The CRB/Industry has invested heavily in UC citrus programs, now threatened by HLB. Without technologies to eliminate HLB, it is critical to detect/remove HLB trees to eliminate inoculum. In 2019, surveys of ACP‐infested UCR (8% canine alerts) and uninfested LREC (0% alerts) validated EDTs including canine alerts. Future research will include: expanded surveys of citrus at UCR desert station; determine accuracy of canine detections where bactericides are used; if canines alert to infected leaf litter (explain alerts of adjacent trees); train canines for high beds, mulches, desert, etc. As EDTs evolve and we refine the use of the canines, this project will develop a systems approach including rapid subsampling on “suspect” trees using several methods with subsequent follow up via APHIS protocol and other primers.
