      Grapevine

      Pattern of damage

      The economic relevance of the grapevine moth is related, to yield losses, which are most pronounced in spring due to damage to the inflorescences (fruitset), and to the infestation of grapes in the summer which leads to reduced quality of the must and wine due to the colonization of the wound sites by secondary pathogens such as Botrytis (bunch rot) (Picture 3).
