This study, as an attempt to achive the goals including: 1) posibility of non- chemical method application (Cultural practicepruning) in order to control of Anarsia lineatella , 2) Assessment of pruning intensity and its effect on pest control and quantitative and qualitative traits of peach, 3) Recommendation for suitable pruning intensity on peach trees in Qazvin region. This experiment was carried out during 2001-2002 in Feiz abad research station in complete block desing with 3 replications. Treatments including, pruning at ¼, ½, ¾ shoot length that was carried out before blossoming. The factors involved in assessing, consisted of the fruit weight, fruit volume, number of damaged shoots and number of damaged fruits. Results showed that, pruning effected on peach twig borer control and fruit quality and quantity increase. Increasing of pruning intensity was related to reducing of pest damage and better fruit characteristics. The lowest pest damage was correlated with the highest fruit weight and volume in ¾ and ½ pruning intensity.
