Summary A model formulated to provide a theoretical basis for the interpretation of developmental responses to photoperiod is presented. Experimental data on the photoperiodic determination of diapause and non-diapause in the European corn borer,Ostrinia nubilalis, were used to estimate the required characteristics of the model. The prototype model, presented in the previous paper (I) of this series (Beck, 1974) postulated the existence of a photoperiodically regulated time period during which developmental alternatives are determined; this time period was called the Determination Gate (DG). The present study includes determination of the characteristics and kinetics of a model system [the (P)-system] underlying the temporal placement of DG. The effects of photophase duration on subsequent DG placement are also presented.
