Abstract
A simple soil temperature driven phenology model for the spring emergence of the apple sawfly Hoplocampa testudinea KLUG is reviewed.
It is based on the relationship between temperature and developmental rate and makes use of a time-varying distributed delay.
It is validated with independent field and semi-field data.
The basic version of the model is expanded to include winter dormancy as a braking factor in the initial phase of the post-diapause development.
Furthermore the temperature dependence of the development is compared for sawfly populations from different origins in order to assess the geographic validity range of the model.
