The California Department of Food and Agriculture (CDFA) has officially lifted the quarantine on the Queensland fruit fly (QFF) in Ventura and Los Angeles County, effective July 29, 2024. 

The Queensland fruit fly, first detected in California in San Diego County in 1985, was later identified in Orange County in 1991. This removal of the quarantine represents a major achievement in controlling this invasive pest. 

Counties currently impacted by invasive fruit fly quarantines:

• Oriental fruit fly: Riverside and San Bernardino Counties 
• Mediterranean fruit fly: Los Angeles County
