Equipped with her own tailored bee suit and a hood to cover her floppy ears, Maple a former police dog " has an important retirement task: helping save thousands of honeybee hives. The canine has spent the past five months sniffing Michigan bee colonies for American foulbrood, a highly contagious bacteria that's fatal to the insects. Maple, an English springer spaniel, uses her extraordinary sense of smell as a "high-speed screening tool" to prevent beekeepers from having to manually inspect every hive. American foulbrood only becomes detectable to humans by smell when it reaches severe infection, at which point the colony risks death, said Meghan Milbrath, a researcher and assistant professor of entomology at Michigan State University. The ultimate goal is for Maple's work to serve as a blueprint for teaching canines to detect honeybee diseases. It's part of a larger bee conservation effort in a record-breaking year for colony death in the United States ... primarily driven by pesticides, pathogens, poor nutrition and pests. Although Maple's new "target odor" is distinct from her previous job ... the fundamentals remain the same. Handlers expose the canines to a scent, offer a reward and teach the dog to conduct an action that means they've found the odor they're looking for. In Maple's case, she sits when she detects the smell. [Handler, Sue] Stejskal said she has to train Maple to be familiar and comfortable with the new environment so the pup can focus on the target odor.
