The entire life cycle of Rhodnius domesticus, fed weekly on mice, was studied under controlled conditions. Aspects related to hatching, life time, mortality, feeding behaviour and fecundity for each stage of the insect life-cycle were evaluated. The hatching rate observed in 100 eggs was 57% and the mean time of hatching was 15.6 days. Forty-six nymphs (80.7%) completed the cycle and the mean time from NI to adult was 93.8 days. The average span in days for each stage was 12.4 for NI, 9.8 for NII, 14.2 for NIII, 16.8 for NIV and 25.0 NV. the number of bloodmeals in each nymphal stage varied from 1 to 3. The mortality rate was 12.3% for NI, 3.5% for NII and 1.7% for NIII and NV nymphs. The mean number of eggs laid per female in a 9-month period was 333.1. Average adult survival rates were 287.6 + 133 and 328 + 73 days for males and females respectively.
在可控条件下研究了以小鼠为食、每周喂食一次的家红猎蝽的整个生命周期。对昆虫生命周期各阶段的孵化、寿命、死亡率、取食行为和繁殖力等方面进行了评估。在100枚卵中观察到的孵化率为57%，平均孵化时间为15.6天。46只若虫（80.7%）完成了整个周期，从一龄若虫到成虫的平均时间为93.8天。每个阶段的平均天数为：一龄若虫12.4天，二龄若虫9.8天，三龄若虫14.2天，四龄若虫16.8天，五龄若虫25.0天。每个若虫阶段的吸血次数从1次到3次不等。一龄若虫的死亡率为12.3%，二龄若虫为3.5%，三龄和五龄若虫为1.7%。在9个月的时间里，每只雌性产下的平均卵数为333.1枚。雄性和雌性成虫的平均存活时间分别为287.6±133天和328±73天。
