To determine the association between the sex, age and temperature of fleas Citellophilus tesquorum sungaris and their blood-sucking rate, engorged quantity, or digestion speed, using the logistic regression and the multiple regression methods, respectively, the results were as follows.

Nine flea species were found from the ground squirrel burrow nest,body and burrow track,among which Citellophilus tesquorum sungaris was the dominant species (89 65%) and Neopsylla bidentatiformis came the second (10 26%).

In this paper, we mainly analyse the survival data of citellophilus tesquorum sungaris (Jordan,1929), which come from Ma li-ming′s laboratory studies in 1985-1990 on four different conditions: temperature, relative humidity, frequency of blood feeding and sex.
