摘要
本文在室内(T15～28℃和RH66％～87％)及自然环境条件下,初步观察研究了边缘革蜱(Dermacentor marginatus)的生活史和某些生物学特征,并获得了有关参数。其生活史各期经历平均时间为:卵期22天,幼、若虫期分别为24和37天,成虫滞育越冬时间为233天,越冬后寻找宿主吸(饱)血时间为17天,饱血雌蜱孕卵期为15天,产卵期17天,总计一个世代发育周期大约为365天。每只雌蜱日平均产卵264.8粒,一生平均产卵4501粒;卵长宽径值为394.1×340.3μm,卵的孵化率为87.7％;幼、若虫期吸血率分别为69.5％和54.6％,由幼虫到若虫和由若虫到成虫其蜕变率分别为80.1％和94.6％;子代成虫雄雌比例为1∶1.3。以上基础数据,填补了国内对该蜱种生物学研究的某些空缺,对有关自然疫源性疾病的研究具有一定的参考价值。
In our laboratory (T 15-28℃ , RH 66-87%), the life cycle of Dermacentor marginatus was observed preliminarily, and basic biological data were obtained as follows: The average developmental durations of egg, larva, and nymph were 22, 24 and 37 days respectively. The hibernation of the adults in a mimic environment maintaind 233 days in average. The duration of finding a host and engorged with blood was about 17 days in average. The periods of pregnancy and oviposition were 15 and 17 days respectively. Thus, the whole developmental cycle of this tick took about one year.
A female laid 264.8 eggs every day in average, and 4501 eggs in total for the life. The size (length×width ) of the eggs was 394.1×340.3μm in average (n= 10). The rate of egg hatching was 87.7%. The rates of blood sucking of larva and nymph were 69.5% and 54.6% respectively, and the rates of moulting were 80.1% and 94.6% respectively. The sex ratio of male to female was 1 : 1.3.
