Experiments with nymphs of Ixodes persulcatus and Dermacentor marginatus have shown that the rate and degree of engorgement, dropping off from the mouse, metamorphosis longevity and weight of emerging imagoes change under plant odour influence. The influence of acetone extract vapours of pepper, poplar buds, linden and aspen was tested. Under the influence of the vapour, acting as an attractant for the adults, engorgement weight of their nymphs and the weight of imagoes emerging from them increased; attractants change the nymph-imago metamorphosis duration as well. Repellent acting odours, as a rule, produce an opposite reaction. The phenomenon of the inversion of the infected D. marginatus reaction to the odour is proved in nymphs. Attractant for naive adult ticks (poplar buds) increased the time of feeding and weight of nymphs in comparison with the control. Just the opposite: nymphs infected with tick-borne encephalitis (TBE) virus produce an opposite reaction--weight decrease under influence of poplar buds as the repellent. Importance of the above phenomena for the ticks distribution and TBE epizootiology is discussed.
用全沟硬蜱和边缘革蜱若虫进行的实验表明，在植物气味的影响下，饱食率、从鼠体掉落的情况、变态、寿命以及羽化后的成虫体重都会发生变化。测试了胡椒、杨树芽、椴树和白杨的丙酮提取物蒸气的影响。在作为成虫引诱剂的蒸气影响下，其若虫的饱食体重以及从中羽化出的成虫体重增加；引诱剂也会改变若虫到成虫的变态持续时间。通常，驱避作用的气味会产生相反的反应。在若虫中证实了感染的边缘革蜱对气味反应的反转现象。与对照相比，对未感染的成年蜱有引诱作用的物质（杨树芽）增加了若虫的取食时间和体重。恰恰相反：感染蜱传脑炎（TBE）病毒的若虫会产生相反的反应——在作为驱避剂的杨树芽影响下体重下降。讨论了上述现象对蜱分布和TBE动物流行病学的重要性。
