title: [Sensitivity of the females of Ixodes persulcatus and Dermacentor silvarum (Ixodidae) to baytex and the possibility of their overcoming poisoning with this substance].
abstract: Females of I. persulcatus and D. silvarum are very sensitive to baytex, the value of LD50 for both species are similar. The development of injury after exposure to baytex proceeds very quickly and the subsequent stages of injury development correspond to those caused by DDT (Uspensky and Levikov, 1974). The overcoming of baytex poisoning during the sucking of the host's blood is possible only at the initial stage of the injury. The simulatneous feeding on the same rabbit of ticks treated with baytex and control ones has shown a system effect of baytex on the second group of ticks.
