Jump performances of Ctenocephalides canis and Ctenocephalides felis felis have been measured and compared on unfed young imagos. The mean length of the C. felis felis jump was 19.9+/-9.1cm; minimum jump was 2cm, and the maximum was one 48cm. The C. canis jump was significantly longer (30.4+/-9.1cm; from 3 to 50cm). For height jump evaluation, grey plastic cylindric tubes measuring 9cm in diameter were used. Their height was increasing from 1 to 30cm by 1cm. Groups of 10 fleas of the same species were deposited on the base of the tube. The number of fleas which succeeded in jumping above the tube was recorded. The mean height jump carried out by 50% of fleas was calculated after linearisation of the curves: it was 15.5 and 13.2cm for C. canis and C. felis, respectively. The highest jump was 25 for C. canis and 17cm for C. felis.
已对未进食的年轻成年犬栉首蚤和猫栉首蚤指名亚种的跳跃性能进行了测量和比较。猫栉首蚤指名亚种跳跃的平均长度为19.9±9.1厘米；最小跳跃距离为2厘米，最大跳跃距离为48厘米。犬栉首蚤的跳跃距离明显更长（30.4±9.1厘米；3至50厘米）。为了评估跳高，使用了直径9厘米的灰色塑料圆柱管。其高度从1厘米到30厘米以1厘米的幅度递增。将每组10只同一物种的跳蚤放置在管的底部。记录成功跳到管上方的跳蚤数量。在曲线线性化后计算出50%的跳蚤进行的平均跳高：犬栉首蚤和猫栉首蚤的平均跳高分别为15.5厘米和13.2厘米。犬栉首蚤的最高跳跃高度为25厘米，猫栉首蚤为17厘米。
