This study aimed to evaluate the survival possibility of the Lynxacarus radovskyi life cycle stages out of the host under laboratory conditions. Eggs, immature and adult forms of L. radovskyi were collected from cats naturally parasitized. The collected specimens were separated and put into plastic containers and into Durhan pipes, being submitted to room temperature and humidity, in the Parasitic Diseases of Domestic Animals Laboratory – DMV – UFRPE, and in climatic chamber at temperature of 27 ºC ± 1ºC and relative humidity > 70%, in scotophase, with and without cat hair supply as substrate to evaluate the survival capacity of the stages out of the host. There was a 100% hatch of the collected eggs, with larval survival within one to four days; the survival for the collected larvae was from one to five days. For all the experiment phases the nymphs presented bigger survival average than the other ones. In general, females survived more than males. The addition of hair provided a bigger survival to all the mite stages.
