Influence of microclimate on the life cycle of the common tick Ixodes ricinus (L.) in thermophilic oak forest

Abstract

Under conditions of the South Moravian thermophilic oak forest (Valtice near Breclav), the life cycle of the common tick Ixodes ricinus was studied by continuous recording of main elements of microclimate (temperature and humidity) in three different biotopes: forest, margin of the forest and meadow. Simultaneously conditions and the process of tick hibernation were studied in four soil layers (surface, depths of 10, 20 and 30 cm). Observations made in the winter and vegetation periods were assessed by mathematical-statistical tests. Results obtained in the forest biotope and at its margin are presented in this paper; results from the meadow biotope will be published separately.
