These moths usually have three generations per year. The larvae feed on flowers, buds, and mature fruit. Damage to fruit may also lead to secondary fungal infections. Hosts include plants from 27 different families, but only a few species within each family are at risk.
In Utah, potential hosts include grape, blackberry, cherry, and peach. In response to the threat posed by this invasive species, the Cooperative Agricultural Pest Survey (CAPS) has begun monitoring cherry and peach orchards in Northern Utah. Please be on the lookout, and if you believe you’ve found a European grapevine moth, contact Cory Vorel, USU CAPS Coordinator (firstname.lastname@example.org).
