A rare Cornish bee species could save dwindling populations from a disease that has wiped out millions of colonies worldwide, scientists have said.
New research suggests the Cornish Black honey bee is better at dealing with varroa mites, which carry a strain of a disease called deformed wing virus.
The virus has killed vast numbers of the world's bees.
