Widely distributed and ticks transmit many pathogens of both medical and veterinary significance. The ranges of these tick species overlap and form large sympatric areas in the East European Plain and Baltic countries. It has previously been shown that crossing and is possible, resulting in the appearance of sterile hybrids. In the present study, we analyzed the features of this hybrid's life cycle under laboratory conditions. For this purpose, virgin females of and ticks were obtained in the laboratory, and hybrid generations of ticks were bred from the reciprocal crossings of these two tick species. According to our data, mating the females of and with the males of another species leads to a decrease in the engorgement success of the females, a decrease in the number of hatched larvae, and the appearance of a hybrid generation in which both females and males are sterile. Under laboratory conditions at a constant room temperature and under natural daylight, the morphogenetic diapause of the engorged larvae began in September. For nymphs, it occurred earlier than for , in October and November, respectively. The hybrids generally repeated the features of the life cycle of the mother species.
蜱广泛分布，可传播许多具有医学和兽医学意义的病原体。这些蜱种的分布范围重叠，在东欧平原和波罗的海国家形成了大片同域分布区域。此前已有研究表明，[两种蜱的名称]杂交是可能的，会产生不育杂种。在本研究中，我们分析了这种杂种在实验室条件下的生命周期特征。为此，在实验室获得了[两种蜱的名称]的未交配雌蜱，并通过这两种蜱的正反交培育出了蜱的杂交后代。根据我们的数据，[两种蜱的名称]的雌蜱与另一种蜱的雄蜱交配会导致雌蜱饱血成功率降低、孵化出的幼虫数量减少，以及出现雌雄均不育的杂交后代。在实验室恒定室温及自然光照条件下，饱血的[一种蜱的名称]幼虫的形态发生滞育始于9月。对于[另一种蜱的名称]若虫，滞育分别在10月和11月开始，比[前一种蜱的名称]更早。杂种通常重复母本物种的生命周期特征。
