蜱的化学感觉系统与驱避剂的研究进展

Research progress on the chemical sensing system and repellents of ticks

蜱是一种媒介寄生虫,通过吸血可导致宿主营养不良,且能够传播多种病原体,造成经济损失,威胁公共健康。目前蜱的防治主要使用化学药物,而化学杀虫剂的广泛使用引发的环境污染与毒性问题逐年暴露,因此寻找与化学感觉相关的靶点或者天然安全的驱避剂是蜱防控的关键。目前发现蜱的化学感觉系统在蜱寻找宿主过程中起重要作用,可以作为新的研究方向。本文综述了蜱的化学感觉系统及不同驱避剂的利弊,以期为蜱的防控提供依据。

Tick is an ectoparasite and disease vector.Ticks can cause malnutrition in the host and spread a variety of pathogens through its blood-feeding activity,which may inflicting economic loss and posing a threat to public health.Currently,chemical pesticide is the dominant approache for controlling tick.However,this approach also provides risk to the environmental and toxicity to the hosts.Therefore,it is necessary to explore novel targets responsible for chemical sense in ticks and natural and safe repellent.To date,it is know that chemical sensing system in ticks has a critical role in searching for hosts,providing opportunities for further research.This article reviewed the tick chemical sensing system and different repellents in order to facilitate the control of ticks.
