[Development of the larvae inside the body of the itch mites Sarcoptes scabiei (L.) (Sarcoptidae) and the ontogenetic level of eclosion in mites of the order Acariformes].

Several larvae-containing females of Sarcoptes have been found in skin biopsy of heavily infected Rangifer tarandas L. A. viviparity hypothesis is disproved. The larvae in the body of egg-containing dead females of the human Sarcoptes were obtained by incubation in the suspended water drop. Embryogenesis types as well as eclosion stage in Acariformes are discussed. The term "postmortal pregnancy" is proposed.
