Figure 2. (a) The average number of honeybee visits to flowers
was correlated with greater V. ceranae prevalence in bumblebees
(p = 0.005), but not in honeybees (p = 0.58). (b) The average total
duration of time honeybees spent on flowers per visit did not correlate
with V. ceranae prevalence in honeybees (p = 0.40) or bumblebees
(p = 0.014). (c) The average duration of time honeybees spent per visit
interacting with pollen and nectar simultaneously correlated with
greater V. ceranae prevalence in bumblebees (p = 0.009), but notV. ceranae prevalence in honeybees (p = 0.12). The number and
duration of visits by honeybees were converted to their original scales
for figure clarity. Significant slopes are indicated by solid lines,
while insignificant slopes are indicated by dotted lines. Honeybee
visits (per 30 min) were evaluated based on a 0.05 alpha threshold,
while the visit duration (seconds/visit) were evaluated according to the
Bonferroni-corrected alpha threshold of 0.0125.
