3435 Asian Citrus Psyllid
State Interior Quarantine
 

A.    Pest.  A quarantine is established against the following pest, its hosts, and possible carriers:

 

(a) Asian Citrus Psyllid (Diaphorina citri).

 

B.    Area Under Quarantine.

 

(1) A county or portion thereof shall be included in an appropriate host nursery stock regional quarantine zone and bulk citrus regional quarantine zone when survey results indicate an infestation is present or not, and the Department has evaluated the county based on the pest risk factors in Subsection (b)(2), or the local California County Agricultural Commissioner(s) is notified and requests the county be included into a regional quarantine zone. The Department shall also issue electronic and/or written notification of the regional quarantine zone designation(s) to other California County Agricultural Commissioners and other interested or affected parties and post notification of the designation to its website at: https://www.cdfa.ca.gov/plant/acp/regulation.html.

 

The notification shall include a web link to a map of the host nursery stock regional quarantine zones and bulk citrus regional quarantine zones, a list of the counties or portions thereof in each regional quarantine zone, a written description of the Department’s evaluation of the pest risk factors associated with the county or portion thereof, and instructions on the process to appeal the designation of a county or portion thereof into a regional quarantine zone.  Automatic notifications of any changes in regional quarantine zone designations will be available through a list serve option. Any individual or local entity may appeal the designation of a county or portion thereof into a regional quarantine zone by submission to the Department of a written request for review of the designation accompanied by clear and convincing evidence justifying a change in the designation. The appeal must be filed no later than ten (10) working days following issuance of the notice of designation by the Department. The Department must respond with a written decision no later than ten (10) working days following receipt of the appeal. During the pending of the appeal, the designation under appeal shall remain in effect.

 

(2) A county or a portion thereof shall be included in a regional quarantine zone based upon a combination of the following pest risk factors:

 

                (A) The level of Asian citrus psyllid infestation

 

                                1. Generally Infested Regions are counties or parts of counties where multiple asian citrus psyllids are routinely detected throughout the area and during every survey period.

 

                                2. Partially Infested Regions are counties or parts of counties where asian citrus psyllids have been                                 detected, but are not routinely detected throughout the area or during every survey period

 

                                3. Uninfested Regions are counties or parts of counties where asian citrus psyllids have not been                                 detected

 

                (B) The presence of or proximity to Huanglongbing disease detections

 

                (C) The proximity to the United States/Mexico border

 

                (D) Geographical barriers to the natural movement of ACP, such as mountains or host-free areas

 

                (E) Contains a commercial citrus growing region

 

                (F) Whether sufficient citrus commodity cleaning and packing capacity is available to process the majority of citrus grown in a region, as determined by the Department in consultation with citrus industry experts knowledgeable in citrus variety, acreage increase or decrease trends, historical production volumes for different regions, and volume capability of cleaning and packing capacity in different regions.
