Figure 2

Comparison of the incidence of different viruses in Apis mellifera carnica and Buckfast bees, together with 95% confidence limits based on fitted binomial mixed models (incidence over the sampling years 2012 and 2014 was averaged and bee breeder was included as a random factor, n= 78 samples). Accurate confidence limits could not be calculated for species with very low infection rates (≤5%), and are omitted from this graph. ***: significant difference with p < 0.01 (Wald tests, binomial GLMM).
