Mudanjiang fruit production in apple accounted for more than 80%, annual output of more than 20 million kg. However, since 2069, the harm of peach moths has become more and more serious. It is estimated that the loss will amount to over one million jins. It is an urgent matter to be solved that the high yield will not bring loss of food value and affect income. To this end, I conducted in 1975 to 1976 with the production of Peach moth prediction and control methods of test. After 3 to 4 years of production promotion, has achieved very good results.
