Oriental Fruit Fly Treatments for the cities of Jurupa Valley and Riverside

Between November 12, 2024 and November 20, 2024 the California Department of Food and Agriculture (CDFA) confirmed that two oriental fruit flies (OFFs), Bactrocera dorsalis (Hendel) group, were trapped in the cities of Riverside and Jurupa Valley in Riverside County. Based on these detections, pest biology, information from the CDFA Bactrocera Science Advisory Panel (BacSAP), recommendations provided by the CDFA Primary State Entomologist, and the CDFA’s “Action Plan for Methyl Eugenol Attracted Fruit Flies including Oriental Fruit Fly Bactrocera dorsalis (Hendel),” the CDFA concludes that an infestation of OFF exists in the area. This pest presents a significant, clear, and imminent threat to the natural environment, agriculture and economy of California. Unless emergency action is taken, there is high potential for sudden future detections in Riverside County.
The detections of OFF described above require immediate action to address the imminent threat to California’s natural environment, agriculture and economy. More specifically, in addition to a wide variety of commercial crops, OFF threatens loss and damage to native wildlife, private and public property, and food supplies. Because the life cycle of the OFF detected on November 12, 2024 has not yet transpired, there is a high potential for sudden future detections in Jurupa Valley and Riverside. Therefore, the Secretary is invoking Public Resources Code Section 21080(b)(4) to carry out immediate emergency action to prevent the aforementioned loss and damage to California’s resources.
