Subject: APHIS Establishes a Mexican Fruit Fly (Anastrepha ludens) Quarantine Area in Texas
 
To: State, Tribal, and Territory Agricultural Regulatory Officials

On January 26, 2026, the Animal and Plant Health Inspection Service (APHIS) and the Texas Department of Agriculture (TDA) established a Mexican fruit fly (Anastrepha ludens: Mexfly) quarantine in Granjeno, Hidalgo County, Texas, designated the Granjeno quarantine.

APHIS and TDA established the Granjeno quarantine in response to the detection on January 16 of a wild mated female Mexfly from a trap in a grapefruit tree in a commercial citrus grove in Granjeno. The quarantine encompasses approximately 50 square miles with 213 acres of commercial citrus.

APHIS is applying safeguarding measures and restrictions on the interstate movement of regulated articles to prevent the spread of Mexfly to non-infested areas of the United States, as well as to prevent the entry of these fruit flies into foreign trade. APHIS is working with TDA to eradicate the transient Mexfly population following program guidelines for survey, treatment, and regulatory actions

The APHIS Exotic Fruit Flies website contains descriptions and maps of all current Federal fruit fly quarantine areas. APHIS will publish a notice of this change in the Federal Register
