life cycle of the taiga tick Ixodes persulcatus in the dark taiga forests of the Eastern Sayan Plateau

The life cycle of Ixodes persulcatus was studied in natural taiga environments of the Eastern Sayan Plateau (the Kemchug Upland, 56°10’N, 91°30’E). Engorged larvae and nymphs can develop with or without morphogenetic diapause, the ratio of these two ways being 77.25 / 22.75% and 43.43 / 56.57% for l...

Description
Summary:The life cycle of Ixodes persulcatus was studied in natural taiga environments of the Eastern Sayan Plateau (the Kemchug Upland, 56°10’N, 91°30’E). Engorged larvae and nymphs can develop with or without morphogenetic diapause, the ratio of these two ways being 77.25 / 22.75% and 43.43 / 56.57% for larvae and nymphs, respectively. The hypothetical seasonal hemipopulation consists of 34.5 ± 4.5, 50.1 ± 1.3, 13.2 ± 4.0, and 2.2% of unfed adults completing the 3-year, 4-year, 5-year, and 6-year life cycle, respectively. The mean life span is 3.83 ± 0.10 years. The “life table” predicting the probability of survival to the adult stage was developed.
