Asian Citrus Psyllid Detection in Sacramento Prompts New Quarantine

Sacramento County has been placed under quarantine following the detection of one Asian citrus psyllid in Sacramento’s Lemon Hill community. The entire county is now in Zone 7 of the ACP Regional Quarantine for Bulk Citrus Movement and Zone 2 of the ACP Regional Quarantine for Nursery Stock Movement.

The ACP regional quarantine model went into effect at the beginning of 2018 to better protect California’s commercial citrus from Huanglongbing.

In the ACP Bulk Citrus Regional Quarantine, Zone 7 compromises counties that:

• Are partially infested with ACP
• Have not had an HLB detection
• Are not a contiguous citrus growing region
• Are not proximate to the Mexico border

In the ACP Nursery Stock Regional Quarantine, Zone 2 compromises counties that:

• Are partially infested with ACP
• Have geographical boundaries between it and Zone 3
• Have not had an HLB detection
• Are not proximate to the Mexico border

The ACP was detected on a residential property in the Lemon Hill community of Sacramento. It is the first psyllid detection in Sacramento County. Agricultural officials have placed insect detection traps throughout the area to determine if this is a singular insect or one of a larger population. Residents with a citrus tree within 50 meters of the site where the psyllid was trapped will be contacted by agriculture officials who will ask to treat citrus host plants.
