Ixodid Ticks (Parasitiformes: Ixodidae) from Small Mammals in Reforesting Boreal Habitats of the NorthernEuropean Russia

摘要

Abundance of 2 ixodid tick species, Ixodes (Exopa/piger) trianguliceps Birula, 1895 and Ixodes (Ixodes) persulcatus Schulze, 1930 was studied during 6 years, in 1998-2001 and 2003-2004, at a research station in Gomselga Village (central Karelia, Kondopoga District, 62°04'N, 33°55'E). New data on host species composition and ixodid tick abundance were obtained from 4 forest plots at different stages of reforestation (secondary succession) following felling that occurred 7-14, 12-19, 25-32, and 80-87years ago. Individuals of/, persulcatus predominated and constituted 73% of the total ticks collected. The occurrence rates of different developmental stages were shown to fluctuate in the course of reforestation both in /. trianguliceps (larvae, 2.8-5.3; nymphs, 1.5-2.2; adults, 0-0.09) and in /. persulcatus (larvae, 4.3-10.6; nymphs, 0.6^1.2).
