[The factors that regulate oviposition in Leptopsylla segnis (Leptopsyllidae: Siphonaptera) fleas].
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.
