title: [Life expectancy of Ctenophthalmus wladimiri Is.-Gurv., 1948 (Siphonaptera, Ctenophthalmidae) under laboratory conditions].
abstract: Laboratory studies have shown that at 75% humidity fleas, Ct. wladimiri, are less viable than at 100% humidity. At 100% humidity at a temperature from 0 to 10 degrees and without feeding newly born imagos survived up to 363 days, at a higher temperature from 18 to 30 degrees-from 44 to 163 days. At a temperature from 7 to 10 degrees imagos, which fed one time, lived up to 355 days and at 0 to 2 degrees-up to 287 days. Maximum life duration (1133 days) for periodically feeding fleas was at 100% humidity at a temperature from 7 to 10 degrees. Under such conditions 50% of fleas survived up to 114 days. Hungry but previously "prepared" for winter fleas lived at a temperature from 0 to 2 degrees not more than 376 days.
