摘要
为了解嗜群血蜱在苍溪县的分布与危害、宿主种类、季节活动规律、群体生态形成的原因及一些生物学特性，采用宿主体检蜱法、拖旗法、布旗覆盖法采集动物体表和野外环境的蜱，对其进行了形态鉴定和药物防制试验。结果显示，苍溪县嗜群血蜱的流行面达97．4％，人感染率53．8％，动物感染率7．7％～100％；嗜群血蜱的寄生宿主有15种，主要活动期为4～9月份；吸血后引起叮咬部位皮肤丘疹、红肿、瘙痒，甚至感染溃烂，伤口愈合后痒痛和色素斑可持续数月。依据上述结果提出了防控嗜群血蜱的建议。
The morphological identification and drug prevention experiment were carried out on Haemaphysalis concinna collected from animals and the environment by host body examination, flag dragging and cloth flag covering method. Results showed that H. concinna occurred in 97.4% areas of Cangxi County, and the infection rate of H. concinna in human and animals were 53.8% and 7.7%-100%, respectively. H. concinna were found in 15 species of animals and were active from April to September. Infection with H. concinna resulted in skin rashes, red swelling, itching, even infected ulcerations in bitten sites after bloodsucking and the itching sore and pigmented spots lasted for months after wound healing. Control measures for the control of H. concinna were proposed according to these findings.
