Right, here's from work done in Spain:

> The National Spanish Control Program for varroosis has enhanced Acarapis control through the regular application of miticides to honey bee colonies. Although no reliable studies of the efficacy of miticide treatment exist, it appears that these treatments are sufficiently effective to prevent clinical outbreaks, particularly since the prevalence we report never exceeds 30%, considered to be the level at which colony losses occur (Bailey, 1981).
