摘 要:板栗害虫在我国广泛分布、危害严重,本研究对其危害特点、发生规律及防治技术进行综述。提出防治应贯彻"预防为主、综合防治"的植保方针,坚持以林业防治为基础,优先采用生物防治,协调利用物理防治,科学合理应用化学防治,创造有利于板栗生产、不利于害虫发生危害的生态环境,把板栗害虫损失控制在允许的经济阈值以下,使板栗中的农药残留量控制在国家规定的范围以内。More than 454 species of insect pests damaging Castanea mollissima of 91families and 11orders have been reported in China.The paper intends to summarize the damage,occurrence and control method.The paper also proposes that control strategies of chestnut insect pests should implement the policy of "prevention first and integrated control",adhere to forestry-based prevention and control,give priority to the use of biological control methods,and combine physical control with a scientific and rational application of chemical control,so as to create a favorable ecological environment for chestnut production,control the loss of chestnut pest below the economic threshold,and reduce the pesticide residues on chestnut through the dose allowed by the government administration.
