Lobesia botrana, European grapevine moth (EGVM) was first reported in the United States from Napa County vineyards in October 2009. Native to Southern Italy, it is now found throughout Europe, North and West Africa, the Middle East, and eastern Russia. The Nevada County Department of Agriculture is working with the U.SDA and the California Department of Food and Agriculture to trap and survey in the area in an attempt to detect additional European grapevine moths.
Studies of the European grapevine moth internationally show that larvae feed primarily on the flowers and fruit of the grape, and that they can also feed on a number of other hosts, including olives, cherries, nectarines, persimmons and pomegranates. The quarantine manual contains a complete list of alternative hosts.
