群落是农田生态系统的重要结构之一。人们希望通过利用生物之间负反馈的作用,来调节控制害虫的数量,达到维持自然生态平衡的目的。为此对农田昆虫群落动态的了解,有助于揭示害虫种群消长的原因,有助于害虫综合治理的设计。前人在达方面作过许多研究,朱弘复对棉花昆虫群落(1978、1961),陈常铭对稻田害虫群落(1963), Community is one of the important structures of farmland ecosystem. People hope that by using the role of negative feedback between organisms to control the number of pests, so as to maintain the natural ecological balance. This understanding of the dynamics of insect communities on farmland will help reveal the causes of pest population decline and contribute to the design of integrated pest management. Much research has been done on these aspects. Zhu Hongfu studied on cotton insect community (1978,1961), Chen Changming on paddy field pest community (1963)
