“…In our study, 32 compounds were identified by GC-MS analysis, which is higher than other studies, such as Goldbeck et al (2014), Bonora (2016), Araújo et al (2010), and Pereira (2010, who identified 21, 17, 10 and 10 compounds, respectively. This variation in the identification between the studies is due to the differences in the extraction methodology as well as in the plants used in the analysis because according to Darrow & Bowers (1997), despite the existence of genetic control, the variations of season, day, intra-plant, inter-plant, and intraspecific can influence the total content and proportions of plant secondary metabolite compounds.…”

The evaluation of the direct effects of the relationship between plants and predators without considering the participation of herbivores can provide vital information for the study of ecological interactions and integrated pest management. In this context, the present work studied the behavioral responses of Chrysoperla externa (Neuroptera: Chrysopidae) larvae to the volatile organic compounds of young and mature, undamaged and damaged leaves of Eucalyptus urograndis (Myrtaceae), and investigate the chemical composition of leaf essential oils and their effects on the green lacewing. The responses of the C. externa larvae to the odors emitted by leaves were evaluated by an experimental behavior test using a Y-tube olfactometer. The essential oil was extracted by hydrodistillation of the young and mature leaves with and without damage. The larvae respond attractively to the volatiles emitted without the participation of herbivores, and it selected preferentially odors emitted by young leaves with simulated herbivory. The chemical composition was analyzed using gas chromatography coupled with mass spectrometry. This research identified 32 compounds; some of them had not been identified in other studies. Young leaves had a higher content of essential oil compared to mature leaves. Among the compounds identified, eucalyptol, α-Terpineol, Aromadendrene, and α-Terpinyl acetate are the major compounds. An inversion in the content of eucalyptol (which decreases) and α-terpinyl acetate (which increases) is observed when young and mature leaves are damage. Thus, this work contributed with basic data on the potential use of eucalyptus forests as maintainers of natural chrysopids populations.

“…The Eucalyptus corresponds to one of the principal genera of the Myrtaceae family, native to Australia and cultivated worldwide [17,41,42,43,44]. Eucalyptus trees have perennial leaves that are odorous because of the presence of EOs that are produced and stored in secretory cells.…”

“…Eucalyptus trees have perennial leaves that are odorous because of the presence of EOs that are produced and stored in secretory cells. These EOs are aromatic, spicy, and colorless or pale yellow, although there are studies that have reported the color as being brownish or greenish [44].…”

Chemical Variability and Biological Activities of Eucalyptus spp. Essential Oils

Many plant species produce mixtures of odorous and volatile compounds known as essential oils (EOs). These mixtures play important roles in Nature and have been utilized by mankind for different purposes, such as pharmaceuticals, agrochemicals, aromatherapy, and food flavorants. There are more than 3000 EOs reported in the literature, with approximately 300 in commercial use, including the EOs from Eucalyptus species. Most EOs from Eucalyptus species are rich in monoterpenes and many have found applications in pharmaceuticals, agrochemicals, food flavorants, and perfumes. Such applications are related to their diverse biological and organoleptic properties. In this study, we review the latest information concerning the chemical composition and biological activities of EOs from different species of Eucalyptus. Among the 900 species and subspecies of the Eucalyptus genus, we examined 68 species. The studies associated with these species were conducted in 27 countries. We have focused on the antimicrobial, acaricidal, insecticidal and herbicidal activities, hoping that such information will contribute to the development of research in this field. It is also intended that the information described in this study can be useful in the rationalization of the use of Eucalyptus EOs as components for pharmaceutical and agrochemical applications as well as food preservatives and flavorants.

“…Os autores afirmam que é necessária uma atenção para a serapilheira, material gerado pelo cultivo em grande escala do eucalipto, a fim de evitar maiores consequências ao meio ambiente, em especial aos ecossistemas aquáticos, por conter grande quantidade de óleos nesse material (ARAÚJO et al, 2010).…”

O eucalipto, planta originária da Austrália, chegou ao Brasil, adaptou-se as condições climáticas e o solo, fatores estes altamente favoráveis para o seu desenvolvimento. Desta maneira, ao longo do tempo o eucalipto se propagou aos diversos estados brasileiros e a sua utilização passou a ser comercializada devido à rápida produção de sua madeira, o que agrega alto valor econômico. O presente artigo apresenta questões relativas aos impactos ambientais gerados pela utilização do eucalipto: busca esclarecer através de uma análise crítica desta cultura, os pontos negativos e positivos da sua utilização, questões ambientais acerca do eucalipto quanto à água, o solo, a biodiversidade e a educação ambiental. As discussões são norteadas sobre o impacto ambiental no que se refere à utilização de plantas exóticas do gênero Eucaliptus, que causa um desequilíbrio ambiental significativo para uma determinada região. O eucalipto contém algumas substâncias nocivas ao meio ambiente, o qual pode sofrer algumas consequências nada confortáveis e quase imperceptíveis. Procurou-se mencionar alguns possíveis impactos, ambientais e socioeconômicos, provocados pelo cultivo da cultura do eucalipto, averiguando a análise do ponto de vista ambiental a respeito do plantio e os mais diversos usos do eucalipto.
