Background. High level of public morbidity caused by ixodic ticks is registered in Primorsky territory. Study objective is to assess the ticks’ aggression towards humans.
Methods. The ticks’ aggression towards humans was measured by comparison of species community structure when gathering imagos from plants to the banner, and from humans. During 2012 it was identified 2331 species gathered from plants, and 215 ticks gathered from humans.
Results. In natural biotopes of the southern Primorsky territory Ixodes persulcatus dominated, then there were following species in descending order were: Haemaphysalis соncinna, Dermacentor silvarum, H. japonica douglasi, I. pavlovskyi, I. nipponensis. When removed ticks from humans there were registered I. persulcatus more frequent, then in descending order – D. silvarum, H. japonica douglasi, I. pavlovskyi, H. соncinna, I. nipponensis.
Conclusions. The most aggressive towards humans are species related to Ixodes, then Dermacentor and Haemaphysalis. Regarding epidemiological significance I. persulcatus is the most dangerous, and H. соncinna is the least dangerous.
