In the fleas Leptopsylla segnis settled on white mice the steady egg-laying took place under conditions including three factors--darkness, high relative air humidity (80-100%) and the "smell of host nest". The absence of anyone of these factors reduced an egg-production by 34-56%. The removal of the "smell" source coupled with substitution of high air humidity on low one (50-60%) interrupted the egg-laying almost completely inspite darkness or light. Owing such reaction on joint influence of the "smell of host nest" and air humidity the fleas are capable to interrupt and to recommence egg-laying depending on either the host is outside or in the nest.
在寄生于小白鼠身上的缓慢细蚤中，稳定产卵发生在包含三个因素的条件下——黑暗、高相对空气湿度（80 - 100%）以及“宿主巢穴气味”。缺少这些因素中的任何一个都会使产卵量减少34 - 56%。去除“气味”源并将高空气湿度替换为低空气湿度（50 - 60%），几乎会完全中断产卵，无论处于黑暗还是光亮环境。由于对“宿主巢穴气味”和空气湿度共同影响的这种反应，跳蚤能够根据宿主在巢穴外还是在巢穴内来中断和重新开始产卵。
