Honeybee decline linked to deadly virus
A parasitic mite has helped a virus wipe out billions of honeybees across the globe, say scientists.
A team studying honeybees in Hawaii found that the Varroa mite helped spread a particularly nasty strain of a disease called deformed wing virus.
This has led to "one of the most widely-distributed and contagious insect viruses on the planet".
The findings are reported in the journal Science.
