California officials continue so increase the quarantine zone for the Asian citrus psyllid in Tulare County as more finds are reported.

The latest move brings to 870 the number of square miles under regulatory quarantine in the major citrus-producing county.

Tulare County’s ACP quarantine has grown ever since officials first discovered the pest in the county in 2012. With one exception, the psyllid discoveries were made during normal trap inspections, and have typically been one or two finds at a time.

One continuous quarantine zone encompasses the eastern edge of the valley floor in Tulare County, and includes the entire communities of Terra Bella, Porterville, Lindsay, Farmersville, Ivanhoe, Orosi, and Dinuba.

All of Orange Cove and about half of Reedley in Fresno County are also under quarantine. Check out the quarantine map.

Also, a single ACP was detected west of Exeter near the community of Farmersville recently and may lead to another quarantine expansion later this month. The parameters and size of that additional new regulated area are being determined.
