State agriculture officials have confirmed the discovery of a single Asian citrus psyllid in an insect trap just south of Farmersville.
The psyllid poses a major threat to the San Joaquin Valley's $1.8 billion citrus industry because of its potential to carry a deadly plant disease known as citrus greening.
While Tulare County has trapped several insects over the past year, it has not discovered the disease.
Tulare County Deputy Agricultural Commissioner Gavin Iacono said the state will begin the process of placing additional traps in the area of the Farmersville find to determine if there are more psyllids.
