This work is focused on the relations between seasonal rythms and the variation in the number of days elapsed between two successive depositions of larvae in Asellus aquaticus L. (Crust. Isop.). The individuals studied at this purpose were all kept at 18 °C and natural photoperiod; some of them had always lived at these conditions, while others were coming monthly from their natural habitat. It was shown that there is a linear relation between an increase in day length and a decrease in the number...
Seasonal variations in brood size have been described in samples of Asellus aquaticus (L.) Crust. Isop.; the samples were caught monthly in a freshwater pool and kept in the laboratory, at constant tem perature and exposed to natural light. It was shown that: (1) the average number of larvae per deposition varies from about 35 (in summer) to about 50 (in winter); (2) when the brood size reaches maximum or minimum values, the mating frequency reaches minimum or maximum values respectively, reestablishing...
