Although sunflower had nonsignificant effects on microparasites, We found
that increased sunflower pollen availability correlated with reduced Varroa
mite infestation in landscapes and pollen-supplemented colonies. At the
landscape level, each doubling of sunflower crop area was associated with a
28% reduction in mite infestation. In field trials, late-summer
supplementation of colonies with sunflower pollen reduced mite infestation
by 2.75-fold relative to artificial pollen.
