Asian citrus psyllids found in Fresno County

San Joaquin Valley

The California Department of Food and Agriculture’s Plant Pest Diagnostic Center (PPDC) has identified two Asian citrus psyllids (ACP) on a glassy-winged sharpshooter trap from a packinghouse in the Orange Cove area of Fresno County. This has been the first time that the ACP has been detected in Fresno County since November 2019.

Following confirmation of the ACP detections, agricultural staff from the Citrus Pest and Disease Prevention Division (CPDPD) began conducting a survey and subsequently collected additional suspect ACP adults and nymphs from trees on the packinghouse premises, which were sent to the PPDC for identification.

All residential properties with host plants within 400 meters of the detections in Fresno County will be treated to prevent ACP population spread. Any growers who are located within 800 meters of the detection site will be notified by the Fresno County Grower Liaison Teri Blaser.

Following an increase in recent ACP detections across the Central Valley, including in Tulare and Kern counties, growers, packers, haulers and all citrus industry members are encouraged to be extra vigilant in their ACP mitigation steps and adherence to regulatory practices.

Contact your regional grower liaison for the latest information on detections near you and coordinated or area-wide treatment schedules. Find your grower liaison here.
