Temporal distribution of Ixodes ricinus, Dermacentor reticulatus and Haemaphysalis concinna in Hungary

Abstract

A survey was carried out over a 4-year period to describe the temporal distribution of three ‘anthropophilic’ tick species, Ixodes ricinus, Dermacentor reticulatus and Haemaphysalis concinna in Hungary. Altogether 4658 adult ticks belonging to the three species were collected from 1931 red foxes ( Vulpes vulpes) killed in an area of about 70,000 km 2 representing all major climatic areas of the country. The seasonal activity of the three species was different. I. ricinus ticks were most active between April and June with an activity peak in May. A less marked increase of activity was also observed in September and October. The highest activity of D. reticulatus ticks was seen between September and November with an activity peak in October, nevertheless, a marked increase of activity could also be observed in April. Small number of I. ricinus and D. reticulatus were collected in all other months. H. concinna ticks were active from May to July with an activity peak in June and completely disappeared between October and March. The temporal distribution of the three tick species might be used for predictions on the seasonality of tick-borne diseases in Hungary.
