    Pest Profile

    • About the pest


      Late instar larvae are approximately 10 to 12mm long. The head and legs are dark brown to black. The body color varies from yellow and green to brown (Picture 1). The adult moth has a forewing that is yellow to orange with a well defined dark-brow to black patch on the mid-wing (Picture 2).

      Symptoms & Diagnosis

      Pattern of damage

      The vine moth causes economic damage through yield loss when the larvae feed on the inflorescenes reducing fruit set. Later infestations, during the summer, cause both direct damage to the fruit and secondary damage through disease pathogens such as Botrytus (bunch rot) colonising the damage tissue. This secondary damage reduces the quality of the grape juice (must).
