RESUMO

Development of resting eggs of Polyphemus pediculus is asynchronous. The hatching of young is wave-form in character; it occurs by portions in accordance with the native diurnal, seasonal, perennial rhythms, as well as the environmental conditions survived by a population during the resting period. The species cyclicity is genetically determined. P. pediculus is a monocyclic species under any conditions. Local P. pediculus populations are genetically heterogeneous and formed by generations having different duration of the life cycle.
