Nationwide Varroa Infestation Level (VIL) displayed by climate region per month and overall average on data of the current study (a) and the USDA-APHIS National Honey Bee Survey NHBS (b). (n) is the number of samples in each graph and statistical analysis. Error bars in the line graphs are the Standard Error (SE). The Kruskal–Wallis test was conducted at three levels of significance: p < 0.05*, p < 0.01**, p < 0.001***. Box plots with different alphabetic letters are statistically significant. Climate region abbreviations are given in Table 1.
