Resumo: | Oligonychus ilicis (McGregor, 1917) (Acari: Phytoseiidae) is considered one of the main phytophagous mites of coffee plants (Coffea spp.). Although not considered as principal, it was already referred as the second in importance for the Conillon coffee plant, Coffea canephora Pierre & Froehner. It is commonly in equilibrium, probably due to the presence of natural enemies, among them predatory mites belonging to the Phytoseiidae family. This work had as objectives to evaluate the O. ilicis population dynamics through the months of the year, the phytoseiids associated, and the spatial distribution of those mites in coffee plants. Studies were carried in a 1.3 ha coffee field located at EPAMIG, Lavras, Minas Gerais. Biweekly, ten leaves of superior, medium and inferior thirds (five leaves from each plant side) were randomly sampled from ten plants. The appraised leaves were removed from the third or fourth pair from the branch extremity. O. ilicis occurred along the whole period, being found in larger number of eggs than post-embryonic phases. Number of eggs in the medium and inferior parts of the plants was bigger than in the superior part. The periods of larger occurrence of O. ilicis coincided with the low pluvial precipitation time. Five species of predatory mites were found: Iphiseiodes zuluagai Denmark & Muma, 1972, Amblyseius herbicolus (Chant, 1959), Euseius citrifolius Denmark & Muma, 1970, Euseius concordis (Chant, 1959) and Euseius alatus DeLeon, 1966. The most abundant species was I. zuluagai, representing 72.4% of the phytoseiids collected and occurring during all the studied period. |

Oligonychus ilicis (McGregor, 1917) (Acari: Tetranychidae) é considerado um dos principais ácaros fitófagos do cafeeiro (Coffea spp.). Embora não seja considerado praga-chave, já foi referido como a segunda em importância para o Conillon, Coffea canephora Pierre & Froehner. Esse ácaro comumente encontra-se em equilíbrio, devido à presença de inimigos naturais, entre eles ácaros predadores pertencentes à família Phytoseiidae. Objetivou-se com este trabalho realizar o levantamento populacional de O. ilicis ao longo do ano, dos fitoseídeos a ele associados, bem como da distribuição espacial desses ácaros no cafeeiro. Os estudos foram conduzidos em cafezal de 1,3 ha, localizado na Epamig em Lavras, Minas Gerais. Foram amostradas quinzenalmente dez folhas dos terços superior, médio e inferior de dez plantas, aleatoriamente, sendo cinco de cada lado da planta. As folhas avaliadas foram retiradas do terceiro ou quarto par a partir da extremidade do ramo. O ácaro O. ilicis ocorreu ao longo de todo o período, sendo encontrado maior número de ovos que das fases pós-embrionárias. O número de ovos nas partes média e inferior das plantas foi maior em relação à parte superior. Os períodos de maior ocorrência de O. ilicis coincidiram com a época de precipitações pluviais baixas. Foram encontradas associadas a ele cinco espécies de ácaros predadores: Iphiseiodes zuluagai Denmark & Muma, 1972, Amblyseius herbicolus (Chant, 1959), Euseius citrifolius Denmark & Muma, 1970, Euseius concordis (Chant, 1959) e Euseius alatus DeLeon, 1966 (Acari: Phytoseiidae). O mais abundante foi I. zuluagai, representando 72,4% dos fitoseídeos coletados, ocorrendo durante todo período estudado.Editora UFLA2008-11-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/71Coffee Science - ISSN 1984-3909; Vol. 3 No. 1 (2008); 38-46Coffee Science; Vol. 3 Núm. 1 (2008); 38-46Coffee Science; v. 3 n. 1 (2008); 38-461984-3909reponame:Coffee Science (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAporenghttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/71/143https://coffeescience.ufla.br/index.php/Coffeescience/article/view/71/144Copyright (c) 2008 Coffee Science - ISSN 1984-3909https://creativecommons.org/info:eu-repo/semantics/openAccessFranco, Renato AndréReis, Paulo RebellesZacarias, Mauricio SergioAltoé, Bernardo FalquetoNeto, Marçal Pedro2013-02-23T12:46:52Zoai:coffeescience.ufla.br:article/71Revistahttps://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:2024-05-21T19:53:29.142710Coffee Science (Online) - Universidade Federal de Lavras (UFLA)true |
