| Abstract: | Morphology, damage characteristics, occurrence dynamic and outbreak causes of Dichocrocis punctifera lis Guenée were investigated and organic prevention measures were researched in Huai-rou district, Beijing. The results showed that Dichocrocis punctiferalis Guenée 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. |
