摘要
本文简述了农田生态系中天敌昆虫优势种的概念，并根据天敌昆虫的生物学及生态学特性，在自然界中的数量、时间和空间动态以及与害虫的关系，提出了农田生态系中天敌昆虫优势种的评定标准。
This paper deals briefly with the conception of dominant species of natural enemy insects in farmland ecosystem. According to biological and ecological characteristics, the dynamics of space、number and time, and the relationship with insect pests, the dcterminate standards of dominant species of natural enemy insects in farmland ecosystem have been proposed
