摘要
本文系统调查上海郊区甘蓝田节肢动物群落结构及其变化动态，其鉴定出节肢动物２６种．分属于１８个科，其中害虫１０种；天敌１６种．另外对主要害虫和天敌的周年消长动态以及两个甘蓝品种上节肢动物群落的物种丰富度，多样性指数、均匀度和优势集中性指数等参数及其变化动态进行了分析．
Systematic field surveys were carried out to study the structural changes of arthropod community in cabbage fields in Shanghai suburbs. The arthropod community of cabbage fields in three regions compeited 26 species, belonging to 18 families. Seasonal population changes of dominant components were described. Temporal changes of abundance, diversity, eveness, and dbminant concentration index vaines ofarthropod community were analyst. Action threshold was emphasised in the development of optimal management strategies for cabbage pests.
