In this study, the phenological  model to control of the Codling  moth [(Cydia pomonella L.)  (Lepidoptera: Tortricidae)] was investigated and the  basis data on the forecasting and warning system in walnuts were obtained.  Therefore, the applicability of the degree-day model in the framework of the forecasting and  warning system applied the control of the Codling moth in apple orchards were  investigated in walnut. In this study, the pheromone traps, visual fruit  control, and the sum of effective temperatures and the corrugated board methods  were used in walnuts orchards in Oğuzlar (Çorum) from 2007 to 2009. The first  adults of the Codling moth were captured on April 21, 2007; on April 30, 2008  and on May 1, 2009. The first larvae emergence of the first generation May 23,  2007; May 21, 2008 and June 2, 2009 and the sums of effective temperatures in these  days were respectively 250,31; 258,46 and 247,18 degree days. The first larvae  emergence of the second generation were July 23, 2007; July 21, 2008 and July  31, 2009. The sums of effective temperatures in these days were respectively  782,39; 727,18 and 717,79 degree days in walnut in Oğuzlar. The sums of  effective temperatures in each year in walnut were shown the parallel with 250 degree  days for the first larvae emergence of the first generation and 800 degree days  for the first larvae emergence of the second generation in the apple. These  results were shown hopeful that  the degree-day model in the forecasting and warning system applied  the control of the Codling moth in apple orchards was able to use for walnut.
