Go for the Smell

Oct 25, 2021

It turns out, specially trained dogs can find citrus trees infested with Asian Citrus Psyllid (ACP).  Canine Detection Services in Fresno has a grant from USDA to provide dogs that will sniff out the insects.  The grant runs until March 2022.

The dogs are trained to sniff out ACP using training aids which contain ACP scent which does not have the bacterium causing the disease. The dogs run a pattern within an orchard or along the perimeter of the orchard. Dogs will sniff all sides of the trees in a given pattern. Depending on the environmental conditions, the dogs can smell the psyllid within 22 feet of an infested tree.

Canine Detection Services is also working with CDFA inspectors in residential neighborhoods, according to Victoria Hornbaker, director of the Citrus Pest and Disease Prevention Division within the CDFA. In this instance, the dog handlers shadow CDFA inspectors as they survey residential citrus trees for the pest and disease.

Hornbaker says the dogs can be a valuable tool for state inspectors to survey neighborhoods more quickly. If a dog alerts on a tree, inspectors can investigate for ACP adults or nymphs, and collect insect samples. This is also done in conjunction with surveys for the HLB disease.

The dog team services are free to commercial growers in California, Arizona, and Texas through next March, according to Finke. To schedule a visit or for answers to specific questions, contact Lisa Finke by email at lisa@canine-detection.com.
