The increase in insect pests infesting and causing damage to this crop has also increased, generating economic impacts. Among these, the tan bug (Thaumastocoris peregrinus) deserves attention. This bug is a pest insect with a sucking food habit, which causes damage to eucalyptus leaves. New control methods have been studied and developed for this pest, such as biological control and control with the use of botanical insecticides. Thus, the objective of this work was to evaluate the insecticidal effect of the essential oils of Eugenia uniflora (0.75%), Pogostemon cablin (0.75%) and the entomopathogenic fungi Beauveria bassiana (1x108 conidia.mL-1) and Metarhizium anisopliae (1x108 conidia.mL-1) on T. peregrinus adults in the field. These treatments were sprayed on branches of Eucalyptus camaldulensis. Subsequently, 10 adult T. peregrinus insects were placed in contact with the branches, which were wrapped in bags made with voile-type fabric in order to prevent the insects present there from escaping, they remained in the field for seven days and were later collected, and transported to the Biological Control laboratory. Insect mortality was evaluated and stink bug feces, present on leaves, were counted. All treatments caused mortality in adults of T. peregrinus in the field, especially the essential oil of E. uniflora and the entomopathogenic fungus M. anisopliae, but essential oil of E. uniflora was the treatment that caused the highest mortality of insects, and which had the lowest number of feces found on the leaves. Since none of the treatments, with the exception of the control, were statistically different, it is considered that the treatments in which cherry and patchouli essential oil were used and those in which the fungi B. bassiana and M. anisopliae were used are forms of control with potential on T. peregrinus adults in the field. O gênero Eucalyptus, nativo da Austrália, foi introduzido no Brasil no século XX e juntamente com incentivos de produção, este se tornou uma das culturas mais produzidas de floresta plantada. O aumento de insetos-praga infestando e causando danos nesta cultura também aumentou, gerando impactos econômicos. Dentre estes, o percevejo-bronzeado (Thaumastocoris peregrinus), merece atenção. Este percevejo é um inseto-praga de hábito alimentar sugador, que causa danos nas folhas de eucalipto. Novos métodos de controle vêm sendo estudados e desenvolvidos para esta praga, como o controle biológico e o controle com o uso de inseticidas botânicos. Assim o objetivo deste trabalho foi avaliar o efeito inseticida dos óleos essenciais de Eugenia uniflora (0,75%) Pogostemon cablin (0,75%) e dos fungos entomopatogênicos Beauveria bassiana (1x108 conídios.mL-1) e Metarhizium anisopliae (1x108 conídios.mL-') sobre adultos de T. peregrinus em campo. Estes tratamentos foram pulverizados em ramos de Eucalyptus camaldulensis. Posteriormente, 10 insetos adultos de T. peregrinus foram colocados em contato com os ramos, estes envoltos em sacos confeccionados com tecido do tipo voil a fim de evitar a fuga dos insetos ali presentes, os mesmos permaneceram no campo durante sete dias e posteriormente foram coletados e transportados ao laboratório de Controle Biológico. A mortalidade dos insetos foi avaliada e as fezes dos percevejos, presentes nas folhas, foram contabilizadas. Todos os tratamentos, causaram mortalidade nos adultos de T. peregrinus em campo, com destaque para o óleo essencial de E. uniflora e o fungo entomopatogênico M. anisopliae, porém óleo essencial de E. uniflora foi o tratamento que causou a maior mortalidade dos insetos e que teve menor número de fezes encontradas nas folhas. Por nenhum dos tratamentos, com exceção da testemunha, se diferenciarem estatisticamente considera-se que os tratamentos em que foi utilizado o óleo essencial de pitanga e de patchouli e os que foi utilizado os fungos B. bassiana e M. anisopliae são formas de controle com potencial sobre os adultos de T. peregrinus a campo. 2022-08-29T18:46:15Z 2022-08-29T18:46:15Z 2022-06-10 bachelorThesis ALVES, Leonardo Tozzetti.
