The quantity of eggs and feces deposited by replicate populations of cat fleas, Ctenocephalides felis (Bouché), from domestic house cats. Felis catus, were recorded at 1-h intervals over a 24-h period, in a photoperiod of 12:12 (L:D) (photophase, 0600-1800 hours [EST]). Egg production averaged 23.96 +/- 0.83 eggs per female per day and was greatest from 2400 to 0300 hours and lowest from 0700 to 0900 hours and from 1700 to 1900 hours. Daily fecal deposition was 0.77 +/- 0.03 mg feces per flea and did not vary significantly among hours. Flea eggs and adult feces were dropped continuously from infested cats, but significantly more eggs were shed at times of day when cats normally rest. More feces are concentrated in the small areas where cats rest than over the large areas they roam. Consequently, eggs and feces would not be deposited uniformly throughout the hosts home range, resulting in a clumped distribution of larval development sites at host resting areas.
对来自家猫（Felis catus）身上的猫栉首蚤（Ctenocephalides felis (Bouché)）的重复种群所产的卵和粪便量进行记录。在12:12（光照:黑暗）的光周期（光照阶段为东部标准时间06:00 - 18:00）下，每隔1小时记录一次24小时内的情况。平均每只雌蚤每天产卵23.96 ± 0.83枚，产卵量在00:00至03:00时最高，在07:00至09:00时以及17:00至19:00时最低。每只蚤每天的粪便排放量为0.77 ± 0.03毫克，各小时之间无显著差异。感染蚤的猫会持续掉落蚤卵和成虫粪便，但在猫通常休息的时段，掉落的卵显著更多。猫休息区域的小范围内集中的粪便比其活动的大范围区域更多。因此，卵和粪便不会均匀地分布在宿主的整个活动范围内，导致幼虫发育场所聚集在宿主休息区域。
