| 摘 要： | 通过对麦田天敌消长规律的调查分析,从害虫防治和天敌利用的角度出发,提出天敌的最低利用指标,并作为划分天敌发生盛期的依据。同时提出用天敌高峰日发生量和发生盛期天数、后期网捕天敌量作为划分天敌发生程度的指标,并在麦田天敌监测资料统计中进行了具体应用。

| Abstract: | The population dynamics of natural enemies in wheat fields were monito red. For the purpose of preservation and application of natural enemies, the min imum population thresholds for use of natural enemies were proposed and set up a s baselines to calibrate the abundance duration of natural enemies in the season . Quantities of natural enemies in population peaks, numbers of days of populati on abundance and amounts of natural enemies trapped by scoop nets were put forwa rd as criteria indexes of occurrence degrees. Those criteria indexes were applie d in statistic analysis of population surveillance data of natural enemies in wh eat fields. |
