河南省不同地理区划长角血蜱对宿主选择性的研究

Investigation on the selectivity of Haemaphysalis longicornis for hosts in different geographic zoning of Henan

目的了解河南省不同地理区划长角血蜱的宿主选择情况。方法采用动物体表查捉法调查七个地理区划中长角血蜱对不同宿主的侵害情况,统计宿主的阳性率。结果在家养动物中,被调查宿主数量及宿主阳性率居前三位的依次是羊(1231,57.8%)、牛(513,46.0%)和狗(373,38.9%)。在野生动物中,被调查的兔、鼠、刺猬的阳性率分别为40.8%、21.3%、100.0%。被调查宿主平均阳性率47.9%。在河南省七个地理区划中,5个地区的优势家养宿主为羊,2个地区的优势家养宿主为牛。结论河南省长角血蜱的优势宿主为羊、其次为牛,不同地理区划的优势宿主不全相同。

Objective To investigate the selectivity of Haemaphysalis longicornis for the hosts in different geographic zoning of Henan province. Methods Animals body surface method was used to research the invasion situation of Haemaphysalis longicornis to different animals in seven geographic zonings. Data was counted to understand the positive rate of hosts. Results The hosts of domestic animals whose qunatity and positive rate occupied first three plaecs were sheep（1231, 57.8 %） cow（513, 46.0 %） and dog（373, 38.9 %）. The hosts of wild animals which were investigated were rabbit mouse and hedgehog and the positive rate were 40.8 %、21.3 %、100.0 % successively. The average positive rate of hosts was 47.9 %. Sheep was the regnant host of domestic animals in five places of the seven geographic zonings in Henan province, and cow was the regnant host in the other two places. Conclusions The first regnant host of Haemaphysalis longicornis is sheep and second is cow in Henan province. The regnant hosts in different geographic zonings are not all the same species.
