Among the main pests of cabbage, we can highlight the green aphid, which usually attacks young leaves causing weakening and leaf wilting. Pest control is commonly done through chemical methods, which can cause damage to the environment and humans, however, the search for alternative pest methods is essential. The use of essential oils for this control is a relevant strategy to consider, since oils are natural products extracted from plants and may have toxic activity and insect repellency. In this context, the experiments were carried out in the biological control laboratory and greenhouse of UTFPR campus Two neighbors, aiming to evaluate the toxicity of pitanga, patchouli and jasmine essential oils in green aphid. For the experiment, we used cabbage leaves approximately 40 days old, where they were submerged in the essential oil solutions of pitanga, patchouli, jasmine and the controls water, water + tween and untreated leaves, placed naturally to dry in a flow cabinet. . Subsequently, the leaves were wrapped with damp cotton and aluminum foil to retard leaf shriveling. Then they were placed in plastic Petri dishes and 10 second instar nymphs of Myzus persicae were added, taken in BOD (25 ° C ± 2 ° C and Photoperiod 12/12 hs). The experimental design was completely randomized with plots subdivided in time. We also compared the cumulative death averages of mortality by summing the mortality that occurred over the three days. All means passed the normality test, where they were considered normal and compared to the Tukey test at 5% probability. Insect mortality was evaluated during 24, 48 and 72 hours.

O repolho é uma hortaliça cultivada mundialmente e possui grande importância econômica para o Brasil, mas como qualquer outra cultura, possui insetos-praga que afetam negativamente a produção. Entre as principais pragas do repolho, podemos destacar o pulgão verde (Myzus persicae Sulzer, 1776), que geralmente ataca folhas jovens causando o enfraquecimento e murchamento foliar. O controle de pragas comumente é feito através de métodos químicos, que podem causar danos ao meio ambiente e ao homem, todavia, a busca por métodos alternativos para o controle de pragas é fundamental. O uso de óleos essenciais para esse controle é uma estratégia relevante, uma vez que os óleos são produtos naturais extraídos de plantas e podem possuir atividade tóxica e repelência aos insetos. Nesse contexto, os experimentos foram realizados no laboratório de controle biológico e casa de vegetação da UTFPR campus Dois vizinhos, com objetivo de avaliar a toxicidade dos óleos essenciais de pitanga, patchouli e jasmim em pulgão verde. Para a realização do experimento, foram utilizadas folhas de repolho com aproximadamente 40 dias, onde ficaram submersas nas soluções com diferentes concentrações de óleo essencial de pitanga, patchouli, jasmim e as testemunhas água, água + tween 80® e folhas sem tratamento, colocadas secar naturalmente em cabine de fluxo. Posteriormente, as folhas foram envoltas por algodão úmido e papel alumínio para retardar o murchamento foliar. Então foram colocadas em placas de Petri plásticas e adicionados 10 ninfas de segundo ínstar de Myzus persicae, levadas em BOD (25°C ± 2°C e Fotoperíodo 12/12 hs). O delineamento experimental foi inteiramente casualizado com parcelas subdivididas no tempo. Também foram comparadas as médias de mortalidade acumulada, somando a mortalidade ocorrida nos três dias. Todas as médias passaram por teste de normalidade, onde foram consideradas normais e comparadas ao teste de Tukey a 5% de probabilidade. A mortalidade dos insetos foi avaliada durante 24, 48 e 72 horas Os resultados desse trabalho demonstram potencial dos óleos essencial no controle do pulgão verde, necessitando novas pesquisas que possam considerar outras variáveis como estádio fenológico da cultura, condições em casa de vegetação e a campo, bem como formas de aplicação dos óleos e possíveis associações. 2020-11-13T13:07:52Z 2020-11-13T13:07:52Z 2019-12-03 bachelorThesis CASANOVA, Elana.

The cabbage is a vegetable grown worldwide and has great economic importance for Brazil, but like any other crop, has insect pests that negatively affect its production. Among the main pests of cabbage, we can highlight the green aphid, which usually attacks young leaves causing weakening and leaf wilting. Pest control is commonly done through chemical methods, which can cause damage to the environment and humans, however, the search for alternative pest methods is essential. The use of essential oils for this control is a relevant strategy to consider, since oils are natural products extracted from plants and may have toxic activity and insect repellency. In this context, the experiments were carried out in the biological control laboratory and greenhouse of UTFPR campus Two neighbors, aiming to evaluate the toxicity of pitanga, patchouli and jasmine essential oils in green aphid. For the experiment, we used cabbage leaves approximately 40 days old, where they were submerged in the essential oil solutions of pitanga, patchouli, jasmine and the controls water, water + tween and untreated leaves, placed naturally to dry in a flow cabinet. . Subsequently, the leaves were wrapped with damp cotton and aluminum foil to retard leaf shriveling. Then they were placed in plastic Petri dishes and 10 second instar nymphs of Myzus persicae were added, taken in BOD (25 ° C ± 2 ° C and Photoperiod 12/12 hs). The experimental design was completely randomized with plots subdivided in time. We also compared the cumulative death averages of mortality by summing the mortality that occurred over the three days. All means passed the normality test, where they were considered normal and compared to the Tukey test at 5% probability. Insect mortality was evaluated during 24, 48 and 72 hours. The results of this work demonstrate the potential of essential oils in the control of green aphid, requiring further research that may consider other variables such as crop phonological stage, greenhouse and field conditions, as well as ways of application of the oils and possible associations. |
