Fig. 5

Correlation between maximal temperature (5-days moving average, a) or 2-days moving average of saturation deficit (b) and questing nymph density. Arbitrary thresholds are shown in red and indicate limits above which nymphs are scarcely found to be in their rising phase. Green squares represent the samplings done in the rising (pre-peak) phase (from 1st of January to PND1), orange squares represent the rest of the samplings (post-peak phase)
