USDA. Agricultural Research Service.
Dogs specially trained by Agricultural Research Service (ARS) scientists have proven to be the most efficient way to detect huanglongbing—also known as citrus greening—according to a paper just published in the Proceedings of the National Academy of Sciences. Currently, the only solid hope of curtailing the spread of citrus greening is to eliminate trees with the disease as quickly as possible to prevent further spread. Early detection of the citrus greening pathogen is crucial because trees can be infected and act as a source to spread the disease months or years before showing symptoms that are detectable by the naked eye. ARS plant epidemiologist Timothy R. Gottwald with the U.S. Horticultural Research Laboratory in Fort Pierce, Florida, discovered that dogs can be trained to sniff out the presence of Candidatus Liberibacter asiaticus, the bacteria that causes citrus greening, with greater than 99 percent accuracy.

A unique program run by the Agricultural Research Service in Fort Pierce, FL, uses specially trained dogs to detect citrus greening in orchards. The canine-detection method has an accuracy rate of 99 percent.

Agricultural Research Service (ARS) researchers in Florida have developed “attract-and-kill” traps to control Asian citrus psyllids in the suburbs where citrus trees are popular landscape plantings.
Texas A&M University. AgriLife Extension Service.
USDA NIFA research investment in Texas A&M AgriLife leads to breakthrough in fighting agricultural plant diseases. Researchers have made a discovery that will help combat fastidious pathogens, which cost U.S. agriculture alone billions of dollars annually.
U.S. Department of Agriculture.
The U.S. Department of Agriculture's (USDA) National Institute of Food and Agriculture (NIFA) today announced four grants totaling more than $13.6 million to combat a scourge on the nation's citrus industry, citrus greening disease, aka Huanglongbing. The funding is made possible through NIFA's Specialty Crop Research Initiative (SCRI) Citrus Disease Research and Extension Program, authorized by the 2014 Farm Bill.
U.S. Department of Agriculture.
USDA established a unified emergency response framework to address Huanglongbing (HLB), a serious disease of citrus that affects several U.S. states and territories. This framework will allow USDA and its many partners to better coordinate HLB resources, share information and develop operational strategies to maximize effectiveness.

Federally Regulated
USDA. APHIS. Plant Protection and Quarantine.
Contains the legal description of current federal quarantine areas for several citrus pests and diseases. Users can search by state and pest to determine the quarantine area(s) by state. An interactive map of quarantine areas is also available.
USDA. APHIS. Plant Protection and Quarantine.
Contains the requirements for moving fruit, nursery stock, or other regulated articles for several citrus pests and diseases.

USDA. APHIS. Plant Protection and Quarantine.
A Federal Order is a legal document issued in response to an emergency when the Administrator of APHIS considers it necessary to take regulatory action to protect agriculture or prevent the entry and establishment into the United States of a pest or disease. Federal Orders are effective immediately and contain the specific regulatory requirements.
USDA. Animal and Plant Health Inspection Service.
See what states have a federal quarantine for any of the targeted Hungry Pests, and identify which pests or diseases are at greatest risk due to a suitable habitat. In addition to federal quarantines, state-level quarantines might apply see State Summaries of Plant Protection Laws and Regulations (National Plant Board).
