Resumo: The coffee leaf-miner Leucoptera coffeella (Guérin-Mèneville, 1842) (Lepidoptera: Lyonetiidae) is the most important insect pest of coffee (Coffea arabica L.) in Brazil, where reductions in the production can reach 70 %. Application of the water dispersible (WB) granules formulation of the neonicotinoid insecticide thiamethoxam, via the irrigation water in drip irrigated coffee plantations is an alternative to the usual furrow application of granular formulations of insecticides for controlling this pest during the rainy season. In this work, the influence of application schedule of this insecticide, via irrigation water on the efficiency of coffee leaf miner control was investigated. The experiment consisted of four treatments: application of thiamethoxam 250 WG, via drip irrigation, in February (1), March (2) and April (3), and control (4). The percentage of mined leaves in selected branches was evaluated monthly and the concentration of insecticide in leaves determined from samples collected in August. Thiamethoxam was very efficient for the control of coffee leaf miner for all application times, with a protection period of about six months. There was an expressive loss of leaves in control due to pest attack which reduced production in approximately 58%.

Em lavouras irrigadas por gotejamento, o controle do bicho-mineiro com o inseticida neonicotinóide thiamethoxam formulado em grânulos dispersíveis em água (WG) e aplicado na água de irrigação, apresenta-se como uma alternativa ao controle químico convencional. Neste trabalho, investigou-se o efeito da época de aplicação do thiamethoxam via água de irrigação por gotejamento. O experimento consistiu de quatro tratamentos: thiamethoxam 250 WG aplicado via gotejamento em fevereiro (1), março (2), abril (3) e testemunha (4). A porcentagem de folhas minadas foi avaliada mensalmente e a concentração do inseticida nas folhas foi determinada em agosto. Nas três épocas em que foi aplicado, com ou sem infestação, o thiamethoxam 250 WG se apresentou altamente eficiente no controle do bicho-mineiro, num período de proteção de aproximadamente seis meses. As plantas do tratamento testemunha sofreram desfolha drástica como conseqüência do ataque da praga, apresentando uma redução na produção da ordem de 58%.Editora UFLA2007-12-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfapplication/pdfhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/31Coffee Science - ISSN 1984-3909; Vol. 1 No. 2 (2006); p. 150-155Coffee Science; Vol. 1 Núm. 2 (2006); p. 150-155Coffee Science; v. 1 n. 2 (2006); p. 150-1551984-3909reponame:Coffee Science (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAporengspahttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/31/27https://coffeescience.ufla.br/index.php/Coffeescience/article/view/31/108https://coffeescience.ufla.br/index.php/Coffeescience/article/view/31/109Copyright (c) 2007 Coffee Science - ISSN 1984-3909https://creativecommons.org/info:eu-repo/semantics/openAccessSouza, Júlio César deReis, Paulo RebellesRigitano, René Luis de OliveiraCiociola Júnior, Américo Iorio2013-02-23T12:27:38Zoai:coffeescience.ufla.br:article/31Revistahttps://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:2024-05-21T19:53:26.972012Coffee Science (Online) - Universidade Federal de Lavras (UFLA)true
