Resumo: Several researches focusing the use of silicon in plants have demonstrated an increase of plant resistance to stress and pests. This work aims to determine the effect of silicon, applied as calcium silicate (CaSiO3) on mealybug probing behavior by using the technique of Electrical Penetration Graphs (EPG). The citrus mealybug, [Planococcus citri (Pseudococcidae)], and coffee plants cvs. Catuaí and Catucaí were used in these experiments with silicate applied in plant pots at rate of 1 g of calcium silicate/250 g of soil/pot. The mealybug probing behavior showed that on treated plants, the mealybugs reached the phloem vessels, their feeding site, at similar time than untreated plants, demonstrating absence of mechanical barrier to stylet penetration after silicate application. In addition, other parameters associated with phloem and xylem phases were not significant, either comparing cultivars or silicate treatments. By consequence, calcium silicate applied in soil at these rates did not affect the citrus mealybug probing behavior in coffee plants.

Assim, foi estudado o efeito desse mineral no comportamento alimentar da cochonilhabranca [Planococcus citri (Pseudococcidae)] em cafeeiro, utilizando a técnica de monitoramento eletrônico (EPG). A fonte de silício foi o silicato de cálcio (CaSiO3) incorporado ao solo na dosagem de 1 g/250 g de solo/vaso, contendo plantas de Coffea arabica cvs. Catuaí e Catucaí e a testemunha (sem aplicação). O estudo do comportamento alimentar mostrou que, nas plantas crescidas em solo tratado com silicato de cálcio, as cochonilhas atingiram o floema, seu local de alimentação, em tempo similar ao verificado nas plantas não tratadas, demonstrando ausência de barreira mecânica por efeito da aplicação do silício. Nenhum parâmetro associado às fases floemáticas e xilemáticas apresentou diferenças, seja nas cultivares ou nos tratamentos com e sem silicato de cálcio. Dessa forma, o emprego do silicato, na dosagem avaliada, não afetou os parâmetros do comportamento alimentar estudado na cochonilha P. citri, em cafeeiro.Editora UFLA2014-03-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/526Coffee Science - ISSN 1984-3909; Vol. 9 No. 1 (2014); 10-13Coffee Science; Vol. 9 Núm. 1 (2014); 10-13Coffee Science; v. 9 n. 1 (2014); 10-131984-3909reponame:Coffee Science (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAporhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/526/pdf_55Copyright (c) 2014 Coffee Science - ISSN 1984-3909https://creativecommons.org/info:eu-repo/semantics/openAccessSanta-Cecília, Lenira Viana CostaPrado, ErnestoMorais, Jair Campos de2014-04-02T03:38:42Zoai:coffeescience.ufla.br:article/526Revistahttps://coffeescience.ufla.br/index.php/CoffeesciencePUBhttps://coffeescience.ufla.br/index.php/Coffeescience/oaicoffeescience@dag.ufla.br||coffeescience@dag.ufla.br|| alvaro-cozadi@hotmail.com1984-39091809-6875opendoar:2024-05-21T19:53:43.967233Coffee Science (Online) - Universidade Federal de Lavras (UFLA)true
