title: The effect of temperature on photoperiodic induction of diapause in insects and mites: a model for the photoperiodic "counter".
abstract: Existing models for the accumulation of photoperiodic information (the photoperiodic "counter") cannot explain satisfactorily the various effects of temperature on diapause induction in insects and mites, nor the observation that in several insect species the so-called "required day number" has a high degree of temperature compensation. In the model presented in this paper the effect of temperature has been incorporated in such a way that both the rate of increase of the "induction sum" (or "diapause titre") and the level of the "minimally required induction sum" (or "threshold level") are temperature dependent. The proposed model is in accordance with observed temperature effects, and gives an explanation for a temperature-compensated "required day number".
