摘要
实验室条件［（２７±１）℃；７５％ＲＨ；６Ｌ：１８Ｄ］下，长角血蜱完成其生活史需１３５．８ｄ：卵的孵化期为３８．５ｄ；幼虫吸血前期、吸血期和蜕皮前期分别为５．３ｄ，３．８ｄ和１３．９ｄ；若虫吸血前期、吸血期和蜕皮前期分别为７．２ｄ，５．４ｄ和１６．９ｄ；成虫吸血前期、吸血期、产卵前期和产卵期分别为７．６ｄ，９．４ｄ，７．８ｄ和２０．０ｄ。雌虫饱食体重与产卵量之间存在非常显著的正相关（ｒ＝０．９４９６，Ｐ＜０．００１）。雌虫的生殖效率指数ＲＥＩ＝１１．０６，生殖适合度指数ＲＦＩ＝７．１９。生活周期在不同季节无明显变化。雄虫吸血期受雌虫吸引而成功地交配，这一过程是在吸引性信息素的作用下完成的。
The life span of Haemaphysalis longicornis Neumann lasted 135 8 d in average under laboratory conditions (27±1℃,75%RH,6L:18D). The mean durations for the various stages of the life cycle were as follow: egg period 38 5 d; prefeeding, feeding and premoulting periods of larva 5 3, 3 8 and 13 9 d respectively, those of nymph 7 2, 5 4 and 16 9 d; prefeeding, feeding, preoviposition and oviposition periods of adult female 7 6, 9 4, 7 8 and 20 0 d respectively. In addition, there existed a highly significant correlation between the engorgement body weight of female and the egg mass (r=0 949 6, P<0001). The reproductive efficiency index(REI) and reproductive fitness index (RFI) in female were 11 06 and 7 19 respectively. The life cycle did not significantly change along with seasons. During adults feeding period, males were attracted by females so as to achieve copulation and this process was regulated by an attractant sex pheromone.
