L. Bailey wrote in 2001:

> The severe, widely-publicised disease of bees, referred to as ‘the Isle of
Wight disease’ in Britain early in the last century when colonies were more
numerous than subsequently, was wrongly attributed to the mite, which causes
no overt symptoms. The disease was almost certainly caused by bee paralysis
virus, which does cause the symptoms and is independent of the mite, and
which is similarly associated with large densities of bee colonies.
