Two experiments were conducted on dogs to evaluate interval to initiation and duration of the first blood meal of Ctenocephalides canis (Curtis). Percentage of fed male and female fleas was calculated for fleas held on dogs for 5, 15, 30, 60 min, 6, and 24 hr. Duration of first blood meal was also measured for individual fleas confined on dogs. When fleas were free in the hair coat, 21.2% had begun blood feeding within 5 min. After 1 hr, 72.5% of fleas had fed. After 6 hr, 95.2% of males and 100% of females had taken a blood meal, and 24 hr after deposition all fleas had fed. There was no significant difference between the 2 sexes. The mean delay between deposition and biting for fleas that began feeding within 15 min was 2 min 52 sec +/- 3 min 2 sec for female fleas and 3 min 8 sec +/- 2 min 45 sec for males. The mean duration of female and male meals was 5 min 3 sec +/- 3 min 41 sec and 6 min 9 sec +/- 6 min 8 sec, respectively. There was no significant difference between the 2 sexes. The dog flea took its blood meal on dogs more slowly than the cat flea did on cats; this meal was significantly longer for Ctenocephalides felis felis (Bouche) than for C. canis.
进行了两项针对犬只的实验，以评估犬栉首蚤（柯蒂斯）首次吸血的起始间隔和持续时间。计算了在犬只身上停留5分钟、15分钟、30分钟、60分钟、6小时和24小时的雌雄跳蚤的进食百分比。还测量了限制在犬只身上的单个跳蚤首次吸血的持续时间。当跳蚤在毛发中自由活动时，21.2%的跳蚤在5分钟内开始吸血。1小时后，72.5%的跳蚤进食。6小时后，95.2%的雄蚤和100%的雌蚤吸食了血液，放置24小时后所有跳蚤都已进食。两性之间没有显著差异。在15分钟内开始进食的跳蚤，雌蚤从放置到叮咬的平均延迟为2分52秒±3分2秒，雄蚤为3分8秒±2分45秒。雌蚤和雄蚤进食的平均持续时间分别为5分3秒±3分41秒和6分9秒±6分8秒。两性之间没有显著差异。犬蚤在犬只身上吸血的速度比猫蚤在猫身上吸血的速度慢；猫栉首蚤（布歇）的这一餐明显比犬栉首蚤的长。
