California agriculture officials are imposing a quarantine in part of Orange County after a bug capable of damaging the state's citrus industry was trapped there.
Officials say it's the Asian citrus psyllid's first migration out of the San Diego-Imperial counties quarantine zone.
Five adult psyllids were trapped on a backyard lemon tree in Santa Ana.
Tests are being conducted to determine whether they carried the huanglongbing disease, a bacteria that has caused billions of dollars of damage across Florida. Infected psyllids spread the tree-killing disease, calling "citrus greening," when they feed on leaves.
So far the only psyllid found infected with the bacteria was detected by a Fresno County sniff dog last month in a FedEx package shipped from India.
