我国东北三省蜱类的分布及医学重要性

目的调查东北三省蜱类的分布及医学重要性。方法采用人工布旗法采蜱，从动物体采集蜱。结果东北三省的蜱类现知2科7属21种，其中辽宁省18种，吉林省13种，黑龙江省11种。东北区分布16种，其中松辽平原亚区分布13种，长白山亚区分布9种，大兴安岭亚区分布3种；蒙新区东部草原亚区分布12种。在东北地区，全沟硬蜱、森林革蜱、嗜群血蜱和日本血蜱是森林脑炎的媒介；全沟硬蜱是莱姆病的媒介；嗜群血蜱是北亚蜱传斑点热的媒介。结论对东北三省蜱类的分布及医学重要性的调查为东北三省蜱类的区系分布和蜱媒病防治提供了重要依据。

Distribution and medical importance of ticks in three provinces of northeast China

Objective To investigate species distribution and medical importance of ticks in three provinces of northeast China, Methods Collecting ticks by dragging a blanket over the vegetation on the ground, and collecting on the faunae. Results 21 species ticks belonging to 7 genera, and 2 family had been known in three provinces of northeast China, of which 18 species distributed in Liaoning province, 13 species distributed in the Jilin province, and 11 species distributed in the Heilongjiang province. 16 species were recorded with distribution in north-eastern district, of which 13 species were recorded with distribution in Songliao -plains subterritory, 9 species in Changbais-han subterritory, 3 species in Daxinganling subterritoy; 12 species were recorded with distribution in eastern-grasslands subterritoy of Mongolia - xinjiang district. Encephalitis acarina orientalis was infected by Ixodes persulcatus, Dermacentor silvaram, Haemaphysalis concinna, and Haemaphysalis japonica ; Lyme disease was infected by Ixodes persulcatus; Rickettsiosis sibirica was infected by Haemaphysalis concinna in northeast region of China. Conclusion The study provided the basis on faunal distribution of ticks and control of infectious disease by ticks in three provinces of northeast China.
