Summary in the original language of the document

A combined strategy of various direct (granuloviruses; nematodes) and indirect measures (population models, pheromone traps) can lead to a reduction in codling moth populations in the long term.
Practical recommendation
Codling moth population model:
• Forecasting models such as the Fruitweb model can be used to predict treatment dates and reduce the need for spray treatments.
• Codling moth forecasting models provide predictions of possible egg-laying and hatching dates and help fruit growers make more accurate codling moth treatment decisions.
• The Fruitweb model shows the current course of a codling moth population (moth flight, egg laying, larval development) in the orchard; codling moth development depends on climate, location/site, temperature and day length.
• The Fruitweb model is based on the codling moth model by Graf, Höhn, Höpli and Kuske (2018).
• For targeted and optimized control, own infestation monitoring (attractant traps) and the recommendations from agricultural advisors should always be used additionally.
Explanation of the codling moth Fruitweb model (Picture 1)
• The forecast models are calculated with approximate population strengths; the respective local weather conditions are included in the calculation; the calculation is performed retrospectively with the measured weather data and prospectively with the weather forecasts.
• The upper diagram shows the course of the borings (red dotted line), as well as the number of larvae in the respective larval stages (larval stages L1-L5: various shades of orange and yellow, see legend on the bottom).
• The middle diagram shows the daily oviposition, i.e., the number of eggs per day (red line).
• The lower diagram shows (in green) the number of fertile females per day, the flight of the females depends mainly on the weather conditions and the time of day (crepuscular).

EPrint Type:Practice tool
What problem does the tool address?:The codling moth Cydia pomonella is one of the most important pests in organic fruit growing. Damage is caused by the feeding activity of the larvae. Heavy codling moth infestation can lead to massive yield losses.
What solution does the tool offer?:In addition to pheromone traps (attractant traps) for flight monitoring, various monitoring/population models such as RIMpro and Fruitweb can be consulted, which use various parameters to calculate codling moth hatching and egg laying.
