The author passes in review the literature of the problem and states that according to it there has been registered up to now only one centre of the Dermacentor reticulatus tick within the present boundaries of Poland (Obitz). Then he quotes results of own investigations carried out in the elk preserve Czerwone Bagno (Province of Białystok), during which he found Dermacentor pictus on animals living in natural conditions (elk- Alces alces, roe- dear Capreotus cripreolus), on domestic animals (cattle) and on vegetation. Analysing the results of his investigations the author comes to the conclusion that D. pictius is a species well spread in the Czerwone Bagno preserve. Thiking in consideration till, role of D. pictus as a carrier of many a dangerous discase of men and animals, the author emphasizes the necessity of minute field investigations in the cited area.
