摘　　要：分析了玉米种衣剂包衣田，氧化乐果喷药田，对照田的昆虫群落结构和演替。结果表明：包衣田在防治害虫的同时，保护了天敌，对昆虫群落起到了双向调节作用，喷药田对昆虫群落的破坏性很大，导致了中后期害虫的再猖獗，对照田昆虫群落结构较稳定，但主要害虫的发生仍然较重。这为玉米田害虫的综合治理提供了一条新的途径。This paper studied on the structure and succession of insect communities in 3 types of corn field. Seed coating formulation spray insecticide other field. The result showed that seed coating formulation field was effected control pest and protected natural enemy. It adjust insect communities in two dimensions. The spray insecticide of corn field ecological balance and cause to resurgence of compiled insect communities.
