[The morphogenic diapause of the taiga tick and the methods for its quantitative assessment in a field experiment].
Methods of quantitative estimation of critical photoperiod and critical date of entering the diapause in ixodids have been worked out. S-shaped dependence of the number of diapausing larvae and nymphs of Ixodes persulcatus on their feeding periods has been shown. It has been established that in Central Udmurtia the average critical date of entering the diapause in 50% of satiated larvae and nymphs falls at the 18th and 29th of June, respectively, with the light day length of 17 hr 10 min and 16 hr 22 min.
