The California Department of Food and Agriculture (CDFA) issued a medfly quarantine for the Central Los Angeles area after several pests were detected between March 3 and March 18. Detections were found in traps between March 3 and March 12 and in backyard fruit on March 18. The quarantine affects all growers, wholesalers, retailers and local residents in the 88-square mile quarantine zone near the University of Southern California.
The Medfly can infest more than 250 types of fruits and vegetables, causing severe impacts on California agricultural exports and backyard gardens alike.
Eradication efforts include the release of sterile male medflies into the area, the use of an organic formulation of Spinosad, originating from naturally-occurring bacteria to eliminate mated females and the removal of fruit within 100 yards of the larval detection property. CDFA is collaborating with the Los Angeles County Agriculture Commissioner and the United States Department of Agriculture (USDA) to contain and eradicate the medflies.
The eradication approach in the Los Angeles area is the standard Medfly program used by CDFA and it’s the safest, most effective and efficient response program available. CDFA has successfully eradicated each and every detected Medlfy infestation in California history, dating back more than 30 years.
