To the study of ixodid ticks of the Bolshesosnovsky municipal district of the Perm krai

This article presents the results of studying the abundance, biotopic location and seasonal dynamics of ixodid ticks Dermacentor reticulatus Fabricius, 1794 and Ixodes persulcatus (Schulze, 1930) on the territory of the Bolshesosnovsky municipal District located in the south-west of Perm Krai. An analysis of the biotopic abundance of ticks showed that I. persulcatus prefers various types of forests (relative abundance per season ranged from 20 to 104 specimens/flago-km), and D. reticulatus prefers meadow stations (relative abundance per season ranged from 39 to 830 specimens/flago-km). Assessment of the influence of temperature and humidity on tick activity has shown that for each factor in all biotopes and for each species there is a moderate or noticeable correlation of environmental parameters with changes in tick activity. The analysis of the seasonal dynamics of the activity of the studied species revealed the following: in May or early June, on average, there is a high number of adult ticks of both species, in midsummer their activity drops to zero and only in D. reticulatus activity resumes in late summer and early autumn and becomes even higher than in spring.
