a Density of nymphs infected with B. afzelii (DIN B. afzelii) in 2014 and 2015 in all three treatments in comparison to 2013 (baseline year). b Differences in DIN B. afzelii between the treatments in two separate years calculated with the Wilcoxon test with a correction for a baseline year (2013). The overall differences between the treatments were not significant either in 2014, or 2015 (P = 0.69 and P = 0.53, respectively)
