“…Thaumastocoris peregrinus is a pest insect with high reproductive capacity and it is characterized by its rapid infestation in commercial eucalypt plantations (JACOBS & NESSER, 2005;MACHADO et al, 2020). Due to its rapid growth the application of synthetic phytosanitary products (NOACK et al, 2009;MACHADO et al, 2016;WILCKEN et al, 2019), biological control (WILCKEN et al, 2010;MASCARIN et al, 2012;BARBOSA et al, 2017;LORENCETTI et al, 2018;SOLIMAN et al, 2019;WILCKEN et al, 2019), and the use of alternative products (LORENCETTI et al, 2015) have been investigated to control this species.…”

This study evaluated the essential oils of Melaleuca alternifolia, Casearia sylvestris and Eugenia uniflora as inducers of defense mechanisms in Eucalyptus benthamii seedlings. Four mL of each oil, with a concentration of 0.75% were sprayed in E. benthamii seedlings and two bioassays were performed, in the first, the essential oils were sprayed and after 30 days, sugars, proteins, peroxidases, phenylalanine ammonia (PAL), and phenols were evaluated and; in the second, seven days after the first analysis, the essential oils were again sprayed and after three days, the same variables were evaluated. The essential oils of M. alternifolia, C. sylvestris, and E. uniflora sprayed had no significant effects on E. benthamii seedlings after 30 days in terms of total sugars, proteins, peroxidase, PAL activity, and phenols. However, when M. alternifolia and E. uniflora essential oils were sprayed seven days after the first analysis with evaluation after 3 days, an increase in total sugars was observed. After these days, all essential oils promoted an increase in protein levels. The oils of E. uniflora and C. sylvestris also increased peroxidase levels. The PAL defense enzyme not showed increased when essential oils were used. The essential oils of M. alternifolia and C. sylvestris had potential as inducers of defense mechanisms on E. benthamii seedlings after 3 days of their application, what it demonstrated not be permanent.

“…Outro estudo testou a eficiência dos inseticidas imidacloprid (78,8 gha -1 ), tiametoxam (37,5 gha -1 ), lambda-cia-lotrina+tiametoxam (21,2+25,8 gha -1 ), lambda-cialotrina (24,9gha -1 ) no controle de T. peregrinus. Todos os produtos testados foram eficientes, atingindo de 90 a 100% de controle (Machado et al, 2016).…”

Manejo Integrado De Pragas Na Eucaliptocultura: Inseticidas E Parasitoides São Compatíveis?

2017

Com o aumento de área plantada existe uma maior demanda por agrotóxicos no setor florestal. Entretanto, o uso incorreto e indiscriminado destas substâncias tem levado à seleção de insetos resistentes, impactos indesejáveis ao ambiente, além de reduzir as populações de inimigos naturais. Nos últimos anos tem crescido o interesse por princípios ativos que apresentem menor risco, ou seja, inseticidas seletivos. Com o intuito de reduzir a utilização do controle químico minimizar os impactos negativos, sua associação com o controle biológico utilizando inimigos naturais, como os parasitoides, tem sido uma alternativa promissora. O objetivo desta revisão foi sistematizar as evidências científicas sobre a compatibilidade destes dois métodos de controle e analisar os impactos da aplicação de inseticidas em insetos não alvos, como os parasitoides de pragas presentes na eucaliptocultura. Dentre as classes de inseticidas utilizadas, os organofosforados, carbamatos e piretroides estão entre os mais nocivos às diversas espécies de parasitoides, principalmente Trichogramma sp. Os reguladores de crescimento, biológicos e os neonicotinoides são considerados mais seletivos quando comparados às demais classes.

“…This combination resulted in vigorous trees with the wood of greater density and with great resistance to cancer disease caused by the fungus Cryphonectria cubensis (Bruner) Hodges, 1980 (Diaporthales: Cryphonectriaceae) (Paludzyszyn-Filho et al 2004;Valeri et al 2001). However, several insects have adapted to Eucalyptus plantations, probably due to the similarity with other Brazilian native plants and homogeneity of the planting that is a constant source of food (Machado et al 2016;Queiroz et al 2014). The adaptation occurred for several insect herbivores species, such as leaf-cutting ants (Atta spp.…”

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.
