Codling Moth Flight Model Factsheet

Codling moth (Cydia pomonella) larvae damage apples, pears, and other pome fruits by burrowing inside and blemishing the surface, rendering them unsellable. The DSS on platform.ipmdecisions.net predicts adult flight start using a three-parameter non-linear regression model based on accumulated degree-days. It forecasts the first migration after 151 degree-days, the second after 673, and the third after 1303. The system issues warnings to guide targeted monitoring and control. The model uses daily minimum and maximum temperatures from January 1st and is adapted from Greek research, applicable but not yet validated in Albania, Romania, Bosnia, Croatia, Italy, North Macedonia, Montenegro, Portugal, San Marino, Slovenia, Slovakia, and Spain. Visual content includes a factsheet, control methods, images of damaged fruit, and a QR code.
