摘要
在实验室控制条件下,分别以雌、雄大白鼠为供血动物饲养猫栉首蚤,收集并记录猫栉首蚤每日产卵量,同时用分光光度计测定血便排放量,分析产卵量与排血便量的关系。结果表明,猫栉首蚤的产卵历期平均57天,其中,雌鼠供血组每蚤平均一生产卵量为51.34-11粒,平均每天产卵0.94-0.2粒;雄鼠供血组每蚤平均一生产卵量为57.64-29粒,平均每天产卵1.04-0.5粒,两者产卵量无明显差异;同时猫栉首蚤的产卵量与产卵时间之间呈负相关,其中雌性大白鼠供血的决定系数为0.8002,雄性大白鼠供血的决定系数为0.5835。在一次大白鼠供血周期内,不同性别大白鼠供血时猫栉首蚤的产卵量和排血便量都呈现规律性变化,雌鼠供血组蚤的产卵量与产血便量呈双峰曲线,雄鼠供血组蚤的产卵量为单峰曲线。可见,在实验室控制条件下,猫栉首蚤产卵量与供血大白鼠的性别无关,不存在宿主性别依赖性。产卵量与血便量的变化呈正相关,反映了猫栉首蚤对宿主的适应性及选择宿主的特异性。
The eggs and blood feces of Ctenocephalides felis felis feeding on different gender of white rats were collected everyday in the laboratory under control conditions. The blood feces was analyzed by spectrophotometer for the quantity of the excrement to understand the relationship between fecundity and the blood feces. The results showed that the mean spawning duration of Ct. felis feeding on white rat was 57 days, in which 51.3 ± 11 days for feeding on female white rats with 0.9 ± 0. 2 eggs laying per day and 57.6 ± 29 days for feeding on male with 1.0 ± 0. 5 eggs per day. There was no significant difference in fecundity between fleas feeding on different gender of white rats. There was a negative relationship between the fecundity of Ct. felis and the blood feces excretion with the correlation coefficient 0. 8002 for fleas feeding on female rats and 0. 5835 for fleas feeding on male rat on male rats. For each circle (one circle was 6 days from putting fleas on each animal to dead replaced with another new alive one) of Ct. felis feeding on white rat, both the fecundity and the blood feces excrement of tested flea displayed as the follow : double peaks were shown for the fleas fed on female rats, while one peak for this fleas fed on male ones. From this study, we can see that in laboratory under control condition, there was no relationship between the fecundity and white rat gender, while there was a positive relationship between the fecundity of Ct. felis and the quantity of blood feces excrement.
