Abstract

Esta nota tem por objetivo relatar o ataque de larvas do coró-das-pastagens, Diloboderus abderus Sturm, 1826 (Coleoptera: Melolonthidae), em mudas de eucalipto híbrido (Eucalyptus grandis x Eucalyptus urophylla), na fazenda Bazana, município de Manoel Viana, Rio Grande do Sul. Essa praga se alimentou da casca das plantas na região do coleto, provocando “anelamento” das mudas. A mortalidade de mudas foi de 30% em 40ha. Este é o primeiro registro dos danos desse inseto em plantas de eucalipto no Brasil.This article aims to report the attack of larvae Diloboderus abderus Sturm, 1826 (Coleoptera: Melolonthidae) on seedlings of Eucalyptus hybrid ( Eucalyptus grandis x Eucalyptus urophylla), on the farm Bazana, in Manoel Viana, state of Rio Grande do Sul, Brazil. This pest consumed the bark of the ground, which caused the 'girdling' of seedlings. The mortality rate was 30%, in 40ha. No previous report was found in the literature regarding the occurrence of damages of Diloboderus abderus on Eucalyptus; thus, this is the first record of the pest on Eucalyptus in Brazil.
