Ixodes persulcatus females were treated with Altozar and DDT at one of six consecutive time-points during the period beginning with attachment and ending with the commencement of oviposition. The moment of tick attachment (point 1) appeared to be the most sensitive time for the action of Altozar; a delay of detachment of some of the engorged females was observed, as well as a decrease in their mean weight and the non-detachment of a considerable number of the females over a long period. Similar effects were observed when Altozar was applied on the first and third days after attachment (points 2 and 3), although in the first case they were less pronounced. Altozar treatments on the fifth day of feeding, shortly before oviposition, and especially immediately after detachment (points 4, 5 and 6, respectively) mainly resulted in non-viability of the eggs. DDT was ineffective when it was applied at point 1. DDT treatments of ticks at points 3 and 5 were highly effective; this was expressed by a reduction in weight of the engorged females and a suppression of their fecundity at point 3, and death of all the larvae at different times after hatching at point 5. Many larvae also perished when the ticks were treated with DDT at point 6. Ticks were quite tolerant to DDT action when they were treated at points 2 and 4. The action of both compounds ultimately resulted in the inhibition of tick reproduction, but the rate and method depended on the compound applied as well as on the time of treatment. Altozar effects after treatment at points 1-3 may be considered to be hormonal.
全沟硬蜱雌蜱在从附着开始至产卵开始的这段时间内的六个连续时间点之一，用阿托扎尔和滴滴涕进行处理。蜱附着的时刻（第1点）似乎是阿托扎尔作用最敏感的时间；观察到一些饱血雌蜱的脱落延迟，以及它们平均体重的下降和相当数量的雌蜱在很长一段时间内不脱落。当在附着后的第一天和第三天（第2点和第3点）施用阿托扎尔时，也观察到了类似的效果，尽管在第一种情况下效果不太明显。在进食第五天、产卵前不久尤其是刚脱落后（分别为第4点、第5点和第6点）进行阿托扎尔处理，主要导致卵无法存活。在第1点施用滴滴涕时无效。在第3点和第5点对蜱进行滴滴涕处理非常有效；这表现为在第3点饱血雌蜱体重减轻和繁殖力受到抑制，以及在第5点孵化后的不同时间所有幼虫死亡。在第6点用滴滴涕处理蜱时，许多幼虫也死亡。在第2点和第4点处理蜱时，蜱对滴滴涕的作用相当耐受。两种化合物的作用最终都导致蜱繁殖受到抑制，但速率和方式取决于所施用的化合物以及处理时间。在第1 - 3点处理后阿托扎尔的作用可能被认为是激素性的。
