Host-seeking activity of ixodid ticks in relation to weather variables.
Journal of vector ecology : journal of the Society for Vector Ecology 2003;
28(
2):.
Ixodid ticks were monitored in a temperate deciduous broad-leaved forest in South Moravia (Czech Republic). Relative abundance of the ticks collected before noon (10.00-12.00 h) was compared to several weather variables (air and soil temperatures, relative humidity, precipitation, wind speed, and derived values) using the Pearson correlation coefficient. The tick numbers were found to be most closely related to the amplitude of the soil (-5 cm) temperature between 07 h and 14 h (TSamp, in Ixodes ricinus), and the soil temperature (TS) at noon (in Haemaphysalis concinna) or in the morning (Dermacentor reticulatus). While a growing amplitude in TSamp caused an increased host-seeking activity of I. ricinus and H. concinna, it suppressed the activity of D. reticulatus, a tick species mainly occurring in colder seasons of the year in Central Europe. The air temperature (TA) and relative humidity (RH) were also closely related to the tick activity, whereas rainfall and wind speed remained largely uncorrelated with the activity of the three tick species. Multiple linear regression on several variables (TSamp, TA, TS, TA-TS, RH) explained 48% of the variance in I. ricinus, 47% in H. concinna, and 38% in D. reticulatus. Predictive two-variable regression models of relative abundance in host-seeking ticks were based on morning temperature (TA or TS) and morning RH as the most important environmental factors: they explained 32% (I. ricinus), 39% (H. concinna), and 35% (D. reticulatus) of the variance.
