Summary

In 2004 RIMpro-Cydia was developed as a dynamic population model that simulates the
within-year biology of a local codling moth population. The model is meant to be used by
growers and advisors to optimize the control of codling moth populations in organic and
integrated managed orchards. The model is based on literature data and unpublished
research data. Fractional boxcar trains are used to mimic the dispersion in the
developmental processes. The model is run in real time on the data input of local weather
stations, starting on 1 January. The output of the model was compared with the results of
field observations in three years in an untreated orchard. In the years 2005 to 2007 the
progress in egg deposition as predicted by the model was in general agreement with the
field data. The start of the egg deposition period was predicted well. The end of the egg
deposition period was predicted when in the field about 10% of the eggs was still to be
laid. There was no consistency in the relation between cumulated pheromone trap catches
and the cumulative egg deposition as calculated from the field data.
