用实验室饲养的特新蚤指名亚种，在室温条件下叮咬8位志愿者前臂的观察显示，在饥饿后第1、第4和第6天的吸血率分别为54．04％（107／198）、49．23％（32／65）和63．08％（41／65），总吸血率为54.88％（180／328），证明该蚤具有嗜吸人血的特性。在温度18±1℃，相对湿度70±5％的条件下，饥饿幼龄蚤寿命为6.1天（1～17天），成龄蚤5．57天（1～10天）；吸血蚤寿命42．2天（7～70天）。新羽化蚤体重O．294±0．185mg，吸血后成蚤体重0．524±0．208mg。平均吸血量雌蚤为0．364mg（0．00038ml），雄虽为0．091mg（0．0000884ml）。
Observations of the forearm of eight volunteers biteing at room temperature with laboratory-designated fleas named subspecies showed that the rate of aspiration on the 1st, 4th and 6th day after starvation were 54.04% (107 / 198), 49.23% (32/65) and 63.08% (41/65), respectively. The total rate of aspiration was 54.88% (180/328). Under the conditions of temperature 18 ± 1 ℃ and relative humidity 70 ± 5%, the life span of starved young flea was 6.1 days (1-17 days), adult flea 5.57 days (1-10 days), life span of sucking flea .2 days (7 to 70 days). New eclosion flea weight O. 294 ± 0.185mg, after taking blood flea weight 0.524 ± 0.208mg. The average amount of blood sucked female flea 0.364mg (0.00038ml), male was 0.091mg (0.0000884ml).
