[Variability of the life cycle duration in the taiga tick from mixed coniferous-broad-leaved forests of the Udmurt Republic].
Seasonal cohorts of the unfed Ixodes persulcatus imago in the study area were found to consist of the ticks passed through three-, four-, and five-year life cycles, in the ratio 72.6, 26.4, and 2.0% respectively, on the base of mean long-term values. Such ratio is established if 91.7% of larvae and 79.9% of nymphs develop without diapause, while the rest of larvae and nymphs develop with diapause. Mean duration of the tick generation is 3.3 years, with the fluctuations in certain of the years within the limits of 3.15-3.36 years.
