ABSTRACT

Neste artigo é descrita ocorrência e o dano causado pelo ácaro vermelho europeu Panonychus ulmi (Koch) associado à cultura da videira. As coletas foram realizadas na safra 2005-2006 em Vitis vinifera L. da cultivar Merlot, nos municípios de Bento Gonçalves e Candiota, no Estado do Rio Grande do Sul, Brasil. As folhas infestadas apresentaram bronzeamento, com manchas avermelhadas na face adaxial, resultando na queda prematura das mesmas. Esse é o primeiro registro do ácaro vermelho europeu danificando a cultura da videira no Rio Grande do Sul.
