The larvae of P. cerasana damage the buds, flowers, leaves and fruits of the cherry tree. In this study, adult population fluctuation of P cerasana and the damage rate were determined in five different cherry orchards in Afyonkarahisar province. The first adult emergence in cherry orchards took place in the third week of May in 2007 and 2008 and the adult population peaked twice. The end of the adult flights differed according to years and cherry orchards and took place between August - October. Similarly, the damage rate of P.cerasana in bouquets and fruits changed according to years and cherry orchards. The damage rate in the bouquet varied between 15.40 % to 56.30% and the damage rate in the fruit varied between 2.80% to 9.80% in 2007 and the damage rate in the bouquet varied between 13.70 - 54.00% and the damage rate in the fruit ranged between 2.00% and 8.10% in 2008. According to the statistical evaluation, the difference between years was not found significant with regard to the damage rate. However, the difference between the orchards in terms of the damage rate was found significant. </p>}, number={2}, publisher={TARIM VE ORMAN BAKANLIĞI EĞİTİM VE YAYIN DAİRESİ BAŞKANLIĞI}, organization={General Directorate Of Agricultural Researh and Policy}
