The authors pay attention to an occurrence of the taxon Ceratophyllus sciurorum sciurorum (Schrank, 1803) (Siphonaptera) in Slovakia during the whole season. The curve of occurrence this taxon of fleas has showed two high points. The first top has been achieved in April and second one followed in October. In December the authors have noticed a period and named it "cocoon block". This course of the curve has been found at the species from family Myoxidae, mostly. On the other hand, the course of curve of the birdboxes nesters has the opossite position, the high points have been recorded in autumn. A conspicuous differences has been probably caused by different biology of nesters of Myoxidae and birds in boxes. The ratio of males to females these ecological groups of hosts was different, too.
作者关注了松鼠角叶蚤指名亚种（Ceratophyllus sciurorum sciurorum）（Schrank，1803年）（蚤目）在斯洛伐克一整个季节中的出现情况。该蚤类分类单元的出现曲线显示有两个高峰。第一个高峰出现在4月，第二个高峰在10月。12月作者注意到了一个时期，并将其命名为“茧阻断期”。这种曲线变化过程在睡鼠科物种中最为常见。另一方面，在鸟巢筑巢者的曲线变化过程中情况则相反，高峰出现在秋季。这种显著差异可能是由睡鼠科动物和在鸟巢中筑巢的鸟类不同的生物学特性导致的。这些生态宿主群体中雄性与雌性的比例也有所不同。
