[Seasonal reproduction of Porcellio variabilis Lucas, 1846]

Porcellio variabilis is common and very widespread in Tunisia. Its breeding period lasts from February to October with a cessation during the months of November, December and January. The recruitment of young takes place principally between April and July. Virgin and mated females reared with natural photoperiod in the laboratory show that the initiation of reproduction does not depend on mating; however, it is accelerated when the male is present, the preparturial moult being shorter in females reared in the presence of a male.
