| 摘 要： | 利用群落多样性指数，均匀性指数，丰富度及物种个体总数等指标，对四川棉田昆虫群落进行了模糊聚类分析。结果表明，四川棉田昆虫群落的季节变化格局可划分为５月底以前，６～７月份，８月份，９月份及其以后４个阶段，并结合气候，物候变化，讨论了各阶段内主要害虫，天敌的发生特点和害虫治理策略。

| Abstract: | Fuzzy clustering analysis was made of the insect communities in cotton fields of Sichuan province with community diversity indices,evenness indices,abundance degree and total number of species. The seasonal variation pattern was divided into 4 stages, viz. before June, June to July,
August and after August. The characteristic features of the dominant pests and their natrual enemies and the strategies of pest management are discussed, taking into consideration the climatic and phenological development at each stage. |
