The control of apple leaf roller moth can start from four aspects: First, artificial control. During the dormant period of apple trees, old cracks and dry leaves stuck on branches were scraped and burned. In the spring, combined with thinning and thinning fruit, the leafhoppers were removed and concentrated to eliminate. Second, it traps adult worms. Can be used black light lamp, sweet and sour liquid (by brown sugar 1, vinegar 2 copies, water 8 parts of the ratio of preparation), sex hormone traps, etc., from the beginning of adult emergence can be tempted to kill the leaf roller moth adults. Third, biological control. The release of Trichogramma or the use of granuloviruses and insect juvenile hormones in orchards is well controlled. Fourth, chemical control. The buds of the apple trees were sprayed with 1000 times of Bt emulsion or 1000 times of No. 6 insecticide bacteria before flowering. The first generation of larvae in the early stages of damage can be sprayed with a 1000-fold suspension of juvenile urea 3, or 2.5% of 2.5% gongfu EC.
