摘　　要：昆虫种群动态研究经历了田间种群动态研究、实验种群动态研究和种群系统研究的发展阶段。在田间种群和实验种群动态研究阶段 ,研究重点是描述昆虫种群的动态变化。在田间种群研究阶段 ,主要进行种群聚集与扩散迁移的研究和自然种群的数量调查。通过对实验种群的研究 ,使昆虫种群动态研究得到进一步发展 ,并根据实验的结果提出了种群生长型的特征。在种群系统研究阶段 ,将害虫种群与其所处的环境作为一个系统整体来研究 ,并且在计算机和各种数学手段的帮助下 ,模拟。The study on the insect population dynamics can be divided into three stages, study on field population, study on experimental population, study on population system. In the previous two stages, due to the limitation of experimental conditions and methods, the emphasis of study is to describe the dynamice change of population.In the stage of field population study, most study focus on the congregation and immigration of insect population, the investigation of natural population quantity. With the improvement of emperimental conditions, the study of experimental population growth becomes very important for the further development of population dynamics study. In the stage of population system, integrating the insect and its environment into a whole system has become the new trend of population dynamics study, furthermore, whth the help of computers and many mathematical methods, scientifically simulating, estimating and controlingl insect population has become possible.
