Based on a systematic field investigation and laboratory experiments, the structures of arthropod communities and the evalution of dominant predatory enemies in cabbage fields of different seasons were studied. The main results were as follows:1 The structures and their dynamics of arthropod communities in cabbage fields1.1 Species composition and population dynamics of each species of the arthropodcommunities in the cabbage fieldsThe research results showed that the occurrence of Pieris rapae in spring cabbage fields was relatively grave.

本文在田间系统调查和室内试验的基础上，对不同季节甘蓝田节肢动物群落结构及捕食性天敌优势种的评价进行了研究，主要结果如下：1甘蓝田节肢动物群落结构及其动态1.1节肢动物群落物种构成和各种群数量动态研究结果表明，春甘蓝田菜青虫的发生比较严重，菜青虫在调查期间种群数量呈上升趋势，5月初高峰期平均每株甘蓝接近20头；菜蚜与小菜蛾的发生相对较轻，菜蚜在5月中旬有个明显高峰。
