This monoculture is suitable for the appearance of pest insects, especially Thaumastocoris peregrinus, popularly known as bronze - bug. The insect sucks the sap from the leaves, which look silvery, later evolving into a tan and making them to fall. Several control methods have been tested, including chemical control, biological control and alternative control with natural products and plant extracts. Thus, the objective of this work was to evaluate the essential oils of citronella (Cymbopogon winterianus Jowitt), patchouli (Pogostemon cablin (Blanco) Benth.) and lavender (Lavandula angustifolia Mill.) on the longevity of T. peregrinus adults. Four treatments were placed: sterilized distilled water (control); citronella essential oil; patchouli essential oil and lavender essential oil, all at 1% concentration. For the bioassays, Eucalyptus dunni leaves were immersed in the corresponding solutions and after evaporation of water excess they were provided to groups of 10 insects and kept in gerbox boxes sealed with plastic film and conditioned in a heated chamber (26 ± 2 ° C, 14 h photophase and 70 ± 10% RH). Fifty insects were used for each treatment, each insect was considered a repetition. The evaluations were performed every 12 hours, over a total period of 120 hours. Following the same methodology, patchouli oil was applied at different concentrations (1.25%, 1%, 0.75%, 0.5% and 0.25%). To identify the compounds present in the oils, gas chromatography of the oils was performed. After 108 hours of application, the treatment of patchouli essential oil caused total mortality of adult T. peregrinus individuals, differing significantly from the control with 95.7% of live insects and other treatments, citronella 22.9% and lavender 25.7%, of live insects. In the application of patchouli oil at different concentrations, it was observed that after 120 hours the survival of 0%, 10%, 20% 34% and 54% of the adult insects at the concentrations of 1.25%, 1% 0.75%, 0.5% and 0.25% of patchouli oil, respectively, and 68% for control. Chromatography of the essential oils identified a total of 16 constituents for citronella (C. winterianus), citronellal, geraniol and limonene being the major compounds with 34.15%, 10.45% and 7.98%, respectively. Patchouli chromatography (P.cablin) identified a total of 12 compounds, where the patchouli alcohol, α-guaienum and y-patchoulene were the major constituents with 21.99%, 18.32% and 16.44%, respectively, respectively. In the lavender oil (L. angustifolia) of a total of 12 compounds, three were major: 1.8 cineol (43.73%), trans-verbenol (12.77%) and fenchona (11.71%). The products tested reduced the longevity of adults of T. peregrinus, presenting potential for future studies and to be tested in control programs. O Eucalyptus é o gênero que apresenta maior representatividade no setor florestal, com área plantada de 5.473.176 hectares. Esta monocultura favorece o aparecimento de insetos-praga, destacando-se Thaumastocoris peregrinus, popularmente conhecido como percevejo-bronzeado. O inseto suga a seiva das folhas, as quais ficam com aspecto prateado, posteriormente evoluindo para um bronzeado e ocasionando a queda das mesmas. Diversos métodos de controle vêm sendo testados, entre eles o controle químico, controle biológico e o controle alternativo com produtos naturais e extratos de plantas. Assim o objetivo deste trabalho foi avaliar os óleos essenciais de citronela (Cymbopogon winterianus Jowitt), patchouli (Pogostemon cablin (Blanco) Benth.) e lavanda (Lavandula angustifolia Mill.) sobre a longevidade de adultos de T. peregrinus. Foram utilizados quatro tratamentos, sendo eles: Água destilada esterilizada (testemunha); óleo essencial de citronela; óleo essencial de patchouli e óleo essencial de lavanda, todos na concentração de 1%. Para os bioensaios, folhas de Eucalyptus dunni foram banhadas nas soluções correspondentes e após a evaporação do excessode água foram fornecidas para grupos de 10 insetos e mantidas em caixas do tipo gerbox vedadas com plástico filme e acondicionadas em câmara climatizada (26 ± 2°C, 14 h de fotofase e U.R. de 70 ± 10%). Foram utilizados 50 insetos por tratamento, sendo cada inseto considerado uma repetição. As avaliações foram realizadas a cada 12 horas, em um período total de 120 horas. Seguindo a mesma metodologia, realizou-se a aplicação do óleo de patchouli em diferentes concentrações (1,25%, 1%, 0,75%, 0,5% e 0,25%). Para identificar os compostos presentes nos óleos, realizou-se a cromatografia gasosa dos mesmos. Após 108 horas da aplicação, o tratamento com a pulverização do óleo essencial de patchouli causou mortalidade total dos indivíduos adultos de T. peregrinus, diferindo significativamente da testemunha com 95,7% dos insetos vivos e dos demais tratamentos, citronela 22,9% e lavanda 25,7% dos insetos vivos. Na aplicação do óleo de patchouli, em diferentes concentrações, constatou-se que após 120 horas houve a sobrevivência de 0%, 10%, 20% 34% e 54% dos insetos adultos para as concentrações de 1,25%, 1%, 0,75%, 0,5% e 0,25% do óleo de patchouli, respectivamente, e de 68% para testemunha. A cromatografia dos óleos essenciais identificou um total de 16 constituintes para citronela (C. winterianus) sendo o citronelal, geraniol e o limoneno os compostos majoritários com 34,15%, 10,45% e 7,98%, respectivamente. A cromatografia do patchouli (P.cablin) indentificou um total de 12 compostos, onde o álcool de patchouli, α-guaieno e o y-patchouleno foram os constituintes majoritários com 21,99%, 18,32% e 16,44%, respectivamente. No óleo de lavanda de um total de 12 compostos, três foram majoritários: 1,8 cineol (43,73%), trans-verbenol (12,77%) e fenchona (11,71%). Os produtos testados reduziram a longevidade de adultos de T. peregrinus, apresentando potencial para serem utilizados em futuros estudos e serem testados em programas de controle. 2020-11-13T12:20:31Z 2020-11-13T12:20:31Z 2017-06-07 bachelorThesis DALLACORT, Sidinei.
