| Abstract:
Codling moth, Cydia pomonella (L.)(Lepidoptera: Tortricidae) is the most important pest in some apple orchards in Romania, with damage increasing in recent years. In many cases, control measures do not lead to good results. In order to improve the warning system, modelling Codling moth (CM) phenological development based on temperature sums is essential. To understand the mechanism of seasonal occurrence of this insect pest, a population dynamics model that explicitly incorporates the effect of temperature on development was used. Knowledge of the phenology of CM is likely to allow the prediction of the timing of appearance of each development stage, which will facilitate improved timing of control measures. Model predictions were compared with observed pheromone trap captures at Baneasa, Romania. The results demonstrate that the timing of appearance of adult population varied considerably between years. | |
