European Grapevine Moth

Lobesia botrana, European grapevine moth (EGVM) was first reported in the United States from Napa County vineyards in October 2009, and was found in Nevada County in 2011 as part of the same infestation, resulting in a three year quarantine. 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 works with the USDA and the California Department of Food and Agriculture to trap and survey in the area in an attempt to detect additional European grapevine moths.  Red triangle traps are deployed annually March through October as part of our detection efforts.

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.
