摘要
通过田间调查，在 Ｗｉｎｄｏｗｓ９８平台上利用 Ｖｉｓｕａｌ Ｂａｓｉｃ６．０统计编程，系统研究了麦田害虫及其天敌从５月９日至６月２日的相对多度、物种丰富度、生态优势度、多样性指数和均匀度的变动。表明麦田是相继作物害虫的重要天敌源，应保护利用。
Through the investigation of fields and programing with Visual Basic 6.0 in the flat- base of Windows 98,the species component and species riceness, dominance, ecological concen- tration, diversity and evenness of insect pest and natural enemy community in wheat field were studied in detail from May, 9 to June , 2. The results showed that these natural enemies were the enemy source of some crops in succession and should be protected to utilize.
