a Mean density of questing nymphs (DON) per 200 m2. Horizontal solid lines just above the x-axis depict months with average temperature below 7 °C. In winter 2012/2013, the number of months with the mean temperature below 7 °C was five, while in both 2013/2014 and 2014/2015 was four, however different months. b Density of nymphs (DON) in 2014 and 2015 in all three treatments in comparison to 2013 (baseline year). c Differences in DON 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 > 0.59 and P > 0.87, respectively)
