Anastrepha ludens (Mexican Fruit Fly ): APHIS Establishes a Quarantine in Arroyo City, Cameron County, Texas

Country: United States

Title: Anastrepha ludens (Mexican Fruit Fly ): APHIS Establishes a Quarantine in Arroyo City, Cameron County, Texas

Richard Johnson, National Fruit Fly Policy Manager, at 301-851-2109.


Effective May 6, 2019, the Animal and Plant Health Inspection Service (APHIS) established a Mexican fruit fly (Anastrepha ludens or Mexfly) quarantine in Arroyo City, Cameron County, Texas. APHIS is applying safeguarding measures and restrictions on the interstate movement of regulated articles from this area.

On May 6, APHIS confirmed one mated female Mexfly in Arroyo City, Texas. As of May 8, APHIS had confirmed one additional Mexfly larva inside the quarantine. APHIS, in conjunction with the Texas Department of Agriculture (TDA), is responding to these confirmed detections with the establishment of a new quarantine area, which encompasses approximately 74 square miles of Arroyo City, Cameron County. There are 65 acres of commercial citrus within the quarantine area. APHIS is working with TDA to respond to these detections following program survey and treatment protocols. This action is necessary to prevent the spread of Mexfly to non-infested areas of the United States.

The establishment of this quarantine area is reflected on the following designated website, which contains a description of all the current federal fruit fly quarantine areas:

Under IPPC Standards, Anastrepha ludens is considered to be a pest that is transient, actionable, and under eradication in the United States.
