Native to China and Korea, where the peach tree is also native,
the Oriental fruit moth was spread to many temperate fruit-growing areas of the
world during the first thirty years of this century. Today, the only commercial
peach-growing area of North America which is free of the pest is the province
of British Columbia.
The principal host is Prunus (peach,
nectarine, apricot, plum, cherry). In Ontario, apple (Malus) and pear (Pyrus) have
also be infested when they are grown in proxmity to peach orchards.
