The duration of the development and survival of preimaginal stages of fleas at a temperature of 5 to 30 degrees and relative humidity of 60 to 90% was studied. Minimal average duration of the development an the highest survival rate at all stages were registered at a temperature of 20 to 25 degrees and humidity of 85 to 90%. Under these conditions the whole cycle from egg to image lasts on an average 23 days. The threshold of the development for different stages falls within the limits of 3 to 6 degrees. The duration of the development of all stages was distinctly affected by temperature while the duration of larval development was affected as well by humidity. The survival of larvae was found to be affected by humidity while the survival of individuals in cocoons was considerably affected by temperature.
研究了在5至30摄氏度温度和60至90%相对湿度条件下跳蚤幼期发育和存活的持续时间。在20至25摄氏度温度和85至90%湿度条件下，发育的平均持续时间最短且各阶段存活率最高。在这些条件下，从卵到成虫的整个周期平均持续23天。不同阶段的发育阈值在3至6摄氏度范围内。各阶段的发育持续时间受温度影响显著，而幼虫发育持续时间也受湿度影响。发现幼虫的存活受湿度影响，而成茧个体的存活受温度影响较大。
