摘要
城市昆虫的群落在城市生态系统中常表现出结构较单纯（中间物种较少）、分布的岛屿性、演替的变异快、都参与着人为活动的因素等特点，反映出复杂多变、日新月异的群落演替景象。城市害虫的总体防治应以综合防治的原理、原则作指导，应注意的主要特点有二：一是保护对象，主要是居民，城市建筑及相关设施、城市生活和社会活动的各种用品。二是大多数城市害虫的杀灭不存在保护天敌的问题以及经济阀值的问题。
The study of urban insects should not be divorced from the characteristic of urban ecosystem. Urban ecosystem compares with the agriculture and forestry ecosystem it has own fixed speciticity, the forms of expression frequently are manifold structure or heterogeneity. The community of urban insects is often expressed the more pure structure, (the middle species is fewer) distributed islands and islet character, fast variation of succession. They are all had a hand in the factor man -- made activities and so on, to mirror the scene of community succession that complicated and varied changes with each passing day. The master prevention and cure of urban insects should be guided by the principle of comprehensive control. There are two main characteristics to be attention. The one is to protect the objects, main of them are residents, city building and correlation installation and all kinds of things for city daily and social activity, the two is to wipe out the vast majority urban insects are not existed to protect the natural enemy and the problem of financial.
