Researchers at Virginia Tech have demonstrated that dogs can effectively detect the invasive spotted lanternfly, offering a potential solution to manage this destructive pest.
Early detection of the spotted lanternfly is crucial, but locating its eggs can be quite challenging. This is where dogs, with their exceptional sense of smell, come into play.
A study conducted by researchers at Virginia Tech reveals that dogs may serve as a valuable ally in combating the rapid spread of the spotted lanternfly. For the first time, the research indicates that pet dogs can assist in identifying this invasive pest.
The spotted lanternfly feeds on various plants and excretes a sugary substance known as honeydew, which encourages mold growth. Due to their destructive nature, some states have initiated campaigns urging residents to stomp on these pests upon sight. However, experts emphasize that the key to controlling their population lies in eliminating their egg masses, which can be difficult to spot as they often resemble dried mud and blend into their surroundings.
“Dogs have one dominant sense. It’s their nose. We use our eyes. Dogs use their nose like their eyes,” said Katie Thomas, a participant in the study.
Thomas and her nine-year-old pit bull mix, Finch, took part in the research, aiming to utilize their years of recreational scent work. They underwent both indoor and outdoor tests, successfully identifying egg masses and receiving rewards when Finch made accurate detections.
“To be able to do things that we already do, that we are having a lot of fun with… train our dogs to sniff stuff, being able to apply that to something like a real problem that affects our community is really fulfilling,” Thomas expressed.
The spotted lanternfly, native to Asia, was first identified in the United States in Pennsylvania over a decade ago. Since then, it has spread to 19 states, according to the U.S. Department of Agriculture (USDA).
“They are everywhere, and we need to search out the eggs. The problem is it’s too late once we have the lanternfly,” noted Carolyn Shelburne, another study participant.
Shelburne and her nine-year-old border collie, Hermes, were among the first five K9-handler teams to successfully pass their field tests. In total, 182 volunteer teams from across the U.S. participated in the study.
During indoor tests, dogs correctly identified the scent of the lanternfly more than 80% of the time. In real-world outdoor tests, they achieved a success rate of over 60%, which surpasses the performance of most human searches.
“Hopefully, more people will see that you can train any dog to do this, and it gives you something fun to do with your dog,” Shelburne added.
Researchers are optimistic that this study marks the beginning of a new role for dogs in protecting local ecosystems. Even in regions where spotted lanternflies are not currently a problem, dogs could be trained to detect other invasive species.
This innovative approach not only highlights the capabilities of dogs but also underscores the importance of early intervention in managing invasive pests. As communities continue to grapple with the challenges posed by invasive species, the collaboration between humans and dogs may prove to be a vital strategy in safeguarding local environments.
According to Virginia Tech, the potential for dogs to assist in environmental protection efforts is vast, paving the way for more research and training initiatives in the future.
