要約

Polyphemus pediculus reproduce themselves by means of both parthenogenesis and gamogenesis, which take place simultaneously. The individual fecundity of females depends on their age, season of the year, and geographical zone. Production of subitaneous eggs depends on the environmental temperature to greater extent than that of the latent eggs. The population variability of P. pediculus fecundity is wider than it was stated for the class of Crustacea.
