1984～1985年在实验室内,以小白鼠做为喂血动物,研究了方形黄鼠蚤松江亚种的吸血活动。结果表明:该蚤吸血率与温度的关系呈抛物线型,25℃左右时吸血率最高。繁殖蚤吸血率一般高于新羽化蚤。雌性吸血率一般高于雄性。在一定温度范围内吸血时,不同温度下吸血量近相等。繁殖蚤吸血量一般大于新羽化蚤。雌性吸血量一般大于雄性。血液消化速度在一定范围内随温度的升高而加快。25℃以下时,繁殖蚤消化速度一般较新羽化蚤为快;而30℃以上时,繁殖蚤和新羽化蚤消化速度相近。雄雌消化速度无大差别。
1984 to 1985 in the laboratory, with white mice as blood-feeding animals to study the square rat shrimp Songjiang subspecies vampire activity. The results showed that the relationship between the blood-sucking rate and the temperature of the flea was a parabola, and the highest blood-sucking rate was found at about 25 ℃. Breeding fleas sucking rate is generally higher than the new eclosion flea. Female sucking rate is generally higher than males. In a certain temperature range of blood, the amount of blood sucked at nearly the same temperature. Breeding fleas blood absorption is generally greater than the new eclosion flea. Female sucking blood is generally greater than the male. Blood digestion speed within a certain range with the temperature rise and speed up. Under 25 ℃, the breeding fleas digestion rate is generally faster than the new eclosion flea; and more than 30 ℃, the breeding flea and the new feather flea digestion speed is similar. Male and female digestion rate is no big difference.
