Resumo: The occurrence of thiamethoxam in coffee leaves and fruits after a soil drench application of the insecticide was assessed. The experiment was carried out in a five-year-old coffee plantation, in which 0.6 g of Actara 250 WG® was applied per plant. Samples of fruits and leaves were collected 30, 60 and 90 days after application and their thiamethoxam content was assessed. Thiamethoxam residues in the grains and hulls of fruits collected 120 days following the application were also determined, after drying and processing of the fruits. Thiamethoxam contents in the samples were determined by high performance liquid chromatography. A bioassay was done in the laboratory to assess the efficiency of thiamethoxam in the control of the coffee berry borer (Hypothenemus hampei (Ferrari)) by feeding adult females treated or untreated fruits. The results showed that concentrations of the insecticide in the leaves and fruits were highest 30 days after application. The occurrence of thiamethoxam in the fruits provided a partial control of the coffee berry borer.

O experimento foi realizado em uma lavoura de cinco anos de idade, aplicando-se 0,6 g de Actara 250 WG® por planta. Amostras de frutos e folhas foram coletadas aos 30, 60 e 90 dias após aplicação e analisadas com relação ao teor de tiametoxam. Análises de grãos e cascas de frutos coletados aos 120 dias da aplicação, após secagem e beneficiamento dos mesmos também foram efetuadas. As quantificações do tiametoxam nas amostras foram feitas por cromatografia líquida de alta eficiência. Realizou-se também, em laboratório, um teste de eficiência do tiametoxam no controle da broca-do-café (Hypothenemus hampei (Ferrari)), colocando-se fêmeas adultas para se alimentar em frutos provenientes de plantas tratadas ou não com o inseticida. Os resultados indicaram que as concentrações do tiametoxam nas folhas e frutos foram mais altas aos 30 dias da aplicação. A ocorrência do tiametoxam nos frutos proporcionou um controle parcial da broca-do-café.Editora UFLA2011-04-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/343Coffee Science - ISSN 1984-3909; Vol. 5 No. 2 (2010); 148-153Coffee Science; Vol. 5 Núm. 2 (2010); 148-153Coffee Science; v. 5 n. 2 (2010); 148-1531984-3909reponame:Coffee Science (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAporhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/343/pdfCopyright (c) 2011 Coffee Science - ISSN 1984-3909https://creativecommons.org/info:eu-repo/semantics/openAccessZimermann Vilela Torres, Fabríciade Oliveira Rigitano, Renê LuísCastro Torres, Lucas2013-02-24T14:05:06Zoai:coffeescience.ufla.br:article/343Revistahttps://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:2024-05-21T19:53:38.191414Coffee Science (Online) - Universidade Federal de Lavras (UFLA)true
