摘　　要：目的了解某部驻区蜱类的种群构成、密度与分布情况,为做好蜱媒传染病预防工作提供依据。方法采用人工布旗小时法进行蜱密度的调查,在部队营区内草丛中及部队驻地附近小道旁边的草丛和周围林区中人员经常涉足的地方进行调查,连续调查3 d;寄生蜱从当地居民饲养的羊和营区的军犬体表采集。将采集的蜱收集于含75%酒精的小瓶中带回实验室鉴定。结果所捕获的蜱均为长角血蜱,蜱密度为16只/布旗人工小时;捕获的497只蜱中寄生蜱449只、游离蜱48只,雌性210只、雄性287只,成虫478只、若虫19只,饱血状态117只、未饱血380只。在当地的12只羊体表采集到393只寄生蜱,平均每只羊体表寄生32.75只蜱;在营区中的2条军犬体表采到56只蜱。结论调查区域存在长角血蜱,且家畜和军犬体表寄生蜱较多;提出了开展蜱类调查时的注意事项。Objective To understand the population composition,density and distribution of ticks in a military base,so as to give the principle to prevent the tick-borne disease. Methods Using the manual counting method with banners by hour,to investigate on the grassland in and around the camp and places where people often step in around the forest areas,for continuously 3 days; To collect the parasitic ticks from the surfaces of sheep raised by local residents and military dogs. Put the tick samples in a small bottle contains 75% of alcohol and bring it back to indentify in the lab. Results All of the ticks collected are the Heamaphysalis longicornis,the density of the ticks is 16 / banner manaul counting hour; In all 497 ticks,there are 449 parasitic ticks,48 free ticks,210 females,287 males,478 adults,19 nymphs,117 full blood status and 380 not full blood status. Collected 393 parasitic ticks from 12 sheep surfaces,the mean value of the parasitic tick is32. 75 / sheep; Collected 56 ticks from 2 dog surfaces in the camp. Conclusions The presence of heamaphysalis longicornis is exact in the survey area,and there are many parasitic ticks on the surface of the sheep and dogs; propound the matters need attention when establish tick investigation.
