Abstract:
:Eight species of carabids (six of them represented by two subpopulations) were sampled. It appeared that the mean number of ripe eggs in the ovaries could be regressed on the specific body weight (ranging from 20 to 285 mg dry wt.): the mean decreased in heavier species, and was higher in the autumn breeders than in the spring breeders. The rate of disappearance of ripe eggs from ovaries, estimated at the end of the reproductive season, was regarded as the egg deposition rate. It turned out to be inversely correlated with the actual female mobility. The calculated fecundities in the separate species and subpopulations with the same type of development could be satisfactorily regressed on the specific body weight. Thus, the developmental type, the specific body weight, and actual female mobility are involved in egg production and deposition.
