Abstract: The life span of Haemaphysalis longicornis Neumann lasted 135.8 d in average under laboratory conditions (27±1°C, 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<0. 001). The reproductive efficiency index (RED 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.
