Goals / Objectives
  1. Train canines to detect exotic and emerging pathogens of concern to U.S. Agriculture including Citrus Huanglongbing (HLB), Plum Pox Virus (PPV), vegetable viruses, grapevine viruses and other disease pathogens as they emerge.
    1. Initial training and validation of 13-15 canines originating with USDA, APHIS will be conducted in an experimental greenhouse and small field plots (grids) using both artificially inoculated and naturally infected plants
    2. Trained detector dogs will be tested in commercial production fields, orchards, and vineyards.
    3. Trained detector dogs will be tested in commercial vegetable transplant production houses, and production nurseries.
Methods (unparsed)

The procedures for training, evaluating and deploying canine detector dogs for pathogen detection have been extensively detailed for other bacterial and viral pathogens. In brief, the initial training begins with a proprietary sensitization process. Canines are rewarded for alerting on the proper target by providing a few minutes of play with the handler. Dogs will be sensitized via a series of randomized (blind) diseased and non-diseased sources to ensure the canines are alerting correctly at a high degree of accuracy. Typically this is done in randomized field trials, recording environmental conditions during each trial, and re-randomizing between each validation. We plan to train multiple dogs to detect each target pathogen. Moreover, because the sensitivity and accuracy of detection across host species and cultivars may not be the same â¿¿ presumably because the volatile composition or concentration may differ â¿¿ advanced training will be conducted in both an experimental greenhouse, field plots, orchards and vineyards on a collection of infected and non-infected cultivars and species to ensure that the canines are responding to a broad array of host types. The initial imprinting is anticipated to take 4 months to complete. Once trained, dogs will be field-tested in commercial plantings. They will be tasked to locate infected plants within plantings of selected crops, and relative to vegetable viruses will be used to scout field perimeters to locate potential reservoir weed hosts.
