Canines can detect trees infected with the bacterium that causes huanglongbing
Canines have a highly sensitive scent detection capability that is significantly better than most laboratory instruments and they can be trained to “alert” when they detect specific ‘smells’. Most people are familiar with their ability to detect bombs, drugs, and plant material at airports. However, canines are also used to detect human pests, such as bed bugs, and agricultural pests, such as stink bugs, date palm weevils and imported fire ants. Researchers have been training and evaluating the efficacy of canines for detecting CLas, the bacterium that causes huanglongbing (HLB). Researchers have demonstrated that well-trained canines can detect CLas over 95% of the time in commercial trees and over 92% of the time in residential trees.
