- Аннотация: Abstract: Widely distributed Ixodes ricinus and Ixodes persulcatus ticks transmit many pathogens ofboth medical and veterinary significance. The ranges of these tick species overlap and form largesympatric areas in the East European Plain and Baltic countries. It has previously been shown thatcrossing I. ricinus and I. persulcatus is possible, resulting in the appearance of sterile hybrids. In thepresent study, we analyzed the features of this hybrid’s life cycle under laboratory conditions. For thispurpose, virgin females of I. ricinus and I. persulcatus ticks were obtained in the laboratory, and hybridgenerations of ticks were bred from the reciprocal crossings of these two tick species. According toour data, mating the females of I. ricinus and I. persulcatus with the males of another species leads to adecrease in the engorgement success of the females, a decrease in the number of hatched larvae, andthe appearance of a hybrid generation in which both females and males are sterile. Under laboratoryconditions at a constant room temperature and under natural daylight, the morphogenetic diapauseof the engorged I. persulcatus larvae began in September. For I. persulcatus nymphs, it occurred earlierthan for I. ricinus, in October and November, respectively. The hybrids generally repeated the featuresof the life cycle of the mother species.
