“…The essential oils (EOs) of some species may present toxic compounds for insects, but are safe for humans, thus with a high potential to control agricultural pests (EBADOLLAHI, 2011). Some EOs extracted from certain plant species have the capacity to repel and/or kill through direct contact and even through the respiratory system (ISMAN, 2000;CORRÊA;SALGADO, 2011). The secondary metabolism of the plants synthesize these oils using all their organs and have a communication (e.g., attracting pollinators) and defense function (BAKKALI et al, 2008).…”

Fall armyworm, Spodoptera frugiperda (Smith) (Lepidoptera: Noctuidae) is one of the main pests in maize crop with developing resistance to chemical products and Bt technology. Therefore, alternative control methods such as essential oils are important steps in the implementation management strategies for this pest. This study aimed to evaluate the efficiency of essential oils (EOs) of Corymbia citriodora, Myrciaria dubia (Myrtaceae), Lippia microphylla (Verbenaceae) and Piper umbelattum (Piperaceae) in controlling S. frugiperda. The OEs were extracted and mortality tests were conducted with topic and volatile applications, in 30 second-instar caterpillars originated from insect rearing and artificial diet. As a control, we conducted tests with distilled water and acetone. EOs that provided mortality rates above 80% were submitted to chemical analysis for constituent identification. The efficient EOs were only those of C. citriodora and L. microphylla. For EO of C. citriodora, the LD80 was 7.06 ± 0.73 mg.g -1 in topical application and 5.85 ± 0.75 μL via volatile application. On the other hand, for EO of L. microphylla, DL80 was 9.95 ± 1.25 mg.g -1 in topical application and 18.56 ± 3.55 μL via volatile application. Chemical analysis showed that the main constituents were citronella for the EO of C. citriodora and (E)-caryophyllene and (E)-nerolidol to the EO of L. microphylla. EOs of C. citriodora and L. microphylla are promising for controlling S. frugiperda, with emphasis on the volatile effect of C. citriodora oil.

Present study was aimed to characterize the phytochemical profile of the leaf extracts of Spondias sp and Spondias tuberose. During study total five trees of Spondias sp (Cajarana do sertão) and Spondias tuberosa (Umbu) with good phytosanitary was used for phytochemical analysis. From these selected trees total 5kg leaves per tree were collected and air dried at 40°C. These leaves samples were ground and pulverized; from this 200g of powder sample were used to prepare ethanolic crude extract and phytochemical analysis was performed at the Laboratory of Pharmaceutical Technology, Federal University of Paraíba. The phytochemical screening was carried out by preliminary scouting method for identify the presence of alkaloids, steroids, tannins, flavonoids, terpenoids, and saponins. Results of study revealed that the presence of steroids, tannins, flavonoids and terpenoids from the leaf extracts of Spondias sp and Spondias tuberosa , these phytochemicals are important constitute of herbal medicines and pharmaceutical industry and worked as antioxidant, anti-infective, anti-allergic and anti inflammatory agents.

“…Usually, botanical insecticides are used as powders, extracts or oils, which are easy to obtain, and generally harmless to the applicator and consumers (ISMAN, 2000;CORRÊA;SALGADO, 2011). More than 100,000 secondary metabolites with insecticidal properties have been identified from approximately 200,000 species of plants in the world, and they particularly belong to alkaloid, terpenoid, flavonoid, and quinone groups (POTENZA et al, 2004).…”

Potentiation of Copaíba Oil-Resin With Synthetic Insecticides to Control of Fall Armyworm

et al. 2017

-The control of Spodoptera frugiperda (J. E. SMITH) (Lepidoptera: Noctuidae) has been carried out mainly with pyrethroids and organophosphates insecticides. The continuous and indiscriminate use of synthetic insecticides, for decades, has led to the selection of resistant populations and has caused concerns for human health and the environment. An alternative is the use of botanical insecticides, including through the mixtures with synthetic insecticides. This study aimed to investigate the toxicity of copaiba oil-resin mixtures (COR) with deltamethrin, beta-cyfluthrin, beta-cypermethrin, methomyl, triazophos and chlorpyrifos for S. frugiperda. Bioassays were performed in the laboratory using newly hatched caterpillars on a contaminated surface (filter paper). Initially, concentration-mortality curves were established for each insecticide and COR. Based on the results, experiments were conducted to verify the effect of the COR mixtures with synthetic insecticides in the proportions of 1:1 (LC 25 + LC 25 ) on larvae of S. frugiperda. Additionally, COR concentration-response curves were established by adding 1/8 of the recommended rate of each insecticide. Notably, the use of this concentration for all insecticides was previously determined in bioassays, and no significant toxicity was found for S. frugiperda caterpillars. It was found that the toxicity of COR increased substantially by adding synthetic insecticides, especially with lower mixtures with beta-cypermethrin, methomyl and triazophos.Keywords: Bioinsecticide.

POTENCIALIZAÇÃO DO ÓLEO-RESINA DE COPAÍBA COM INSETICIDAS SINTÉTICOS PARAO CONTROLE DA LAGARTA-DO-CARTUCHO RESUMO -O controle de Spodoptera frugiperda (J. E. SMITH) (Lepidoptera: Noctuidae) tem sido realizado principalmente com inseticidas piretróides e organofosforados. O uso contínuo e indiscriminados de inseticidas sintéticos, durante décadas, tem ocasionado a seleção de populações resistentes, bem como preocupações em relação à saúde humana e ao meio ambiente. Uma alternativa é o emprego de inseticidas botânicos, inclusive por meio de misturas com inseticidas sintéticos. Assim, este trabalho teve por objetivo investigar a toxicidade de misturas do óleo-resina de copaíba (ORC) com os inseticidas deltametrina, beta-ciflutrina, beta-cipermetrina, metomil, triazofós e clorpirifós para S. frugiperda. Foram realizados bioensaios em laboratório utilizando-se lagartas recém-eclodidas em superfície contaminada (papel filtro). Inicialmente, foram estabelecidas curvas de concentração-mortalidade para cada inseticida e para o COR. A partir dos resultados obtidos foram realizados bioensaios para verificar o efeito das misturas do ORC com os inseticidas sintéticos nas proporções de 1:1 (CL 25 + CL 25 ) sobre lagartas de S. frugiperda. Adicionalmente, foram estabelecidas curvas de concentração-resposta do ORC adicionando-se 1/8 da dose comercial de cada inseticida. Vale destacar que o uso desta fração para todos os inseticidas foi d...
