Dogs Become Heroes in Lanternfly Battle: Citizen Science Success!

Quick Smiles:

• Dogs are being trained to sniff out the elusive spotted lanternfly egg masses.
• Citizen scientists and their canine companions are stepping up to protect agriculture.
• An innovative study shows promising results in combating invasive species.

In a delightful twist of events, our furry friends are proving to be unexpected heroes in the fight against the invasive spotted lanternfly. A recent trial has demonstrated that ordinary dogs, alongside their owners, can play a crucial role in preventing this pest from wreaking havoc on local crops.

Originating from Asia, the spotted lanternfly was first detected in Pennsylvania back in 2014. Since then, it has spread rapidly across 18 states, hitching rides on trees, stone, lumber, and even vehicles.

The key to controlling this pest lies in spotting its egg masses early on. However, locating these eggs is no small feat.

“They often resemble mud smears or lichens and are tucked into bark crevices, cracks, or hidden undersides,” explained a plant pathologist involved in the study.

Dogs, with their exceptionally keen sense of smell, can be trained to detect these egg masses without disturbing their surroundings.

Professional conservation detection dogs have been successful in this task, but they are costly and not numerous enough to tackle the growing threat. Enter Sally Dickinson, the lead author of the study, who saw an opportunity to enlist the help of citizen scientists.

“With proper training, dog owners can turn their pets into powerful partners for conservation,” Dickinson noted.

The study involved 182 human-dog teams from across the United States. These teams were provided with devitalized lanternfly egg masses to use as training aids. Training took place either at home or in small groups under the supervision of a local trainer.

After months of preparation, the dogs faced two tests: an indoor odor recognition test and an outdoor field test. In the indoor setting, dogs had to identify the correct box containing the egg mass among several options.

Those that succeeded moved on to the outdoor test, where they had to locate the scent amidst other competing smells.

The results were impressive. In the controlled environment, dogs correctly identified the egg masses 82% of the time. In real-world conditions, they succeeded 61% of the time, outperforming human-only searches.

Of the dogs that passed both tests, 92% were able to find live egg masses with minimal additional training.

“These teams demonstrated that citizen scientists and their dogs can play a meaningful role in protecting agriculture and the environment from invasive species,” said Dickinson.

The spotted lanternfly poses a significant threat to vineyards, orchards, and other agricultural areas. Any effort to curb their spread is invaluable, and if it means taking your dog for a sniffing adventure in the park, it could be the difference between a farmer’s profit or loss this season.

This brilliant citizen science initiative is a testament to the incredible bond between humans and dogs and their shared ability to make a positive impact.
