California and federal officials are lifting a grape pest quarantine in four counties.

The quarantine, designed to prevent the spread of European grapevine moth, expires on March 8 for Fresno, Mendocino, Merced and San Joaquin counties, according to a California Department of Food and Agriculture news release.

In addition, the U.S. Department of Agriculture has given $8 million to continue fighting the pests, which feed on several crops but primarily grapes.

The quarantine remains in effect for portions of Napa, Sonoma and Solano counties, where European grapevine moth was first found in California. More isolated infestations have led to smaller quarantines in Nevada, Santa Clara and Santa Cruz counties.
