摘　　要：对北京市怀柔区板栗桃蛀螟的形态和危害特征、发生动态和大发生原因进行了调查，研究了板栗桃蛀螟的有机防治措施。结果表明，桃蛀螟在北京发生3代，第1代、第2代主要危害桃、杏、玉米，第3代转移到板栗危害，生物农药施安的防效与化学农药辛硫磷，可用于有机板栗生产；采用综合防治措施可以将板栗虫果率由20％～30％降低到4％以下。Morphology, damage characteristics, occurrence dynamic and outbreak causes of Diehocrocis punctifera lis Guenee were investigated and organic prevention measures were researched in Huai-rou district, Beijing. The results showed that Dichocrocis punctiferalis Guenee produced 3 generations per year in Beijing, the first and the second generation mainly damaged peach, apricot, maize, while the third generation could transfer to chestnut; The biological pesticide ＂Shi-an＂ and chemical pesticide ＂phoxim＂ were suitable for the production of organic chestnut; The rate of worm fruit reduced from 20% -30% to less than 4% by using comprehensive control measures.
