, a resistência de Spodoptera frugiperda J.E. Smith a vários inseticidas atraiu a atenção no mundo para pesquisar o potencial inseticida de compostos naturais. Para o manejo da resistência, os compostos naturais associados a inseticidas sintéticos podem ser uma ferramenta promissória por reduzirem a aplicação das moléculas sintéticas para que não percam sua eficácia, além de promover o controle das pragas. O linalol é um terpenoide considerado como inseticida potencial, pode ser facilmente obtido naturalmente uma vez que é encontrado em alta concentração no óleo essencial de Ocimum basilicum. Portanto, o presente estudo teve como objetivo avaliar a toxicidade deste óleo essencial e sua combinação com deltametrina no controle de Spodoptera frugiperda. Através do ensaio de dose-resposta, foi estimada a toxicidade aguda (DL50) do óleo essencial e da deltametrina. Adicionalmente, foi também avaliada a combinação entre ambos, alcançando uma redução de 80% da DL 50 de deltametrina para se obter o mesmo resultado quando o piretroide foi administrado sozinho. A partir dos nossos resultados, espera-se que uma combinação de uso de compostos naturais e inseticidas sintéticos possa ser uma prática promissora, auxiliando no manejo da resistência de pragas e principalmente reduzindo os impactos ambientais de compostos tóxicos.

“…[43] evaluated the insecticidal activity of the essential oil of P. hispidinervum, collected in Lavras in the state of Minas Gerais, on Spodoptera frugiperda (Fall armyworm), atributing the efect to safrole (82%), the major component of the essential oil being analyzed. The essential oil of Piper betle showed insecticidal activity by inhibiting the development of Spodoptera litura pupae without causing damage to the Eudrilus eugeniae organism [56].…”

Piperaceae, a Latin name derived from Greek, which in turn originates from the Arabic word babary-black pepper, is considered one of the largest families of basal dicots, found in tropical and subtropical regions of both hemispheres. The species that belong to this family have a primarily pantropical distribution, predominantly herbaceous members, occurring in tropical Africa, tropical Asia, Central America and the Amazon region. The Piperaceae family includes ive genera: Piper, Peperomia, Manekia, Zippelia and Verhuellia.Brazil has about 500 species distributed in the Piper, Peperomia and Manekia genera. The Piper genus, the largest of the Piperaceae family, has about 4000 species. Within the Piper genus, about 260-450 species can be found in Brazil. Piper species have diverse biological activities and are used in pharmacopeia throughout the world. They are also used in folk medicine for treatment of many diseases in several countries including Brazil, China, India, Jamaica and Mexico. Pharmacological studies of Piper species point toward the vast potential of these plants to treat various diseases. Many of these species are biologically active and have shown antitumor, antimicrobial, antioxidant, insecticidal, antiinlammatory, antinociceptive, enzyme inhibitor, antiparasitic, antiplatelet, piscicide, allelopathic, antiophidic, anxiolytic, antidepressant, antidiabetic, hepatoprotective, amebicide and diuretic possibilities.

ABSTRACT:The aim of this study was to assess the chemical composition of essential oils of Illicum verum, Ageratum conyzoides, Piper hispidinervum and Ocotea odorífera, as well as their toxicity to the green-aphid Schizaphis graminum. Compound identification was carried out with gas chromatography + mass spectrometry, and quantification with gas chromatography + flame ionization detector, both with DB5 column. The hydrodistillation process promoted oil yield of 3.81% for I. verum; 0.46% for A. conyzoides; 2.85 % for P. hispidinervum; and 0.68 % for O. odorífera. The major components from the oils of A. conyzoides was precocene (87.0%) and (E)-caryophyllene (7.1%); (E)-anethol (90.4%), limonene (2.6%) and methyl-chavicol (1.3%) for I. verum; methyleugenol (81.2%) and safrole (10.6%) for O. odorifera; and safrole (82.5%) and α-terpinolene (13.4%) for P. hispidinervum. The acute toxicity test (24 hours) performed by contact in sorghum leaves or contaminated filter-paper showed that the higher toxicity occur with essential oils of A. conyzoides, with LC 50 of 7.01 and 7.01 µg oil/cm 2 , respectively; followed by O. odorifera, with LC 50 of 17.10 and 66.70 µg oil/cm 2 , respectively; I. verum, with LC 50 of 66.40 and 65.40 µg oil/cm 2 , respectively; and low toxicity was observed for the P. hispidinervum essential oil, with LC 50 of 64.00 and 143.00 oil/cm 2 , respectively. With the results obtained in this research, we can state that the use of these essential oils can be a new tool in integrated pest management.
