The life cycle and reproductive patterns of Triatoma rubrofasciata were studied along with laboratory conditions for the establishment of a prolific colony. The insects were divided into four groups: two of them were maintained at room temperature (20.5 degrees C to 33 degrees C and 85% +/- 5% of relative humidity), the other two in a climatic chamber (CC) (temperature: 29 degrees C, humidity: 80% +/- 5%). The groups were fed weekly or fortnightly on Swiss mice. The females from the group kept in the CC and fed weekly had longer life span, as well as a higher number of eggs, fertile eggs and hatchings; the group kept in the CC and fed fortnightly had a shorter life span for the 1st, 2nd and 3rd instars and a lower mortality rate for all instars. It was concluded that a constant high temperature (CC at 29 degrees C) is the most suitable condition for the maintenance of a colony of T. rubrofasciata regardless of the interval between repasts.
研究了红带锥蝽的生命周期和繁殖模式，以及建立高产种群的实验室条件。昆虫被分为四组：其中两组在室温（20.5摄氏度至33摄氏度，相对湿度85%±5%）下饲养，另外两组在气候箱（CC）中饲养（温度：29摄氏度，湿度：80%±5%）。这些组每周或每两周用瑞士小鼠喂食一次。饲养在气候箱中且每周喂食的组中的雌性寿命更长，产卵数、受精卵数和孵化数也更多；饲养在气候箱中且每两周喂食的组中，一龄、二龄和三龄若虫的寿命较短，所有龄期的死亡率较低。得出的结论是，无论喂食间隔如何，恒定的高温（气候箱中29摄氏度）是维持红带锥蝽种群的最合适条件。
