     The codling moth (Cydia pomonella L.) is one of the most important pests existing in the apple orchards of the Hiran-Iraq northern part, according to the climate of Iraq Codling moth has 2‒3 generations per year. This study conducted to calculate the relation between distribution of codling moth and canopy aspects and also to estimate the relationship between diameter and height of trees with fallen fruits. The results revealed that the highest infestation recorded by second generation of codling moth which was 0.952, the highest mean values of the fallen fruit were 38.600, regarding canopy aspects the highest infestations were recorded in the South followed East and North side compare to West or Middle side, and also this investigation confirmed that there is a significant influence of tree height and rate of infestations by codling moth. This study concluded, that canopy aspects, height and diameter of trees, with climate condition such as temperature and humidity effect apple orchards infestation by codling moth.
