Canines can detect trees infected with the bacterium that causes huanglongbing. University of California Science for Citrus Health. Available: https://ucanr.edu/sites/scienceforcitrushealth/Research_Snapshots/Gottwald/. Interpretive Summary: Dogs have been trained to detect HLB-infected trees [huaglongbing (HLB) is the most severe disease of citrus worldwide] with an accuracy of >95% in commercial citrus orchards and >92% in infected residential properties. Dogs can be used as an early detection method to detect the disease in new areas and for commercial and residential survey. Detection by dogs is consistently months to years earlier than all other detection methods (molecular, serological, chemical) currently known. When deployed in commercial and residential settings, detection was real time requiring about 1-2 seconds per tree and can survey a 10 acre orchard in 1-2 hours depending on the number of diseased trees. When linked with a rapid response, detection by dogs will be a powerful tool which will help minimize disease spread and optimize planting longevity.
