Abstract

Ixodes ricinus is the most common tick species in Europe and vector of many diseases of humans. The risk of contracting such a disease is influenced by many factors, but one of the crucial points is questing activity of unfed ticks. In order to supplement the few literature data on patterns of diel activity of this tick species and to examine the correlations between data on diel activity of ticks and their small mammal hosts and some meteorological variables, a survey was performed. Diel activity of questing I. ricinus and small rodents was studied in a known natural tick-borne encephalitis virus focus over 7 months at one sampling day monthly. 1,063 I. ricinus ticks and 25 rodents were sampled. Air temperature and humidity data were also recorded in the 24 study plots at time of sampling. From April to October questing activity of nymphs increased in the 3-h-period after sunrise, comparing to activity of the 3 h before sunrise. Proportion of nymphs sampled 3 h after sunset compared to total sampled nymphs 3 h before and 3 h after sunset showed correlation to activity of rodents. In the period of April-July both nymphs and larvae showed stronger activity from sunrise to sunset, this turned to dominant nighttime activity in August-September, whereas activity changed to equal in day and night in October. Our results indicate that natural light and rodent population have positive effect on questing activity of I. ricinus.
