从１９４９年开始，我国森林害虫治理策略发展的第一个时期已经过去，第一个时期包括了三个阶段，即害虫防治（１９４９～１９６３）、协调防治（１９６３～１９８０）、综合治理ＩＰＭ（１９８０～１９９６），ＩＰＭ由于融合了生态学理论，是该时期的治虫策略发展的最高阶段，但它是以杀虫剂治虫为基础的。第二个时期即虫害的可持续控制ＳＰＭ时代的到来（１９９６），它的产生是国家的林业可持续发展及害虫治理中迫切需要解决的难题共同作用的结果。ＳＰＭ是建立在生态体系这个基础上的治虫策略，这是治虫理论上的变革，但急需研究和解决的问题包括：昆虫群落多样性测度ＩＣＤＭ，虫害频度ＰＦＩ，多样性测度阈值ＤＴＶ。
Since 1949, the first period of development of forest pest management strategy in our country has passed. The first period consists of three stages: pest control (1949-1963), coordinated prevention and control (1963-1980) and comprehensive management of IPM 1980-1996). As a result of the integration of ecological theory, IPM was the highest stage of the development of the pest control strategy during this period, but it was based on a pest control insecticide. The second phase, the sustainable control of pests and diseases The coming of the SPM era (1996) is the result of the combined effect of the urgent problems that need to be addressed in the sustainable development of forests and pest management in the country. SPM is a pest control strategy based on the ecological system. This is a theoretical change of pest management. However, the urgent need to study and solve the problems include: Insect community diversity measure ICDM, pest frequency PFI, diversity measure threshold DTV.
