Studies were conducted of the effect of temperature and humidity, variant of plague microbe, frequency and duration of feeding and specificity of the host on the blockformation in the souslik fleas C. tesquorum and N. setosa infected with plague. 28 tests on the effect of temperature and humidity on the blockformation were undertaken, for which 14411 fleas of the above species were used. A temperature of 16 to 22 degrees proved to be optimal; at this temperature the number of blocked fleas (C. tesquorum) varied from 21.2 to 42.7% and that of N. setosa--from 41.9 to 54.2%. Marmot variant of plague microbe caused the formation of the "block" in 53.3 to 55.1% of fleas of N. setosa in 3-4 days and in 28.0 to 42.7% of C. tesquorum in 10-14 days after the infection. In C. tesquorum the process of blockformation is affected by the frequency of feeding, in N. setosa--by the duration of each feeding.
开展了关于温度和湿度、鼠疫微生物变种、进食频率和持续时间以及宿主特异性对感染鼠疫的灰旱獭跳蚤和谢氏山蚤形成菌栓的影响的研究。进行了28次关于温度和湿度对菌栓形成影响的试验，为此使用了上述种类的14411只跳蚤。结果证明，16至22摄氏度的温度最为适宜；在此温度下，形成菌栓的灰旱獭跳蚤数量在21.2%至42.7%之间，谢氏山蚤数量在41.9%至54.2%之间。鼠疫微生物的旱獭变种在感染后3至4天使53.3%至55.1%的谢氏山蚤形成“菌栓”，在10至14天使28.0%至42.7%的灰旱獭跳蚤形成“菌栓”。在灰旱獭跳蚤中，菌栓形成过程受进食频率影响，在谢氏山蚤中，则受每次进食持续时间影响。
