Photoperiod affected the production of cat flea eggs by cats infested with cat flea, Ctenocephalides felis (Bouché). Cat flea eggs have a smooth chorion and do not adhere to the host. About 60% of fluorescing eggs placed in the pelage were recovered in collecting trays underneath the host in 2 h. An average of 87.7 eggs per cat was laid during the last 8 h of the scotophase compared with 49.9 and 59.1 eggs during the other 8-h periods. Significant variation in the number of eggs collected daily existed among the six cats. The activity budgets were similar for all the cats with the maximum sleep period during the photophase. The possible adaptive advantages of synchronizing egg production with photoperiod are discussed.
光周期影响感染猫栉首蚤（Ctenocephalides felis (Bouché)）的猫所产猫蚤卵的数量。猫蚤卵有一层光滑的卵壳，不附着于宿主。置于猫皮毛上的约60%的荧光卵在2小时内于宿主下方的收集托盘中被回收。在暗期的最后8小时内，每只猫平均产卵87.7枚，而在其他8小时时间段内分别为49.9枚和59.1枚。六只猫之间每日收集到的卵数量存在显著差异。所有猫的活动预算相似，在光照期睡眠时长最长。本文讨论了使产卵与光周期同步的可能适应性优势。
