O sistema de defesa induzido das plantas é ativado após a ocorrência do dano provocado por um herbívoro. O objetivo deste trabalho foi avaliar se plantas de eucalipto (Eucalyptus grandis) atacadas previamente por lagartas de Thyrinteina arnobia tornam-se resistentes ao corte de operárias de Atta sexdens rubropilosa. Não houve diferença significativa no tempo gasto por operárias dessa formiga em iniciar o corte em plantas atacadas ou não. Porém, houve diferença significativa no tamanho de fragmentos cortados. Concluiu-se que plantas previamente atacadas tornam-se menos atrativas para A. sexdens rubropilosa devido à ativação do seu sistema de defesa induzido. The induced defense system of plants is activated after the occurrence of damage by a herbivore. The objective of this work was to evaluate whether plants of Eucalyptus grandis previously attacked by larvae of Thyrinteina arnobia become resistant to cutting by the leaf-cutting ant Atta sexdens rubropilosa. There was no significant difference in the lapse of time spent by the workers of this ant before they started cutting plants previously attacked or not. There was significant reduction in the size of leaf fragments cut by the ants. It was concluded that plants previously attacked were less attractive to the leaf cutter due to the activation of their induced defense system
