(Dec. 7) Thirty-two counties in Texas have been quarantined by the Texas Department of Agriculture to prevent the spread of the Asian citrus psyllid, according to the San Antonio Business Journal.

The insect can transmit citrus greening, commissioner Todd Staples said, in the article.

The disease does not exist in Texas, but psyllids have been spotted in several South and East Texas counties. Citrus producers and sellers in the quarantine area must subject host plants to a special treatment.
