Ixodes ricinus horizontal movement within a humidity gradient and the influence of infection by Borrelia burgdorferi sensu lato (s.l.) on tick walking were investigated. Nymphs were placed within an arena containing a humidity gradient ranging from 45 to 95% relative humidity (RH). After 1 h of acclimation at 70% RHticks were released so that they could either stay, or walk...

Ixodes ricinus is known to display little resistance to desiccation. This tick is particularly exposed to desiccating conditions while questing for a host on the vegetation. Therefore, survival under hot and dry conditions in field-collected I. ricinus nymphs and adults was studied by exposing ticks to desiccating conditions created in the laboratory using saturated salt solutions...
