摘要
在关于单一害虫种群对时间的分布的研究结果的基础上，分３种害虫相互作用形式，研究了害虫复合种群的时间分布，给出了计算和预测害虫复合种群发生数量与发生时间的方法，解决了确定害虫复合种群的经济阈值及制定害虫综合管理系统所需要解决的一些问题。
A time destribution of crop pests in mixed species population regarding the interaction of three pest species was evaluated based on the time destribution in single species populaiton. A method to calculate and forecaste the quantity and growing time of crop pests for mixed-species population was proposed.Some problems of the economic threshold in mixed-species population,and preventive system for crop pests were solved.
