Effective June 29, the Animal and Plant Health Inspection Service (APHIS) established a Mexican fruit fly (Anastrepha ludens or Mexfly) quarantine in a residential area of San Ygnacio, Zapata County, Texas. APHIS is applying safeguarding measures and restrictions on the interstate movement or entry into foreign trade of regulated articles from this area.
We are taking this action because APHIS confirmed one Mexfly larva on June 29 in the San Ygnacio area of Texas. In cooperation with Texas Department of Agriculture (TDA), APHIS is responding to this confirmed detection with the establishment of a new quarantine area, which encompasses approximately 29 square miles of Zapata County. APHIS is working with TDA to respond to this detection 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.
