Grapevine defoliation by Spodoptera frugiperda Smith, 1797 (Lepidoptera: Noctuidae) in Brazil.

The fall armyworm, Spodoptera frugiperda Smith, 1797 (Lepidoptera: Noctuidae), is a polyphagous pest that causes losses in several crops. The knowledge of host plants is essential for establishing management and control strategies. The present study reported the first occurrence of S. frugiperda in Brazilian grapevines. It is recommended that further studies should be carried out in the laboratory to understand the biological aspects of the damage to different structures (leaves and grapes). This information will be essential to assess the potential of S. frugiperda damage to vines. [ABSTRACT FROM AUTHOR]
