San Luis Obispo County is stepping up efforts to trap and track a pest that threatens the area's multi-million dollar citrus industry.
Local officials made the move following the latest detection of an Asian citrus psyllid on an orchard in south county, near the Santa Barbara County line.
A new quarantine restricting the movement of citrus nursery stock and citrus fruit will be established by the California Department of Food and Agriculture.
This is the third detection in south county, including two in Arroyo Grande. The psyllid was also found last year in San Luis Obispo and Cayucos.
The pest spreads a disease called huanglongbing (HLB) or citrus greening. To date, only one infected tree has been found in California and that was in a Los Angeles County backyard in 2012.
