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。
The structure and succession of insect community in corn seed coating, omeprazole and control fields were analyzed. The results showed that the coated field protected the natural enemies while controlling the pests and played a two-way regulating role on the insect community. The spray field was very destructive to insect communities, causing the re-rampant pests in the middle and late stages. The structure is stable, but the occurrence of major pests is still heavy. This provides a new approach to the comprehensive management of pests in corn fields.
