Pest identification
and confirmation—Apple maggot
Apple maggot is native to the northeastern United States and Canada. It was not discovered attacking
apples until about 100 years after trees were introduced from Europe. It is now considered a major pest
of apples in several apple-growing regions because it directly damages the fruit. Apple maggot is closely
related to walnut husk fly and cherry fruit fly. It can be distinguished from these other pests by the
banding on its wings. It is established in Del Norte, Siskiyou, Humbolt,
Trinity, Shasta, and Sonoma counties in California. Please report sightings in other counties to your
county agricultural commissioners. |  |
