The susceptibility of the taiga tick Ixodes persulcatus Schulze to 15 pyrethroids has been evaluated. The knockdown time after exposure of ticks to pyrethroids tested was quite similar. It was revealed that the lethal doses of type I pyrethroids (permethrin-like) induced the rapid attachment of ticks to host. In contrast, the fatal poisoning with type II pyrethroids (alpha-CN-pyrethroids) made the ticks unable to attach completely. Possible mechanisms of the acceleration and the prevention of attachment are discussed.
已评估了全沟硬蜱(Ixodes persulcatus Schulze)对15种拟除虫菊酯的敏感性。蜱虫接触受试拟除虫菊酯后的击倒时间非常相似。结果表明,I型拟除虫菊酯(氯菊酯类)的致死剂量会促使蜱虫迅速附着于宿主。相比之下,II型拟除虫菊酯(α-氰基拟除虫菊酯)导致的致命中毒会使蜱虫无法完全附着。文中讨论了加速和阻止附着的可能机制。
