During two consecutive open seasons, i.e. in the fall of 1998 and the fall of 1999, a host specificity study was conducted in the vicinity of Mikolajki. Host specificity was assessed by calculating the prevalence and mean intensity indices of infection. The total of 87 game beasts were examined, including 53 deers, 18 wild boars, 15 roe deer and 1 elk. In(More)
The influence of day length and temperature on the activity of adult Dermacentor reticulatus was studied in two experiments. In the first one, changes in the activity of ticks kept in three aquariums were observed where the differentiating factor was day length (14, 15.5 and 17 h). In all of the three variants the activity of ticks decreased over time. The(More)
In the spring and fall of three consecutive years (1997, 1998 and 1999), a study of the seasonal activity patterns in hungry adult forms of Dermacentor reticulatus was conducted on experimental sites, supplemented by field observations beyond the sites in 2000 and 2001. The studies confirmed two periods of activity (spring and fall). The ticks' activity(More)
During the vegetation periods of five subsequent years, ie. 1997, 1998, 1999, 2000 and 2001, a field study aimed at defining, the current range of Dermacentor reticulatus in the so-called Mazuria focus was conducted on an area of about 24.000 km2 . The total of 68 sites covered by the study were located between the Great Mazurian Lakes District in the east(More)
Focus of Dermacentor reticulatus has been found on the area of fenced Cervides Farm. Very frequent occurrence of D. reticulatus on plants of red and fallow deer pens indicates that these animals in farm conditions are good hosts of adult forms of this tick. On pens of red deer the number of ticks caught on plants was considerable greater than on pens of(More)
