In-Depth Information
At the present, phenology models in SOPRA are established for Rosy apple aphid (
Dysaphis
plantaginea
) Apple sawfly (
Hoplocampa testudinea
), Codling moth (
Cydia pomonella
), Smaller
fruit tortrix (
Grapholita lobarzewskii
), Apple blossom weevil (
Anthonomus pomorum
), Summer
fruit tortrix (
Adoxophyes orana
), European pear psylla (
Cacopsylla pyri
) and European cherry
fruit fly (
Rhagoletis cerasi
). Recent validation of two new models extends the coverage of
major pome and stone fruit pests by European red spider mite (
Panonychus ulmi
) and Plum
tortrix (
Grapholitha funebrana
).

2.3 Habitat selection and simulation of habitat temperatures
The implementation of temperatures in the models is based on intensive studies of habitat
selection of the developmental stages and biophysical modelling using the three driving
