Abstract: The strong correlation between environmental conditions and abundance and spatial spread of the tick
Ixodes ricinus is widely documented. I. ricinus is in Europe the main vector of the bacterium Borrelia
burgdorferi, the pathogen causing Lyme borreliosis (LB). Humidity in vegetated systems is a major factor in
tick ecology and its effects might translate into disease incidence in humans. Time series of two remotely
sensed indices with sensitivity to vegetation greenness and moisture were tested as explanatory variables
of LB incidence. Waveletbased
multiresolution analysis allowed the examination of these signals at
different temporal scales in study sites in Belgium, where increases in LB incidence were reported in
recent years. The analysis showed the potential of the tested indices for disease monitoring, the usefulness
of analyzing the signal in different time frames and the importance of local characteristics of the study
area for the selection of the vegetation index.
