VENTURA COUNTY — A Candidatus Liberibacter asiaticus (CLas)-positive Asian citrus psyllid (ACP) sample has been collected from a residential property in Ventura County in the Santa Paula area and has been confirmed by the Citrus Research Board’s Jerry Dimitman Laboratory. The positive sample – comprised of 12 adult psyllids from a residential citrus tree in the Southwest area of Santa Paula – was collected on Sept. 6 as part of the Multi-Pest Risk Survey and confirmed positive for CLas on Sept. 19. This is the first confirmed CLas-positive ACP found in Ventura County.
An HLB quarantine zone will not be established as a result of this CLas-positive ACP detection and California Department of Food and Agriculture (CDFA) staff are swiftly conducting surveys and collecting samples from the property and all HLB host plants that are located within a 250-meter radius around the find, per the ACP/HLB Action Plan.
