Trained Dogs Aid in Spotted Lanternfly Detection

The spotted lanternfly is an invasive, destructive insect found in 18 states that feeds on and can kill grapes, apples, hops, and maple and walnut trees. A study in New York, led by Cornell University, tested how trained dogs would do at detecting overwintering egg masses in vineyards and adjacent forested areas. The researchers found that humans were able to detect more egg masses in the vineyard environment, through systematic visual scans of vines and support poles. However, dogs detected more egg masses in the complex, forested areas adjacent to vineyards. In addition, the dogs were able to detect the spotted lanternfly infestations in areas where they had a low density, and where searching visually would be difficult and time consuming. The researchers believe dogs could help with early detection of the pest, in order to prevent it from becoming established in new areas.
