Distribution of hungry and engorged Ixodes persulcatus (Ixodidae) imagos on squares for absolute enumeration

: It was found out by the methods of large scale cartography and mathematics modelling, that the distribution of Ixodes persulcatus ticks around the point of clutch is still aggregated both on stages of hungry larvae and nymphs and on a stage of hungry imago. It is proposed to use the number of hungry imago aggregates as the criterium for the estimation of clatch number per square unit. Wild animals living in foothill taiga forests of the central part of Krasnoyarsk region support 9-10 female ticks per 10,000 square meters, and among them 5-6 females rise in full-bodied offspring, which completes the life cycle.
