VENTURA (AP) — California agriculture officials have expanded their quarantine area for the Asian citrus psyllid after the two of the insects were found in Ventura County.

The Department of Food and Agriculture announced Friday that all of Ventura County and some 312 square miles of adjacent Santa Barbara County were being put under quarantine to minimize the spread of the pest, which can carry a disease fatal to lemon and orange trees.
