Abstract: The fleas Neopsylla bidentatiformis(Wagner, 1893)and Citellophilus tesquorum sungaris (Jordan, 1929)can live for many days after one feed, life duration in relation to environmental temperature may be expressed by the curve log Y=a-b logX, the temperature high the life duration short; however, relation between life duration and environmental humidity is the curve log Y=a-b log (K-X),the humidity high the life duration long. In the reproduced fleas, hunger resistance of female is stronger than that of male, but no sexual difference is found in the hunger resistance of newly emerged fleas.
