An Asian citrus psyllid (ACP) sample that was Candidatus Liberibacter asiaticus (CLas)-positive has been collected from a residential property in Ventura County in the Santa Paula area. The positive sample – comprised of 12 adult psyllids from a residential citrus tree in the Southwest area of Santa Paula – was collected on September 6 as part of the Multi-Pest Risk Survey and confirmed positive for CLas on September 19. This is the first confirmed CLas-positive ACP found in Ventura County.

While the first confirmation of a CLas-positive ACP in Ventura County is concerning, as of today, HLB has not been detected in any Ventura County citrus trees. However, it is more crucial than ever that populations of the ACP continue to be controlled properly in order to stop the disease from spreading.
